Abstract
Stereoselective synthesis of some pseudotripeptides incorporating an uncommon bis(alpha-aminoacid) derivative, has been accomplished starting from a L-valine derived chiral synthon. The configuration of the introduced stereogenic centres has been assigned on the basis of 1H NMR spectroscopic data. The geometry of the tripeptides, deduced on the basis of 1H NMR parameters and IR spectra, was confirmed by X-ray crystal investigation.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
