Dehydrative glycosylation by diethylaminosulfur trifluoride (DAST) - tin(II) trifluoromethanesulfonate-tetrabutylammonium perchlorate - triethylamine system

Dehydrative glycosylation using 2,3,4,6-tetra-O-benzyl-D-glucopyranose was carried out by the use of a condensing reagent system composed of diethylaminosulfur trifluoride (DAST), tin(II) triflate, tetrabutylammonium perchlorate, and triethylamine. Using this system, two tetrasaccharides, O- a-D-glucopyranosyl-(1→4)-O-α-D-glucopyranosyl-(1→3)-Oα-D-glucopyranosyl- (1→4)-D-glucopyranose and O-a-D-glucopyranosyl-(1→3)-O-α-D- glucopyranosyl-(1→4)-O-α-D-glucopyranosyl-(1→4)-D-glucopyranose, were synthesized.
