1H and 13C NMR spectra have been recorded and the nuclear Overhauser enhancements (in D2O), after pre-irradiation of the anomeric protons, have been measured for tri- and tetrasaccharides containing 2,3-disubstituted residues of α-L-rhamnose and the

The syntheses are described of 2,3-di-O-glycosyl derivatives (1-12) of methyl alpha-L-rhamnopyranoside where the glycosyl moieties are variously alpha-L-fucopyranose, beta-L-fucopyranose, beta-D-glucopyranose, alpha-D-mannopyranose, and alpha-L-rhamn

Conformational studies of the branched trisaccharide glycosides X-(1----2)[Y-(1----3)]-alpha-L-Rha-OMe (where X and Y are residues of alpha-L-, beta-L-, alpha-D-, and beta-D-hexopyranoses) were based on 1H- and 13C-n.m.r. data (n.O.e.'s, 13C chemical

On mild acid-catalysed degradation of the lipopolysaccharide from Hafnia alvei O39 followed by gel filtration of Sephadex G-50, the O-specific polysaccharide and three oligosaccharides were obtained, which represent the core substituted with 0-2 O-an

A theoretical conformational analysis of the methyl β-glycosides of cellobiose and maltose was carried out and average values of the coupling constants 3 J C-1,H-4′ and 3 J C-4′,H-1 and optical linkage rotation (Λ) were calculated. It was shown

Conformations of (1→2)-, (1→3)-, and (1→4)-linked disaccharide methyl glycosides involving aldohexopyranose residues have been studied on the basis of the inter-unit n.O.e. and theoretical calculations using atom-atom potential functions. The p

A nuclear Overhauser enhancement in methyl β-maltoside, resulting from pre-irradiation of H-1′ of the non-reducing glucose residue, has been measured and calculated theoretically. Comparison of these data reveals a complicated conformational equil

A computerised approach to the structural analysis of unbranched regular polysaccharides is described, which is based on an evaluation of the 13C-n.m.r. spectra for all possible primary structures within the additive scheme starting from the chemical
