Enantioselective synthesesO 0031 Cu(I)-Catalyzed Stereospecific Coupling Reactions of Enantioenriched α-Stan-

nylated Benzyl Carbamates and Their Application. — A series of enantioenriched α-stannylated benzyl carbamates is treated with allyl bromides and acid chlorides to give coupling products with stereospecificities of up to 98%. The intramolecular vari-ant allows the synthesis of enantioenriched indanols and tetralins such as (XIII) and (XIV). — (LANGE, H.; FROEHLICH, R.; HOPPE*, D.; Tetrahedron 64 (2008) 38, 9123-9135; Org.-Chem.
