Ureido 2-deoxy-␤-D-glucopyranosides with seven different amino acid ester residues were studied by means of IR and 1 H NMR spectroscopy. The H-D exchange rates increase in the order L-Val <L-Leu <L-Ala < Gly for both NH protons; however, the exchange rate at N-1-H (linked to the glucopyranoside) is

Ureido sugars with seven various L-amino acid ester residues were studied by means of 'H, "C, and "N NMR in solution and 13C CP MAS in the solid state. The chemical shifts and coupling constants in the 'H, t3C, and "N NMR spectra indicated that the replacement of one amino acid residue by another ha
