In situ Activating Glycosylation of 6-Deoxysugars: Synthesis of O-α-D-Fucosyl-(1→4)-O-α-D-fucosyl-(1→4)-O-α-D-quinovosyl-(1→4)-D-quinovose

The linear tetrasaccharide, α-D-fucopyranosyl-(1→4)-α-D-fucopyranosyl-(1→4)-α-D-quinovopyranosyl-(1→4)-D-quinovopyranose, the sugar cluster of asterosaponin A from the starfish, Asterias amurensis, was synthesized in a convergent manner. We employed an in situ activating glycosylation using 1-OH sug...

Description
Summary:The linear tetrasaccharide, α-D-fucopyranosyl-(1→4)-α-D-fucopyranosyl-(1→4)-α-D-quinovopyranosyl-(1→4)-D-quinovopyranose, the sugar cluster of asterosaponin A from the starfish, Asterias amurensis, was synthesized in a convergent manner. We employed an in situ activating glycosylation using 1-OH sugar derivatives and a system of p-nitrobenzenesulfonyl chloride, silver trifluoromethanesulfonate, and triethylamine as well as a related system.
