The present invention relates to a method of preparing optically active amines and chiral amines prepared thereby. The method includes reacting an amine compound, a metal catalyst, a biocatalyst including a lipase, and an acyl donor compound in an organic solvent to obtain a chiral amide compound, and then hydrolyzing the chiral amide compound to obtain a chiral amine.

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%)
