The nitrogen-15 nuclear magnetic resonance spectra of some 2-amino-2-deoxj D-hexose drochlorides and 2-acetamido-2-deoxy-D-hexoses and N-benzoyl-D-glucosamine are reported. The differences in chemical shifts for the various hexopyranose structures are discussed in terms of steric, stereoelectronic, and hydrogen-bonding effects. These model compounds were used to study substituent effects related to amino sugar containing polysaccharides and antibiotics.
