A-L-Rhamnopyranosyl- -D-glucose

Naturally occurring hydroxyanthraquinone 3-glycosides of 6-0- 3-D-xylo-pyranosyl-D-glucose (primeverose) and 6-0-a-L-rhamnopyranosyl-D-glucose (rutinose) have been prepared by use of the acetylated glycosyl halides. ... 

O -a-L-Rhamnopyranosyl-D-glucose, R-44 6- O - p-L-Rhamnopyranosyl-D-glucose, R-45 a-L-Rhamnopyranosyl-(l ->4)-D-glucuronic acid, R-46 6- O -a-L-Rhamnopyranosyl-D-mannose, R-48... 

In the area of deoxyhexose-based disaccharides, the isomalto di- and tri-saccharide compounds devoid of oxygen at C-2 have been produced by standard methods. 3-O-a-D-Fucopyranosyl-D-glucose has been synthesized with 0-2 of the fucose unit carrying a methyl group,and 6-O-a-L-rhamnopyranosyl-D-glucose has been prepared as a fully substituted glycosyl thiocyanate and used in the synthesis of a rhamnoglucan polysaccharide. ... 

The preparation of methyl jS-L-rhamnopyranoside and the synthesis of (I -> 2)-linked disaccharides containing non-reducing residues of 6-deoxy-D-glucopyranoseand of 3-0-a-L-rhamnopyranosyl-D-glucose have been noted in Chapter 3.
