Iodonium ion treatment of 1,2-unsaturated octa-O-methylmaltotriose having a sole hydroxy group at the 4″-position results in dimerization of the trisaccharide derivative with simultaneous cyclization, giving a fully methylated cyclohexasaccharide consisting of four α-D-glucopyranosyl residues and two 2-deoxy-2-iodo-α-D-mannopyranosyl residues.
