Abstract
The synthesis of a new series of 1$\beta$-methylcarbapenems having 5-($\alpha,\beta$-disubstituted ethyl)pyrrolidine moiety is described. Their in vitro antibacterial activities against both Gram-positive and Gram-negative bacteria were tested and the effect of substituents on the pyrrolidine ring was investigated. A particular compound (VIh) having $\alpha$-hydroxy-$\beta$-piperazinylethyl substituted moiety showed the most potent activity.
