preparation of chiral tetrahydro-3-benzazepine motifs by catalytic asymmetrichydrogenation. Substrates bearing both 1-aryl and 1-alkyl substituents were smoothly converted to the corresponding hydrogenated product with excellent enantioselectivity (91–99% ee) and in isolated yield (92–99%). The synthetic value of this transformation was demonstrated by a gram-scale hydrogenation and application in the syntheses
