The complete conversion of racemic aminoacid amides to optically active aminoacid derivatives was accomplished via lipase/palladium-catalyzed dynamickineticresolution (DKR). In the DKR, a lipase catalyzes the selective acylation of l-substrate in the presence of acyl donor while unreacted d-substrate is isomerized by a Pd nanocatalyst to l-substrate. The DKR reactions provided good yields (80−98%)
