A new synthetic route to (3R,4S)-3-hydroxy-4-phenylazetidin-2-one as a taxol side chain precursor
摘要:
A new synthetic route to (3R,4S)-3-hydroxy-4-phenylazetidin-2-one an important precursor for the paclitaxel side chain, has been developed using intramolecular cyclization of N-(p-methoxyphenyl) (2S,3R)-2-acetoxy-3-bromo-3-phenylpropionamide which can be easily obtained by catalytic asymmetric dihydroxylation of N-(p-methoxyphenyl)-trans-cinnamide, followed by bromoacetylation.
