  Nitrile biotransformations for the synthesis of enantiomerically enriched β2-, and β3-hydroxy and -alkoxy acids and amides, a dramatic O-substituent effect of the substrates on enantioselectivity

  摘要：

  Rhodococcus erythropolis AJ270, a nitrile hydratase/amidase-containing microbial whole cell catalyst, is able to catalyze the hydrolysis of a number of P-hydroxy and beta-alkoxy nitriles under very mild conditions. Both the efficiency and enantio selectivity of the biocatalysis. however, were strongly dependent upon the structures of both nitrile and amide substrates. When biotransformations of racemic 3-hydroxy-3-phenylpropionitrile and 2-hydroxymethyl-3-phenylpropionitrile gave low enantioselectivity, their O-methylated isomers underwent highly efficient and enantio selective biocatalytic reactions to afford highly enantioenriched beta(2)- and beta(3)-hydroxy amide and acid derivatives in excellent yield. The study has provided an example of simple and very convenient substrate engineering method to increase the enantioselectivity of the biocatalytic reaction. (C) 2008 Elsevier Ltd.
