| titleOfInvention | 2-Azetidinone 4-carboxy derivatives and a process for producing the same |
| abstract | A 2-azetidinone of formula (I): <IMAGE> (I) wherein R1 represents an aralkoxy, acyloxy, sulphonyloxy or amino group any of which may be substituted, or hydrogen, hydroxy, alkoxy or azido; R2 represents an alkyl or aralkyl group either of which may be substituted, or hydrogen; R3 represents an alkyl, aryl, aralkyl, alkenyl, aralkenyl, alkynyl, aralkynyl, acyl or heterocyclic group any of groups may be substituted; and R4 represents an alkyl, alkenyl, aryl or aralkyl group any of which may be substituted; or formula (I'): <IMAGE> (I') wherein R1' is the same as R1 above; R2' represents an alkyl, aralkyl or trialkylsilyl group any of which may be substituted, or hydrogen; R3' is the same as R3 above; and R4' represents an alkyl, aralkyl or trialkylsilyl group any of which may be substituted, or hydrogen; provided that when R1' represents azido or optionally substituted amino, R2' represents hydrogen or CH2CCl3 and R4' represents <IMAGE> R3' represents other than <IMAGE> or a pharmaceutically acceptable salt thereof is disclosed. The derivatives exhibit beta -lactamase inhibiting activity and are thus of interest as anti-bacterial agents, used alone or together with known antibiotic subtances. |
