An efficient and highly enantioselective method for the preparation of (R)-tolterodine is described. The synthesis was performed by CuH-catalyzed asymmetric conjugate reduction of a β,β-diaryl-substituted unsaturated nitrile as a key step, which is prepared by a stereoselective hydroarylation of alkynenitrile with aryl boronic acid. The synthesis was accomplished without employing the protection−deprotection
