The enantioselective reduction of C=N bonds constitutes an effective strategy for the production of chiral amines. Herein, manganese-catalyzed asym. transfer hydrogenation of hydrazones by employing a readily available chiral aminobenzimidazole manganese(I) complex under mild conditions was reported. The present protocol allows for the enantioselective transfer hydrogenation of a wide range of arylalkyl, dialkyl and diaryl hydrazones, providing the desired chiral hydrazines in excellent yields and enantioselectivities (65 examples, up to 99.9% ee). Of note, the current method is compatible with the challenging diaryl hydrazones without the requirement of an ortho-substitution on the Ph ring. A preliminary study of the mechanism suggests that a manganese-hydride pathway is involved, and the high enantiocontrol of the reaction is attributed to a π-π stacking interaction between substrate and catalyst.
