1H and 13C N.m.r. studies and conformational analysis have been performed on eight 1,4-linked disaccharides in which the glycosidic linkages are in different stereochemical environments.The disaccharide glycosides have been divided into two groups, one containing α-DD-, β-LD-, and β-DL- glycosides, and one containing β-DD-, α-LD-, and α-DL-glycosides with typical chemical shift differences for each group.The conformational analysis, using the HSEA-approach, indicates a number of proton-oxygen and proton-proton interactions resulting in downfield and upfield shifts of the proton signals, respectively.The 13C n.m.r. glycosylation shifts obtained have been used to simulate spectra of polysaccharides containing 1,4-linkages.
