Asymmetric SE' reactions of (E)-and (Z)-γ-substituted-α,β- unsaturated aldehydes have been studied for the stereocontrolled preparation of nonracemic alcohols. Mild exchange reactions of allylic stannanes provide access to chiral 1,3-bis-(tolylsulfonyl)-4

A match made in heaven: All the possible stereoisomers of α,ω-functionalized 2,4-dimethylpentane dyad and 2,4,6-tri- methylheptane triad chirons (see picture; A and B, respectively; FG = functional group, PG = protecting group) can be reached by using a c
High ?-Face Selectivity in Anti Aldol Reactions of E-Enol Borinates from Chiral Alkoxymethyl Ketones: Stereocontrolled Synthesis of a C24-C32 Polyol Subunit of Rapamycin

Using (c-C6H11)2BCl/Et3N, the aldol reactions of the α-chiral alkoxymethyl ketones 5 and 6 with achiral aldehydes gives the 1,2-anti-2,4-anti adducts 7 and 8 in 83-95 percent yield with >/= 95 percent diastereoselectivity.This novel aldol reaction was applied to a concise and highly stereocontrolled synthesis of the C24-C32 subunit 9 of rapamycin (10).
