| Abstract: | Using methyl triflate as promoter, methyl O-(2,3,4,6-tetra-O-benzyl-α-D-glucopyranosyl)-(1→4)-(methyl 2,3-di-O-benzoyl-β-D-glucopyranosyluronate) and methyl O-(2,3,4,6-tetra-O-benzyl-β-D-galacto-pyranosyl)-(1→-4)-O-(2,3,6-tri-O-benzyl-α-D-glucopyranosyl)-1(1→4)-(methyl 2,3-di-O-benzoyl-β-D-glucopyranosyluronate) have been synthesised. Removal of protecting groups gave the di- and trisaccharide in the form of their methyl ester methyl glycoside related to the antigen of Klebsiella type 16. |
