Stereoselective Epimerizations of Glycosyl Thiols

Glycosyl thiols are widely used in stereoselective S-glycoside synthesis. Their epimerization from 1,2-trans to 1,2-cis thiols (e.g., equatorial to axial epimerization in thioglucopyranose) was attained using TiCl4, while SnCl4 promoted their axial-to-equatorial epimerization. The method included application for stereoselective β-d-manno- and β-l-rhamnopyranosyl thiol formation. Complex formation explains the equatorial preference when using SnCl4, whereas TiCl4 can shift the equilibrium toward the 1,2-cis thiol via 1,3-oxathiolane formation.

Studies on the conformational flexibility of α-l-rhamnose-containing oligosaccharides using 13C-site-specific labeling, NMR spectroscopy and molecular simulations: Implications for the three-dimensional structure of bacterial rhamnan polysaccha

Bacterial polysaccharides are comprised of a variety of monosaccharides, l-rhamnose (6-deoxy-l-mannose) being one of them. This sugar is often part of α-(1 → 2)- and/or α-(1 → 3)-linkages and we have therefore studied the disaccharide α-l-Rhap-(1 → 2)-α-l

The synthesis of methyl-3-O-(β-D-fucopyranosyl)-β-D-quinovopyranoside and its 3′-O-, 2,3′-di-O-, and 2′,3′-di-O-methyl derivatives

Methyl-3-O-(β-D-fucopyranosyl)-β-D-quinovopyranoside and its 3′-O-, 2,3′-di-O-, and 2′,3′-di-O-methyl derivatives were obtained by the regioselective Helferich glycosylation of methyl-2-O-benzyl-β-D-quinovopyranoside with the 2,3,4-tri-O-benzoyl-α-D-fucopyranosyl bromide followed by the methylation with diazomethane or methyl iodide.

Synthesis of Oligosaccharides Corresponding to the Common Polysaccharide Antigen of Group B Streptococci

To facilitate mapping of the immunodominant region of the common polysaccharide antigen of group B streptococci, tetrasaccharide 1-O--α-rhamnopyranosyl>-D-glucitol (2) was synthesized in a stepwise fasion
