Several bicyclic pyrazolidinones were synthesized as γ-lactam analogs of the β-lactam antibiotics. Two of these compounds exhibited antibacterial activity, and thus constitute a new class of antibacterial agents.

The 1, 3-dipolar cycloadditionreaction of pyrazolidinium ylide with substituted vinylsulfones was studied. Elimination of benzenesulfinic acid from the resulting cycloadducts gave rise to bicyclic pyrazolidinones . The (E)-olefin isomers were found to undergo cycloaddition in a highly regioselective fashion. These pyrazolidinones represent the nuclei of an exciting new class of potent antibacterial
