Novel method for peptide synthesis using an N-[N'-nitroso-(R')carbamoyl]amino acid as the starting compound. The compound is separated into N¿2?, R'OH and N-carboxyanhydride of formula (II). The compound (II) together with an amino acid or peptide with at least one free .alpha.-amino function is introduced into a reactive medium to obtain a dipeptide or a higher peptide than the added peptide.

La présente invention concerne un nouveau procédé de synthèse peptidique, utilisant un N-[N'-nitroso-(R')carbamoyl]aminoacide comme composé de départ. On décompose ce composé en N2, R'OH et N-carboxyanhydride de formule (II). On réalise ensuite une réaction d'addition entre le composé (II) et un acide aminé ou un peptide ayant au moins une fonction .alpha.-aminé libre, en vue d'obtenir un dipeptide ou un peptide de rang supérieur par rapport au peptide additionné.
