A new scheme of repetitive and controlled peptide synthesis offers two advantages compared to the usual methods of synthesis : two steps only are used for the prolongation of a peptide chain with an aminoacid residue and the risk of racemisation is minimized. The two postulated steps are verified particularly by the rearrangement, in an alkaline alcoholic medium, of phosphordiamides 1 incorporating
