Abstract

AbstractA highly enantioselective method for the synthesis of β‐hydroxy esters via reductive aldol reaction of acrylates with aryl and heteroaromatic ketones is described. In situ generated catalyst composed of zinc acetate and chiral diamine afforded enantioenriched tertiary alcohols in high yields and with excellent enantioselectivity (up to 91% ee). This is also the first successful application of the zinc hydride reagent in stereoselective reductive aldol reactions of ketones.magnified image
