Four phosphonamidates were synthesized as potential beta-lactamase inhibitors. Three were methanephosphonamidates [CH3PO2-NHR/Ar, where R/Ar = 4-methoxybenzyl (3a), phenyl (3b), and m-nitrophenyl (3c)], while the fourth, PhCH2OCONHCH2PO2-NHPh (2a), also contained a beta-lactamase active site-directed amido side chain.
