Resumo1,6:3,4-Dianhydro-2-O-tosyl-β-D-galactopyranose was converted into the triacetate of methyl 4-O-methyl-D-glucuronate via 1,6:2,3-dianhydro-4-O-methyl-β-D-mannopyranose and 4-O-methyl-D-glucose. The 1,2-(methyl orthoacetate) of methyl 3-O-acetyl-4-O-methyl-D-glucuronate was prepared and used for the glycosylation of 1,2:3,4-di-O-isopropylidene-α-D-galactopyranose. The aldobiouronic acid derivative thus obtained was converted into the known amide of methyl 6-O-(4-O-methyl-β-D-glucopyranosyluronic acid)-α-D-galactopyranoside.
