An efficient enantioselective synthesis of pseudotripeptides, incorporating 2,6-diamino-4-methylene-1,7-heptandioic acid residue, has been accomplished starting from the glycine derived chiral synthon (obtained from L-valine). The absolute configuration of new stereocenters was assigned on the basis of 1H-NMR spectra. The geometry was deduced on the basis of 1H-NMR parameters and IR spectra
