A highly efficient asymmetrichydrogenation of azepine/oxazepine-type seven-member cyclic imine hydrochlorides was successfully developed using Rh/bisphosphine-thiourea ligand ZhaoPhos, affording various chiral seven-member cyclic amines with full conversions, high yields, and excellent enantioselectivities (up to 96% yield, >99% ee). Additionally, this asymmetrichydrogenation can proceed well on
catalyze the enantioselectivehydrogenation of diverse seven‐membered C=N‐containing heterocyclic compounds (eleven examples; up to 97 % ee). The P‐OP ligand L3, which incorporates an ortho‐diphenyl substituted octahydrobinol phosphite fragment, provided the highest enantioselectivities in the hydrogenation of most of the heterocyclic compounds studied. The observed stereoselection was rationalized by means
