Methyl O-(2-acetamido-2-deoxy-tri-O-acetyl-β-D-glucopyranosyl)-(1→1)-tri-O-acetyl-α-D-glucopyranuronate (II) was synthesized by the condensation of methyl 2, 3, 4, -tri-O-acetyl-α-D-glucopyranuronate (IV) with acetochloroglucosamine (V) in the presence of mercuric cyanide in nitromethane and similarly O-(methyl tri-O-acetyl-β-D-glucopyranosyluronate)-(1→6)-2-acetamido-2-deoxy-tri-O-acetyl-β-D-glucopyranose (III) was prepared by the condensation of 2-acetamido-2-deoxy-1, 3, 4-tri-O-acetyl-α-D-glucopyranose (VI) with methyl 1-bromo-tri-O-acetyl-α-D-glucopyranuronate (I) in the presence of silver oxide in chloroform.
