pyran-2-ones have been synthesized as potential beta-lactamase substrates and/or mechanism-based inhibitors. Substituted o-tyrosine precursors were prepared by the Sörensen method and then heated in vacuo to give the lactones. These compounds are cyclic analogues of aryl phenaceturates which are known to be beta-lactamase substrates. The goal of incorporating the scissile ester group into a lactone
