    摘要: A 2-azetidinone of formula (I): ##STR1## wherein R.sub.1 represents an aralkoxy, acyloxy, sulphonyloxy or amino group any of which may be substituted, or hydrogen, hydroxy, alkoxy or azido;R.sub.2 represents an alkyl or aralkyl group either of which may be substituted, or hydrogen;R.sub.3 represents an alkyl, aryl, aralkyl, alkenyl, aralkenyl, alkynyl, aralkynyl, acyl or heterocyclic group any of groups may be substituted;andR.sub.4 represents an alkyl, alkenyl, aryl or aralkyl group any of which may be substituted;or formula (I'): ##STR2## wherein R.sub.1 ' is the same as R.sub.1 above;R.sub.2 ' represents an alkyl, aralkyl or trialkylsilyl group any of which may be substituted, or hydrogen;R.sub.3 ' is the same as R.sub.3 above;andR.sub.4 ' represents an alkyl, aralkyl or trialkylsilyl group any of which may be substituted, or hydrogen; provided that when R.sub.1 ' represents azido or optionally substituted amino, R.sub.2 ' represents hydrogen or CH.sub.2 CCl.sub.3 and R.sub.4 ' represents ##STR3## R.sub.3 ' represents other than ##STR4## 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.
