Nuclear Overhauser effects and conformations of branched trisaccharide methyl beta-glycosides that contain a 3,4-disubstituted galactose residue.
N.O.e. data after pre-irradiation of the anomeric protons and the 3JC,H values associated with the glycosidic linkages for a series of methyl beta-glycosides of trisaccharides that contain 3,4-disubstituted galactose residues have been measured. On the basis of the experimental results and theoretical calculations, it was shown that one preferred conformer (less than 90%) was present for each trisaccharide derivative.
