摘要:
A process for producing 3-[1′-(R)-hydroxyethyl]-4-acyloxyazetidinone from 3-[1′-(R)-hydroxyethyl]-4-alkyl (or aryl) thioazetidinone using a copper salt of aliphatic or aromatic carboxylic acid is disclosed. The process is an effective route for producing 3-[1′-(R)-hydroxyethyl]-4-acyloxyazetidinone, an intermediate for synthesizing penems or carbapenems, without using a mercury salt which can cause an environmental hazard.
