A process for producing optically active (R)-amino compounds which comprises treating an aralkyl alkyl ketone compound (the amino receptor) coexisting with a racemic or (R)-amino compound (the amino donor) with an (R)-specific transaminase produced by a microorganism belonging to the genus Arthrobacter and thus effecting stereoselective transamination. This process makes it possible to facilitate the production in a high yield of optically active (R)-amino compounds, etc., having aryl, etc. at the 1-position which have been difficult to synthesize by the conventional techniques.

Novozyme435 facilitated kinetic resolution of 2-heptylamine was here presented. Methyl methoxyacetate was used as acyl donor. A survey of influencing factors including hydrogen bonding effect, solvent effect, steric effect, temperature and the amount of acyl donor were investigated in detail. At the optimum conditions, the enantiomeric separation was successfully obtained within 8 h at 20 degrees C. and gave high conversion and optical purity of (R)-2-heptylamine, 48.9% and over 99% respectively. The immobilized lipase B was found to be suitable for the enantiomeric separation of aliphatic amines with good recyclability. (C) 2010 Elsevier B.V. All rights reserved.
