title: Synthesis and antibacterial evaluation of 1beta-methyl-2-(5-substituted heterocyclic carbamoyl)pyrrolidin-3-ylthio)carbapenem derivatives.
abstract: The synthesis of a new series of 1beta-methylcarbapenems having a substituted heterocyclic carbamoyl pyrrolidine moiety is described. Their in vitro antibacterial activity against both gram-positive and gram-negative bacteria was tested, and the effect of heterocyclic substituents on the pyrrolidine was investigated. One particular compound (III(d)) having a substituted oxadiazole moiety showed the most potent antibacterial activity.
