  Enantioselective biotransformation of α,α-disubstituted dinitriles to the corresponding 2-cyanoacetamides using Rhodococcus sp. CGMCC 0497

  摘要：

  A new application of nitrile-converting enzymes in the synthesis of optically active alpha,alpha-disubstituted-alpha-cyanoacetamides from alpha,alpha-disubstituted-malononitriles with whole cells of Rhodococcus sp. CGMCC 0497 is described. The products were obtained with enantiomeric excesses of up to >99%, and yields of up to 53%. They are very useful chiral intermediates especially for the synthesis of chiral alpha,alpha-disubstituted amino acids but have never been synthesized directly by chemical or enzymatic methods.
