| titleOfInvention | 2-azetidinone derivative and its preparation |
| abstract | NEW MATERIAL:A compound of formula I (R 1 is H, alkoxy, aralkyloxy, di- substituted-amino, etc.; R 2 , 4 are H, alkyl, aralkyl, trialkysilyl; R 3 is alkyl, aryl, aralkyl, heterocyclic group, etc.), and its pharmacologically permissible salt. n EXAMPLE: (4S)-Methyl-α-(4-benzyloxycarbonyl-2-oxoazetidin-1-yl)-α-(phenyl) acetate. n USE: Antibacterial agent having β-lactamase inhibiting activity, and expected to be useful as a remedy of infections diseases together with penicillin, cephalosporin, etc. Also important as an intermediate of bicyclic β-lactam antibiotics. n PROCESS: The compound I wherein R 2 and R 4 are not H is prepared by reacting a compound II (R 2 ' is R 2 except H; R 5 is alkyl, etc.) with halogen, and then alcohol, and hydrolyzing the reaction product. n COPYRIGHT: (C)1979,JPO&Japio |
