Diastereo‐ and Enantioselective Hydrogenation of α‐Amino‐β‐Keto Ester Hydrochlorides Catalyzed by an Iridium Complex with MeO‐BIPHEP and NaBAr

: Catalytic Cycle and Five‐Membered Chelation Mechanism of Asymmetric Hydrogenation
Ir‐catalyzed asymmetric hydrogenation of α‐amino‐β‐keto ester hydrochlorides is described. This reaction proceeds through a dynamic kinetic resolution to produce anti‐β‐hydroxy‐α‐amino acid esters in a high diastereo‐ and enantioselective manner. Mechanistic studies have revealed that this unique asymmetric hydrogenation proceeds through reduction of the ketone moiety via the five‐membered transition state
