  Chemoenzymatic synthesis of chiral epoxides. Preparation of 4-phenyl-2,3-epoxybutane and 1-phenyl-1,2-epoxypropane

  摘要：

  All the stereoisomers of 4-phenyl-2,3-epoxybutane and 1-phenyl-1,2-epoxypropane (beta-methylstyrene oxide) have been prepared in three steps from 4-phenyl-2-butanone and 1-phenyl-2-propanone or 1-phenyl-1-propanone respectively. The key step is the microbiological reduction of the corresponding haloketones. These results confirm those previously described(1) and demonstrate that the chemoenzymatic synthesis of homochiral 2,3-epoxides is a general method that can be used whatever the starting ketone.

  日期：——

  One-pot stereoselective synthesis of bromohydrins as a useful chiral building block was achieved by the reaction of Grignard reagents with optically active alpha-bromoaldehydes, which were in situ generated by direct asymmetric bromination of aldehydes catalyzed by a binaphthyl-based secondary amine (S)-3.
