Amines in which the amino group is on a secondary carbon atom which is chirally substituted can be enantiomerically enriched by the action of an omega-amino acid transaminase which has the property of preferentially converting one of the two chiral forms to a ketone. The process also can be used to stereoselectively synthesize one chiral form from ketones substantially to the exclusion of the other.
