Foreword by D. Seebach
Organic Syntheses Based on Name Reactions When studying chemistry
at the Technische Hochschule Karlsruhe, more than 50 years
ago, we had tomemorize close to 50 Name Reactions for the final
examination in organic chem-
istry. The then one and only book on Name Reactions was
Krauch-Kunz’s Reaktionen der Organischen Chemie, which tried to be
complete at the time. In the mean time, synthetic organic
methodology has experienced an explosive expansion, which is due to
two fundamentally dif-
ferent types of developments: (i) the classical reactions have been
modified to become regio-,
diastereo-, and enantioselective, and to become catalytic (cf.
organocatalysis). (ii) The—mostly
catalytic—use of transition-metal derivatives has enriched organic
synthesis with new types of reactions (cf. metathesis), which can
almost all be rendered enantioselective by employing
chiral ligands on the metal centers. Many of the resulting
procedures for carrying out certain
transformations have turned out to be of broad scope and to be
generally reliable, so that—for
brevity—they were named after their inventor(s) in synthetic
discussions, and that’s all about
Name Reactions. It is, therefore, not surprising that several
monographs on this subject have
appeared and that new editions of books on Name Reactions are
essential.
This book first appeared in 1994, a second edition in 2002, and now
the third one in 2011,
with the number of Name Reactions covered increasing from ca. 450
to 550 to over 700, and the
number of cited papers from 2100 to 3300 to over 6000. Still, the
size of the volume(s) remained
“manageable.” Of course, the authors had to make, with a personal
bias, decisions about which
reactions to include and which to replace (an evolutionary
process!). In fact, when browsing
through the three editions, one can get the impression that they
are quite different books, in
spite of the common unique features, which are, first of all, a
typical specific experimental pro-
cedure and a proposal of a mechanistic course for the covered Name
Reaction. Then, there are
updated references to most recent publications and cross-references
to similar transformations
with a different name; the quality of the formulae has greatly
improved; there are most useful
indices of names, reagents, reactions, abbreviations, and group
transformations; last but not
least, there is a new, larger section entitled “An Overview of
Synthesis-Related Name Reac-
tion,” listing, for instance, all Name Reactions, in which
aldol-type transformations; cycload-
ditions; or S, Se, Si, Sn, Bi compounds are involved, to name only
three of the 40 entries in this
section. A scientific book without an excellent index for access to
its content is not a good book;
this one is, indeed, excellent, not least because of these
indices!
I went through the pages of this third edition with great pleasure.
I learned about some trans-
formations, which were new to me. To some extent, it was a learning
experience like when I
studied a textbook as a student. The book has, indeed, textbook
character and could be used in
lab courses as a “cook book” and in advanced organic chemistry
courses for problem-solving
sessions and as a source of exam questions—without requesting that
the students actually mem-
orize the Name Reactions, as in the old days: to cover the
fundamental reactivities of organic
compounds they must learn names connected with some
transformations, reagents, and mech-
anisms. On the other hand, a discussion between top synthetic
organic chemists (cf. specialists
in total synthesis of complex natural products, “synthetic
engineers”), with a life-long experi-
ence, will inevitably be full of reference to Name Reactions; when
the name “pops up,” there is
immediate mutual understanding and agreement that there is mention
of a generally applicable
and reliable chemical transformation.
In our time of online data bases, such as Chemical Abstract’s
Scifinder, Beilstein/Gmelin’s
Reaxys (ReactionFlash), Houben-Weyl’s Science of Synthesis, or even
Google and Wikipedia
(I have successfully tested some of the more “fancy” Name Reactions
therein), it is appropriate
to ask the question: “Who needs a book on Name Reactions?” The
above-mentioned unique features of the third edition of Organic
Syntheses Based on Name Reactions will make sure
that many organic chemists in academia and in industry will want to
have this book on their
shelves. The success of the second edition and the call for a third
edition are evidence for this
view. Name Reactions are at the core of the art of organic
synthesis!

Foreword by S. Danishefsky
What’s in a Name Reaction?—A Lot To my delight, I discovered that
fascinating combination of rigor/hypothesis, hard-core the-
ory/intuition, and commercial-level practicality/artistic elegance
known as organic chemistry
in a 1954 course at Yeshiva University. It was already clear that
one of the challenges of Orgo
(particularly for the pre-meds) would be the systemization of a
huge body of factual data, allow-
ing for retrieval of critical information at critical times (exams,
etc.). Our official class textbook
was authored by Raymond Brewster at the University of Kansas.
However, the achievers in the
course, whose ranks I sought to enter, also purchased a book
written by Louis andMary Fieser at
Harvard. Though these two tomes actually covered a very similar
body of chemistry, there were
some notable differences in style. Brewster attempted to
rationalize the seemingly unmanage-
able collection of facts in Orgo under what was then a newly
emerging theoretical construct,
encompassing mechanisms (still early days for “curved arrows”),
effects of structure changes
on reactivity, and some of the then very new ideas regarding
stereochemistry.
The Fiesers, in turn, placed heavier emphasis on analogy arguments.
Fieser mechanisms in
those days tended to focus on proposed affinities between
substrates and reactants with a high
premium on identifying likely leaving groups to be anticipated from
various displacements
and condensations. Much of this line of mechanistic conjecture was
captured in a “lasso-type”
presentation, wherein stable entities (cf. inter alia water,
alcohols, amines, halides, etc.) were
extruded to drive otherwise mysterious processes forward.
More so than Brewster, the Fiesers utilized the medium of Name
Reactions to facilitate dis-
course. The Name Reaction device in the Fiesers’ treatment tended
to focus on overall reaction
phenomenology (addition, elimination, aliphatic substitution,
aromatic substitution, cycloaddi-
tions, condensation, etc.) rather than on intimate goings on below
the surface. Thus, for in-
stance, the Mannich Reaction would be seen as one which joined a
secondary amine a to a
carbonyl group (at that time almost always a ketone) through one
linking carbon (usually form-
aldehyde) by extrusion of water. With the explosive growth of the
number of valuable reactions
in organic chemistry and with growing insights into mechanistic
issues, the importance of
Name Reactions grew. The Name Reaction tended to embrace not only a
transformation but
also a particular mechanistic idea. As such, Name Reactions
facilitated discussions of both
mechanism and synthesis. Hence, the role of the Name Reaction
classification in facilitating
discussion became central. Two people, more or less on the same
structural and mechanistic
pages, could communicate a remarkable amount of information and
even prospective ideas
through the use of well-chosen Name Reaction descriptors. Even
today, I find Name Reactions
of increasingly great value in organizing my own thoughts about
synthesis as well as mecha-
nisms, and in sketching out, if qualitatively, the landscape of our
science.
In principle, it might have been argued that the need for this type
of classification is decreas-
ing in the face of powerful searching technology for canvassing
large bodies of information,
including structures, and even reaction types. Surely no one could
argue that, in this day
and age, the medium of the Name Reaction is the primary way of
conveying descriptive
and mechanistic information. However, the Name Reaction system is
still a major aid in
classifying large amounts of information in digestible form. As a
classroom teacher, mastery of
the key Name Reactions is high up on my list of charges to the
class on day one of the course.
Accordingly, I was very pleased to respond to the invitation of
Professor Alfred Hassner to
comment on his emerging book, which updates, in a most valuable
way, an increasing number
of Name Reactions. Even 57 years after taking the course described
above, I remain totally ex-
cited at the concept of the awesome power of chemical synthesis.
The notion that any structure
(within reason!), of which the human mind can conceive, is a
possible target for chemical syn-
thesis remains to me one of the most noble ideas in the
epistemology of science. The time is long
since past when triumphs in synthesis are viewed primarily as
personalized mountain climbing
exercises. The macho/bravado element is still there, as it is in
all artistry-intensive human un-
dertaking but is far less central. Synthesis is really about the
capacity of the human imagination
and human resourcefulness to find ways of joining molecules in a
precise, disciplined way with
high levels of control. Many of these molecules are of immediate
interest from a material sci-
ence or pharmaceutical perspective. Others are of interest as
probes for evaluating hypotheses
in structure theory or in biological signal transduction cascades.
Aside from its intrinsic appeal
to the artistic impulse, synthesis plays an important role in human
progress.
The opportunity of dedicating one’s intellectual imagination to
complex problems, many of
which are apt to serve the needs of a growingly needful society,
must be seen as a great priv-
ilege. The means for codifying information, which is central in
this regard, while rewarding the
initiators (even posthumously) of what becomes a Name Reaction
retains its special cultural
status in assisting the forward march of our science. Name Reaction
assignments have about
them a significant element of intellectual history. However (and
needless to say), the tracing
back of all the antecedents of an idea is actually an endless
process. What Name Reactions
are really about is an agreed upon vocabulary, by convention, for
communicating concepts
in concise but human terms, befitting one of the most
esthetics-intensive of scientific activities,
that is, organic synthesis.
Not surprisingly, with the growing complexity and urgency of
problems with which a sci-
entist is faced comes an increasing need for multidisciplinary
ventures. I would argue (though
not without an admittedly strong dose of field chauvinism) that the
truly unique gift that chem-
istry brings to such urgent collaborations is its aspiration for
achieving unencumbered synthe-
sis. This expansiveness distinguishes chemical synthesis from the
unbelievably powerful (more
circumscribed) engine of biosynthesis. Melding the skill sets of
biology-mediated synthesis and
unencumbered chemical synthesis is one of the great opportunities
at the chemistry/biology
frontier.
While it is well to think about issues of abstract logic and
strategy, and ways in which they
influence chemical synthesis, the actual drivers of the field are
the huge advances in reaction
feasibility arising from fundamental studies of methodology and its
enabling mechanisms. In
short, the often unsung heroes of the awesome triumphs in chemical
synthesis are the subjects of
these Name Reactions (not to speak of their students and
postdocs!).
I am pleased to congratulate my friend and field colleague, Fred
Hassner, and his coauthor
Irishi Namboothiri. They surely need have no doubt that this latest
book on Name Reactions
will be read in a continuing way and with great pleasure by their
fellow scientists/artists.

Preface to the Third Edition
The past 10 years, since the publication of the successful second
edition of Organic Syntheses Based on Name Reactions, have
witnessed a renaissance in organic synthesis; especially in the
discovery of new reagents and chiral catalysts that have spurned
development of asymmetric
syntheses. This has made possible the synthesis of a significant
number of complex natural
products in an enantioselective manner. In the process one
continues to notice that many syn-
thetic methods, reagents, and reactions are being referred to in
the organic chemistry research
community by the names of their discoverers or developers.
The proliferation of published material in chemical journals has
led to journal requirements
that authors be more succinct in their publications (witness the
fact of extensive Supplemental
Material in many journals); hence one often sees procedures or
methods referred to by Name
rather than by lengthy explanations. For the student of organic
chemistry, there is the advantage
of mnemonic that some prefer.
One of the comments on the second edition of Organic Syntheses
Based on Name Reactions was that we omitted some older and less
utilized Name Reactions that had appeared in the first
edition. Hence for the sake of being comprehensive, we decided to
keep such Name Reactions
in this revision. Further, we have added over 100 new Name
Reactions, the choice of which, of
course, reflects our own bias, and for that we apologize.
All reactions have been brought up to date by including recent
references where available. If
possible, we have consulted living authors about their Name
Reaction. In some cases, no recent
references were found, and this may reflect the fact that more
modern or simpler reactions are
now preferred.
It appears that people hesitate to refer to reactions by name if
they bearmore than two or three
names. This made it desirable to break up reactions such as
Hunsdiecker–Borodin–Cristol–
Firth–Kochi into the more natural Hunsdiecker (Ag salts of RCOOH),
Cristol–Firth (HgO
and RCOOH), and Kochi (Pb derivatives). Similarly, in some cases,
we separated a Name Re-
action from its asymmetric variant, such as the Michael addition or
Diels–Alder reaction, in
order to avoid them being too cumbersome. Even so, since there are
now several asymmetric
catalysts known for the same reaction, lumping all together would
be quite unwieldy. Further,
we felt it was relevant to finally give credit to major
contributions of chemists who developed
such well-established reactions as free radical dehalogenation with
Bu3SnH (now Kuivila–
Beckwith) or carbodiimide coupling reagents (now Sheehan). Ionic
liquids and their asymmet-
ric version are also included. It will be noticed that quite a few
name reactions are related to well
known reactions (Friedel–Crafts, aldol, Michael, Grignard) but are
known by different names.
Some reactions are often known by one name but can also be referred
to by another name,
and this we tried to reflect in the introductory statement by
including the other names as
well; for instance, Grob Fragmentation also known as
Grob–Eschenmoser, or Fokin
Cu-catalyzed Click reaction also known as Fokin–Sharpless–Meldal,
or Hunsdiecker also
known as Hunsdiecker–Borodin.
There is always a big problem combining the chemistry described by
the originator of a
Name Reaction with the chemistry developed later and further
adjusting it into limited space.
Obviously, after the original publication, the reaction has
sometimes mutated to quite a differ-
ent animal.
The Overview section is a new and very important feature to the
third edition. For instance,
the Overview lists syntheses of olefins by CþC bond formation (over
16 Name Reactions) or by
elimination (over 30 Names). This is not only useful for advanced
organic chemistry students,
but should be very valuable to the researcher as at a glance
comparisons of related methods for
synthesis of particular functional groups are provided. Details can
then be found under the
names. Other Overview sections include asymmetric syntheses,
syntheses of amine, cyclopro-
panes, 5- and 6-membered ring heterocyles and many more. Of course
this is not meant as a
textbook and is limited to named reactions.
In addition the last few years have seen a proliferation of Pd-
(and other metal-) catalyzed
coupling reactions; in fact several Nobel prizes were awarded in
this field. We have therefore
also included a brief Overview of Pd catalyzed Name Reactions with
a general reaction pathway.
Wherever possible in the new edition, we have alluded to the
mechanism of reactions (prob-
able reaction pathway) by providing an intermediate or a
description, yet leaving some freedom
for students to supplement details.
We limited the coverage of reactions since we preferred to keep the
size and the cost of the
volume manageable.
The new addition maintains the successful format of providing
important references (over
6000); in each case, this includes one of the first references to
the reaction and a review ref-
erence (marked R) where available. Asymmetric syntheses are marked
with an *. References
to books are generally not included. Further, a brief example of an
experimental procedure is
provided in most cases. In the experimental, we often refer to
“work up” which is usually meant
to include, where necessary, washing, drying, extraction,
evaporation, and purification
(chromatography).
Important features of this monograph are the indexes, which should
be helpful to the reader:
A name index with cross references to multiple names
A reagent index
A reaction index
A functional group transformation index, which allows one to search
for conversions of one
functional group to another.
As well as a condensed Overview that includes, among others, aldol
type reactions; asymmet- ric reactions; cyclopropanation;
oxidations; rearrangements; S, Se, Si, Sn derivatives, etc. The
Overview should prove valuable to the synthetic chemist as well as
to students in universities,
when searching for or comparing procedures. In fact this format has
led the second edition (even
without the Overview) to being adopted as a text in advanced
organic chemistry courses.
We thank our families for their understanding during the extensive
work on this book and are
grateful to Dr. Simcha Meir, Prashant Pavashe, Sundaram Rajkumar,
and Mamta Dadwal for
their invaluable help in bringing this volume to fruition. Mistakes
often creep in and we are
greatly indebted to Dr. Thomas Allmendinger and Mr. Simon
Allmendinger for checking
the manuscript and suggesting corrections that had been overlooked.
We are very grateful to
our editor Dr A. Shell for constant encouragement, suggestions as
well as proofreading. This
monograph is dedicated to the memory of Cyd Hassner and of our
children Suzie, Douglas and
Erica.
Preface to the Second Edition
The success of the first edition of “Organic Syntheses Based on
Name Reactions and Unnamed Reactions” and the proliferation of new
Name Reactions are the reason for this new revised
edition. It became obvious that many new reagents and reactions are
being referred to in the
organic chemistry research community by their names. Hence, in
addition to over 170 new re-
actions (previously referred to as Unnamed Reactions) in the first
edition, we have included in
the second edition 157 new Name Reactions bringing the total to
545. However, we have elim-
inated the term “Unnamed Reactions” from the title of the
monograph, since these reactions are
now no longer unnamed. Furthermore, we omitted some older and less
utilized Name Reactions
that appeared in the first edition but have included them in the
Name Index, by providing ref-
erence to the page number in the first edition (e.g. Baudisch 1-27,
refers to first edition, p.27).
The new additions are all synthetically useful or not immediately
obvious transformations.
In choosing them, emphasis was placed on stereoselective or
regioselective reagents or reac-
tions including asymmetric syntheses. The latter are particularly
timely with the recent Nobel
Prize in Chemistry awarded in this area.
Again we admit our own bias in choosing from the many interesting
newer transformations
reported in the literature. Where possible we have tried to consult
with the Name Reaction
major author. We apologize if inadvertently important reactions
were omitted.
We have maintained the useful format of providing important
references (over 3,300); in
each case this includes one of the first references to the reaction
and a review reference where
available. Furthermore, an example of an experimental procedure is
provided.
Important features of this monograph remain the indexes, which
should be helpful to the
reader:
A reagent index; A reaction index, e.g. acylations, asymmetric
synthesis; epoxidation, heteroannulations, re-
arrangements, etc.; as well as
A functional group transformation index, which allows one to search
for conversions of one functional group to another. The latter has
proved valuable to the synthetic chemist search-
ing for pathways to perform such synthetic procedures.
Hence, the monograph should be of interest to chemists in industry
and academia. In fact this
format has led to the monograph being adopted as a text in advanced
organic chemistry courses.
We thank our families for their understanding during the travail on
this book and are grateful
to TEVA Pharmaceutical Co. for their support.
This monograph is dedicated to the memory of my dear wife Cyd
(A.H.).

Non nova sed nove
Preface to the First Edition
And these are the names. . . The above are the opening words of
Exodus, the second book of the Pentateuch. Already in
ancient times, names were important in association with events. As
organic chemistry devel-
oped during the 20th century, researchers started associating
synthetically useful reactions with
the names of discovers or developers of these reactions. In many
cases such names serve merely
as a mnemonic, to remember a reaction more easily; there are few
chemistry undergraduates
who do not know what the Friedel-Crafts reaction is.
In recent years there has been a proliferation of new reactions and
reagents that have been so
useful in organic synthesis that often people refer to them by
name. Many of these are stereo-
selective or regioselective methods. While the expert may know
exactly what the Makosza vi-
carious nucleophilic substitution, or the Meyers asymmetric
synthesis refers to, many students
as well as researchers would appreciate guidance regarding such
“Name Reactions”.
It is in this context that we perceived the necessity to
incorporate the older name reactions
with some newer name reactions or “unnamed reactions”, that are
often associated with a name
but for which details, references and experimental details are not
at everyone’s fingertips. This
was our inspiration for the current monograph “Organic Syntheses
Based on Name Reactions and Unnamed Reactions”.
In particular, we thought it would be useful to include
cross-references of functional group
transformations and an experimental procedure, so that the reader
will be able to evaluate the
reaction conditions at a glance; for instance, is this reaction
carried out at room temperature or at
200 C? For 1 h or 5 days? Are special catalysts required? How is
the reaction worked up, what
yield can be expected?
The choice of which reactions to include is not an easy one. First
there are the well known
“Name Reactions”, that have appeared in various monographs or in
the old Merck index. Some
of these are so obvious mechanistically to the modern organic
chemistry practitioner that we
have in fact omitted them; for instance, esterification of alcohols
with acid chlorides – the
Schotten-Baumann procedure. Others are so important and so well
entrenched by name, like
the Baeyer-Villiger ketone oxidation, that it is impossible to
ignore them. In general, we have
kept older name reactions that are not obvious at first
glance.
In some cases we have combined similar reactions under one heading,
for instance, the
Hunsdiecker-Borodin-Cristol-Firth decarboxylative bromination. It
is not a simple task to de-
cide whether credit is due to the first discoverer of a reaction or
to its developers. Often an im-
provement on a method is more useful than the original discovery,
and usually one reaction
owes its inception to some previous discovery; non nova sed nove.
Except in the case of reactions that have been known for a long
time under shared names, we
often took the liberty to include in the title, as well as in the
references (here to save space), only
the name of the major author; for this we apologize to the
co-authors, whose contributions are
often seminal. For reactions named after contemporary authors, we
have tried to consult the
authors about choice of examples, etc. This led, for instance, to
the Mannich-Eschenmoser
methylenation.
Among the newer reactions, we have chosen those that are not only
synthetically useful,
but, at first glance, not immediately obvious transformations.
Another criterion was the stereo-
chemical implication of the process. Yet, we admit our own bias in
choosing from the plethora
of novel transformations that have appeared in the literature over
the past 30 years or so. Space
limitation was by necessity a criterion. Nevertheless, we have
included approximately 450
name reactions and 2100 references. We sincerely apologize if we
have inadvertently omitted
important reactions.
In all cases we have tried to include the first reported reference,
a reference to an experimen-
tal procedure, and whenever possible, a review reference (journal
or Organic Reactions). In general, we did not include references to
books, series of monographs, or toOrganic Syntheses; chemists will
of course consult these where available.
Furthermore, we have compiled four indices, which should be helpful
to the reader:
1. A names index with cross references to multiple names;
2. A reagents index; 3. An index to types of reactions, e.g.
alkylations, stereoselective reductions, cyclizations,
etc.; and
4. Most important for the synthetic chemist is an index to the
synthesis of functional groups, e.g., synthesis of alkenes from
ketones, as well as conversion of ketones to alkenes.
We thank our families for their support and understanding during
the travail on this book.
Special thanks are due to my son, Lawrence Hassner, for
constructive suggestions and invalu-
able help.
We are grateful to the TEVA Pharmaceutical Co. for support of this
project.

ABIKO–MASAMUNE Asymmetric Aldol Reaction
Asymmetric aldol reaction between propionate esters e.g. 1 and
aldehydes 2 using (þ) or () nor-
epinephrine (or norephedrine) as a chiral auxiliary; proceeds via
ester boron enolates 4. Formation
ofpreferentially syn3 oranti2 productsdependson thebulkiness of
alkyl in the dialkylboron triflate, as well as on the chiral
auxiliary, the tert amine and temp (lower temp favors kinetic anti
product); the large dicyclohexylboron triflate 4 leads
predominantly to anti products 3 via E-boron ester
enolates, while dibutylboron triflate and DIPEA give more syn
aldols.10 Double aldol reaction
of acetate esters is possible.6 Methoxyacetates give syn-glycolate
derivatives with high
selectivity.8 Compare with Evans syn-aldol and Crimmins anti-aldol
(via ketone enolates).

anti Selective aldol (3).5 To a solution of norepinephrine ester
(1R, 2S)-1 (4.80 g, 10 mmol) (R1¼ Bn,
R2 ¼ Mes) in CH2Cl2 (50 mL) in an oven-dried 500 mL flask under
nitrogen was added via syringe
TEA (3.40 mL, 24 mmol). A solution of dicyclohexylboron triflate
(1.0 M in hexane, 22 mL) was
added over 20 min at 78 C and stirring was continued for 30 min.
IBA 2 (R ¼ iPr, 1.08 mL,
12 mmol) was then added dropwise and the mixture was stirred at78 C
for 30 min and then brought
to r.t. (1 h). After quenching with a pH 7 buffer (40 mL), MeOH
(200 mL) and 30% H2O2 (20 mL)
were added slowly. After stirring overnight at r.t. and usual
workup and evaporation a solid was
obtained which was crystallized from hexane (150 mL) to give crude
3 (4.4 g). Removal of cyclohex-
anol from the mother liquor and chromatography provided an
additional product (0.6 g). Crystalliza-
tion from EA–hexane (1:5) afforded 4.77 g (87%) of pure anti
(þ)-3.
syn Aldol (3).5 As above, reaction of ester (1R, 2S)-1 (R1 ¼ Me, R2
¼ octahydroanthracenyl(OHA),
0.4 mmol) with n-Bu2BOTf (0.8 mmol) and iPr2NEt afforded 3-syn

Diethyl hydroxybenzyl phosphonate (7).10 Phosphite 6 (1.50 mmol)
was added to benzaldehyde 5
(1.0 mmol), iPr2NEt (1.50 mmol), and (S)-BINAPO (10 mol %) in DCM
(4 mL) at 78 C. SiCl4 (0.75 M DCM solution, 2.0 mL) was added over
2 h with a syringe pump. Water (4 mL, deionized),
sat aq NaHCO3 (10 mL), and EA (10 mL) were added, the mixture was
stirred for 1 h and filtered
through celite. Extraction with EA (3 10 mL), usual workup, and
chromatography (silica gel
15 g, hexane:acetone 2:1 and 1:1) gave 7 (73%, 35% ee).

2-(Chloromethyl)-6-hydroxy-2H-pyran-3(6H)-one (8). 8 Freshly
distilled acetyl chloride (5.64 g,
72.4 mmol)was added to a solution of 5 (7.96 g, 72.4 mmol) in CH3CN
(20 mL) followed by ammonium
ceric nitrate (1.94 g, 3.56 mmol) in CH3CN (20 mL). After usual
workup and flash chromatography over
silica gel (n-hexane/EA 3:1), product 6 was isolated as a yellow
oil. To a solution of 6 (0.954 g,
6.624 mmol) in PhCH3 (20 mL) was added BH3SMe2 (2M in THF, 0.504 g,
6.624 mmol) in PhCH3
(10 mL), the mixture was stirred for 3 h at r.t. and then quenched
with sat NH4Cl solution. After
usual workup and flash chromatography over silica gel (n-hexane/EA
3:1), pure 7 was isolated as
a pale yellow oil. Compound 7 (0.292 g, 2 mmol) was added to a
solution ofm-CPBA (0.344 g, 2 mmol)
in CH2Cl2 (2 mL) at 0 C and the mixture was stirred fo
