Design, synthesis, and evaluation of 2β-alkenyl penam sulfone acids as inhibitors of β-lactamases

A general method for synthesis of 2β-alkenyl penam sulfones has been developed. The new compounds inhibited most of the common types of β- lactamase. The level of activity depended very strongly on the nature of the substituent in the 2β-alkenyl group. Th
