The preparation of phosphono peptides containing a phosphonamidate bond
摘要:
The synthesis of phosphono peptides containing phosphonamidate bond by means of phosphorylation of amino acid esters with N-protected aminoalkylphosphonochloridates, is accompanied by the formation of an unidentified side-product. The factors influencing this reaction were studied in some detail.

N-protected α-aminoalkylphosphinic acids by the reaction of N,N′-benzylidene- or N,N′-alkylidenebiscarbamates, trifluoroaceticanhydride and the corresponding alkylphosphonous acids in methylene chloride or toluene is described. The results obtained confirm the earlier proposed mechanism for amidoalkylation of hydrophosphorylic compounds involving an Arbuzov-type reaction step.

A general and highly convenient method for the synthesis of N-protected α-aminophosphinic acids, suitable for side chain elongation either from N-, P-, or C- termini to form a variety of phosphinic peptides, has been developed. The desired phosphinic acids were obtained in moderate to satisfactory yield by a three-component condensation reaction of benzyl carbamate, an aldehyde, and an alkylphosphonous
Dipeptides which contain phosphorus and their pharmaceutical use and preparation are disclosed. The compounds have dehydropeptidase (DHP) enzyme inhibitor activity.
