Reformatsky reinvented: Highly enantioselectivevinylogous Reformatsky‐type addition has been achieved from the alcoholoxidationlevel with linearregioselectivity through carbon‐bound enolates (see scheme; Boc=tert‐butoxycarbonyl). Complete levels of catalyst‐directed diastereoselectivity are observed in the reaction of an α‐chiral alcohol.

A general procedure for the asymmetric synthesis of highly substituted 1,2-amino alcohols in high yield and diastereoselectivity is described that uses organometallic additions of a wide range of nucleophiles to tert-butylsulfinimines as the key step. The addition of organolithium reagents to these imines follows a modified Davis model. The diastereoselectivity for this reaction depends significantly
