摘要：
3-(2-(Thioacylthio)alkanamido)-1,4-(cyclo-(1''carboxy)alkylenethio)azetidin-2-one derivatives possessing antibacterial activity are produced by the reaction of a carbodithioic acid 1-carboxy(lower)alkyl ester and a 3-amino-1,4(cyclo(1''-carboxy)alkylenethio)azetidin-2-one derivative in the presence of a condensing agent.
