18 - 140A New Regio- and Stereocontrolled Access to FunctionalizedSilacyclopent-3-enes. — Hydroxy-alkylation of an alkyltitanium inter-mediate derived from diallyldiphenylsilane (I) provides the β-hydroxysilanes(III) with complete diastereocontrol. Following Grubb’s ring closing metathesisgives silacyclopentenes in good overall yield. — (LANDAIS, YANNICK;SURANGE, SHEETAL S.; Tetrahedron Lett. 42 (2001) 4, 581-584; Lab. Chim.Org.
