NMR studies have been performed on the methyl glycosides of some (1-->6)-linked disaccharides. Observed J5,6pro-R and J5,6pro-S values indicate that, for the 6-substituted D-gluco- and D-galacto-pyranosides, the rotamer distribution around the C-5-C-6 bond deviates somewhat from that observed for th
## One -and two-dimensional NMR spectroscopy were employed to determine the conformation of 2,3,4,6,2',3'-hexa-O-acetyl-4-O-a-D-glucopyranosyl-1',6'-anhydro-~-D-glucop~anose in acetone-d, solution. Inter-residue interproton distances, H-1-H-4' and H-1-H-Q', determined by 2D NOE experiments are com
Double-quantum heteronuclear local field NMR is performed on a sample of a 13C2-labeled disaccharide, in which the two 13C spins are located on opposite sides of the glycosidic linkage. The evolution of the double-quantum coherences is found to be consistent with the solid-state conformation of the
