FREMGANGSMAATE VED FREMSTILLING AV 4-ACYLOKSY-2-AZETIDINON-DERIVATER. |
摘要 |
A process for producing 3-[1 min -(R)-hydroxyethyl]-4-acyloxyazetidinone from 3-[1 min -(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 min -(R)-hydroxyethyl]-4-acyloxyazetidinone, an intermediate for synthesizing penems or carbapenems, without using a mercury salt which can cause an environmental hazard. |
