Abstract
Allyl (methyl 2,3,4-tri-O-acetyl-beta-D-glucopyranosyl uronate)-(1-->3)-4,6-O-benzylidene-2-deoxy-2-phthalimido-beta-D-glucopyranoside (4) and benzyl (methyl 2,3,4-tri-O-acetyl-beta-D-glucopyranosyl uronate)-(1-->3)-4,6-O-benzylidene-2-deoxy-2-phthalimido-beta-D-glucopyranoside (5) have been efficiently synthesized by coupling allyl 4,6-O-benzylidene-2-deoxy-2-phthalimido-beta-D-glucopyranoside (2) or benzyl 4,6-O-benzylidene-2-deoxy-2-phthalimido-beta-D-glucopyranoside (3) with methyl (2,3,4-tri-O-acetyl-1-O-trichloroacetimidoyl)-alpha-D-glucopyranuronate (1), respectively, using trimethylsilyl triflate as promoter.
