  Synthesis of novel cyano-cyclitols and their stereoselective biotransformation catalyzed by Rhodococcus erythropolis A4

  摘要：

  A variety of novel cyano-cyclitols possessing complex stereochemistry have been synthesized. These compounds were subjected to the biocatalyzed hydrolysis of their nitrile groups. The bacterial strain Rhodococcus erythropolis A4, expressing a nitrile hydratase/amidase bienzymatic system, was able to recognize (1R,25,35,4R)/(15,2R,3R,4.5)-1-cyano-2,3,4-trihydroxy-cyclohex-5-ene and trans-3-cyanocyclohexa-3,5-diene-1,2-diol, and to catalyze their transformations into the corresponding amides and acids. The kinetic and stereochemical trends of these biotransformations, a rare example of the enantiorecognition of a rigid bulky aliphatic substrate, are discussed. (C) 2010 Elsevier Ltd.
