A novel amine oxidase (AO)/imine reductase (IRED) system was developed for the deracemization of racemic amines. By combining (R)-6-hydroxy-d-nicotine oxidase (6-HDNO) with an (R)IRED, a panel of racemic 2-substituted piperidines and pyrrolidines were deracemized to yield the (S)-amines in high yields and enantiomeric excess values. Other N-heterocycles were deracemized with monoamine oxidase (MAO-N) or 6-HDNO in combination with ammonia borane, which allowed comparison of the two enzyme deracemization approaches with that involving a chemical reducing agent.
