The enantioselective hydrolysis of 3-alkyl- and 3-arylglutaronitriles catalyzed by Rhodococcus sp. AJ270 cells, afforded the corresponding (S)-3-substituted 4-cyanobutanoic acids with low to moderate enantiomeric purities. Additives such as acetone were found to significantly enhance the enantioselectivity of the desymmetrization, giving enantiomeric excesses of up to 95%. The synthetic potential of the homochiral product was also demonstrated by the preparation of optically active (R)- and (S)-4-amino-3-phenylbutanoic acids.
