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.
