Enantioselective Synthesis of Quaternary Stereocenters via Chromium Catalysis.

Yang Xiong1, Guozhu Zhang1.   

Abstract

Asymmetric allylation of aldehydes with γ-disubstituted allyl halides has been achieved in the presence of a sulfonamide/oxazoline chromium complex. A variety of synthetically useful α-homoallylic alcohols with two consecutive stereogenic centers, including one quaternary carbon, can be accessed in a highly diastereoselective and enantioselective manner.
