Asymmetric reduction of β-ketoesters and chiral β-iminoesters: impact of a α-quaternary stereocenter

Abstract

Diastereomeric reduction of nonactivated, hindered β-keto and chiral β-iminoesters are described. The influence of a α-stereocontrolled center on the efficiency and stereoselectivity of the reduction was studied. Reaction conditions were optimized to synthesize β-hydroxy- and β-aminoesters in good yields. In the case of chiral β-iminoesters, influence of matched/mismatched diastereomeric pairs has been assessed.
