| Abstract: | Protected derivatives of the title carba-trisaccharide 1, and carba-disaccharides 4 and 6 have been synthesised by conventional glycosylation of the precursors 8, 9, or 22 of 5a-carba-alpha-D-mannopyranose with sugar halides. These are carba-sugar analogues of the oligosaccharide chains frequently occurring as structural units in biologically important glycoconjugates, and could be utilised as the building blocks for construction of higher carba-oligosaccharides of biological interest. |
