Palladium/<scp>l</scp>-Proline-Catalyzed Enantioselective α-Arylative Desymmetrization of Cyclohexanones

Abstract

A highly enantioselective palladium/l-proline-catalyzed α-arylative desymmetrization of cyclohexanones was developed. The new strategy for α-arylation reaction led to a series of optically active morphan derivatives bearing α-carbonyl tertiary stereocenters in good yields with excellent enantioselectivities (up to 99% ee).
