Production of azetidinone derivative |
| abstract |
PURPOSE: To provide a method for producing an azetidinone derivative which is an important intermediate for synthesizing β-lactam-based antimicrobial agents. n CONSTITUTION: The subject method is to produce (3R,4R)-4-acetoxy-3-[(R)-1- hydroxyethyl]-2-azetidinone characterized as follows. (3R,4R)-4-Acetoxy-3-[(R)-1- formyloxyethyl]-2-azetidinone is treated in a solvent in the presence of an enzymic source having the activity of positional and chemical selective hydrolysis or ester interchange of the aforementioned compound. n COPYRIGHT: (C)1992,JPO&Japio |
