Abstract NMR data (chemical shifts, NOEs, coupling constants and variable temperature experiments), FT-IR data and MM2 ∗ molecular mechanics calculations have allowed us to demonstrate that 3-amido-1,6-anhydro-3-deoxy-β-D-glucopyranose acts as a hydroxyl-based interaction unit and provides conformational control of self-recognition processes by ...

An efficient synthesis of triazolo-carbohydrate mimetics and their conformational analysis
Organic & Biomolecular Chemistry, 2008A chemical library of 1,2,3-triazole fused carbohydrate mimetics was constructed. To synthesize enantiomerically pure mimetics, we developed a stereo- or diastereodivergent synthetic route from D-glucose, D-mannose and D-galactose as chiral sources. In this synthesis, an In(OTf)(3)-catalyzed tandem azidation-1,3-dipolar cycloaddition reaction of 1,1 ...

▪ Abstract For nuclear magnetic resonance determinations of the conformation of oligosaccharides in solution, simple molecular mechanics calculations and nuclear Overhauser enhancement measurements are adequate for small oligosaccharides that adopt single, relatively rigid conformations. Polysaccharides and larger or more flexible

Conformational parameters of the carbohydrate moieties of α-arabinonucleosides
Carbohydrate Research, 1981Abstract The conformations of the sugar moieties of a number of α- d - and - l -arabino-furanosyl nucleosides in solution have been investigated, largely with the aid of a statistical procedure developed for this purpose. The overall results demonstrated the existence, for a broad range of analogs, of a two-state, conformational equilibrium, N⇌S (or
