Abstract
Stereoselective synthesis of some pseudopeptides incorporating 2,6-diamino-4-methylen-1,7-heptanedioic acid residue has been accomplished starting from the L-valine derived chiral synthon. The absolute configuration of new stereocenters was assigned on the basis of 1H-NMR spectra. The geometry of these unnatural tripeptides was deduced on the basis of 1H-NMR parameters and IR spectra. X-ray analysis and conformational studies are also reported.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
