The Staudinger reaction of unprotected azido-peptides with silylated phosphinicacids and esters on the solid support offers a straightforward acid-free entry to different phosphonamidate peptide esters or acids under mild conditions in high purity and yield.
Abstract Herein we report a facilesynthesis of esters of bis‐α‐aminoalkylphosphinic acids obtained by an addition of Cbz‐protected phosphinic analogues of amino acid methyl esters to an appropriate imine in refluxing benzene. Complete deprotection of the esters could be achieved in one step by the action of 30% HBr in acetic acid.

OO-Di-trimethylsilyl esters of alpha-N-benzyloxycarbonylaminoalkylphosphinates (III) undergo triethylamine catalyzed addition to isothiocyanates to give after hydrolysis, a series of new alpha-aminoalkyl-(Nsubstituted)thiocarbamoyl-phosphinates. Thiocarbamoyl-phosphinate moiety can be included in the structures of the metalloproteinase inhibitors as the zinc-binding group and the new compounds reported here are good inhibitors of important aminopeptidase N(CD13) with IC(50) in range of 10.56- 0.25 mu M.
