The synthesis and evaluation of 6-alkylidene-2'β-substituted penam sulfones as β-lactamase inhibitors

Penicillin sulfones, which structurally incorporate both a 6-position alkylidene substituent and a 2'β substituent, have been synthesized and evaluated as inhibitors of class C and class A serine β-lactamases. Incorporation of the 2'β-substituent generall
