Palladium and silver cocatalyzed the asymmetric transfer hydrogenation of azabenzonorbornadienes with tertiary amines to give the corresponding ring‐opening products in high yields with good to excellent enantioselectivities. (R)‐2,2′‐Bis(diphenylphosphino)‐1,1′‐binaphthyl [(R)‐BINAP] and para‐methoxybenzoic acid were used as the chiral ligand and additive, respectively, in the reported protocol.
