6-(substituted methylene)penems, potent broad spectrum inhibitors of bacterial beta-lactamase. II. Racemic furyl and thienyl derivatives.
A series of racemic 6-(substituted methylene)penems have been prepared. These compounds contain a 5-membered monoheteroaromatic ring at C-8. The antibacterial/synergistic and beta-lactamase inhibitory activities of both E- and Z-isomers and 2-substituted derivatives are compared.
