  Enzymatic desymmetrization of 3-alkyl- and 3-arylglutaronitriles, a simple and convenient approach to optically active 4-amino-3-phenylbutanoic acids

  摘要：

  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. (C) 2002 Elsevier Science Ltd.

  3-arylglutaronitriles catalyzed by Rhodococcus sp. AJ270 cells proceeded regiospecifically and enantioselectively to produce S-(+)-3-aryl-4-cyanobutyric acids in high enantiomeric excess. Convenient chemoenzymatic syntheses of optically active R-(−)-4-amino-3-phenylbutyric acid and 4R-(−)-4-phenyltetrahydropyran-2-one are described.
