Copper-catalyzed stereospecific oxidative dehydrocouplings of P(O)H bonds with amines under air took place effi-ciently at room temperature to afford the corresponding amidophosphorus compounds in high yields. Mechanistic studies showed that this dehydroc

N-Sulfonylphosphoramidates have been synthesized to investigate the electrostatic requirements for binding to alkaline phosphatase. Alkyl- and aryl N-benzylated sulfonamides were phosphorylated with bromophosphates or synthesized via phosphoramidite chemistry in moderate yields (44-77%.) The resulting tribenzylated N-sulfonylphosphoramidates may be deprotected in one step to give the free acids in quantitative yields. Physical data of N-sulfonylphosphoramidates, including pKa's and stability toward hydrolysis, were determined. Inhibition data suggests that AP does not bind trianionic N-sulfonylphosphoramidates better than dianionic N-sulfonylphosphoramidates, although N-sulfonylphosphoramidates are bound tighter than N-phenylphosphoramidate. kcat for the hydrolysis of N-sulfonylphosphoramidates by bovine and E. coli alkaline phosphatases is 10-60% that of p-nitrophenyl phosphate.
