Under very mild conditions, the Rhodococcus sp. AJ270-catalysed biotransformation of arylglycine nitriles 1, prepared easily from the reaction of substituted benzaldehydes, ammonium chloride and potassium cyanide, proceeded efficiently to produce optically active d-arylglycine amides 2 and l-arylglycines 3 in excellent yields with enantiomeric excesses higher than 99%.

incorporating a suitable carbonyl reductase within an optimal pH range coinciding with the ω-transaminase to facilitate transamination, this innovative process makes it possible to remove coproducts via asymmetric reduction with the assistance of carbonyl reductase. Two chiral compounds are obtained by the addition of the desired chiral amines. The carbonyl reductase has three distinct functions: providing extra

enantioselectivity was also discussed in terms of steric and electronic effects. Coupled with chemical hydrolysis of D-(-)-alpha-phenylglycine amide, biotransformation of DL-phenylglycine nitrile was applied in practical scale to produce both D- and L-phenylglycines in high optical purity.
