Synthesis of α1-(Cbz-aminoalkyl)-α2-(hydroxyalkyl)phosphinic esters
摘要:
A synthesis of alpha(1)-(Cbz-aminoalkyl)-alpha(2)-(hydroxyalkyl)phosphinic esters was achieved by the 1,2-addition of the appropriate aldehyde to Cbz-protected phosphinic analogues of amino acid esters in the presence of at least three equivalents of trimethylsilyl chloride and NEt3. The complete deprotection of the product esters could be achieved in one step using 35% HBr in acetic acid. (c) 2005 Elsevier Ltd. All rights reserved.

Phosphonic monoesters are prepared in a two—step procedure by DCC—DMAP mediated esterification of phosphonousacids and oxidation of the resulting phosphonous monoester.
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.
