  Synthesis of high enantiomeric purity gem-dihalocyclopropane derivatives from biotransformations of nitriles and amides

  摘要：

  Enantioselective biotransformations of geminally dihalogenated cyclopropanecarbonitriles and amides are described. Both the reaction rate and enantioselectivity of the nitrile hydratase and amidase involved in Rhodococcus sp. AJ270 microbial cells are strongly governed by the nature of gein-disubstituents on the cyclopropane ring; the amidase generally exhibits steric dependence on the substituents while both the steric and electronic factors of the substituents may affect the action of the nitrile hydratase. The match of steric bulkiness of the substituents at 2- with that at 3-positions on the cyclopropane ring benefits the efficient and highly enantioselective reaction. Coupled with facile chemical transformations, biocatalytic transformations of nitrile and amide supply an effective synthesis of optically active 2,2-disubstitued-3-phenylcyclopropanecarboxylic acid and amide in both enantiomeric forms.

  the cells were strongly determined by the nature of the halogen substituent. The synthetic utility of the biocatalytic process was illustrated by an efficient and multi-gram scale biotransformation and synthesis of enantiopure 2,2-dichloro-3-phenylcyclopropanecarboxylic acid and amide in both enantiomeric forms.
