Asymmetric allylation of aldehydes with γ-disubstituted allyl halides in the presence of a sulfonamide/oxazoline chromium complex provides various synthetically useful α-homoallylic alcohols with two consecutive stereogenic centers, including one quaternary carbon, in a highly diastereoselective and enantioselective manner.
