Complementary enantiospecific syntheses of conduritol E epoxides from halobenzenes
摘要:
Microbial oxidation of chlorobenzene or bromobenzene gave diols (3), which were converted in stereoselective and chemoselective sequences involving epoxidation/osmylation steps and reduction to the enantiomers of (-)- or (+)-conduritol E epoxide (4).
