Notes:
C-Glycopyranosides and C-glycofuranosides were identified using 13C and 1H chemical shift and coupling constant data. Full assignments for all α- and β-anomers were made possible by recourse to carbon-proton chemical shift correlation spectroscopy. Greater steric shielding effects were observed on the carbon atoms in cis-1,2-substituted compounds compared with their trans counterparts. Consistent proton chemical shift differences were also noted in that the anomeric protons resonate at lower field in all cis-1,2-isomers.
