| titleOfInvention |
Azetidinone derivative and production thereof |
| abstract |
NEW MATERIAL:An azetidinone derivative shown by the formula I (R 1 and R 2 are H or protecting group; R 3 is alkyl or H). n EXAMPLE: 1-Benzyl-3-(1-hydroxyethyl)-4-(1-methoxycarbonylethenyl)-2-azetidinone. n USE: A raw material for an intermediate of 1β-methylcarbapenem antibiotic to be expected as a β-lactam antibiotic of IV generation. n PREPARATION: An ethynylazetidinone shown by the formula II is subjected to hydroxyalkoxycarbonylation in the presence of a metal of group VIII or a compound of the metal, an alcohol and carbon monoxide and optionally hydrolyzed, to give an azetidinone derivative shown by the formula I. n COPYRIGHT: (C)1987,JPO&Japio |
