Development of a rapid, room-temperature dynamic kinetic resolution for efficient asymmetric synthesis of α-aryl amino acids

Abstract

equation presented A rapid, highly efficient and general dynamic kinetic resolution (DKR) of racemic α-aryl UNCAs with the dual-function catalysis of modified cinchona alkaloid was accomplished at room temperature. This DKR led to the development of a highly enantioselective catalytic method for the practical synthesis of a wide range of α-aryl and α-heteroaryl amino acids in 89-92% ee and 86-95% yield from racemic UNCAs.
