thioglycoside possessing a free hydroxy functionality at the C-4 carbon is prepared, and cycloglycosylation is conducted. In the event, the cycloglycosylation occurs with a ring contraction of the monosaccharide moiety and affords the cyclic furanoside disaccharide. Solution-phase and single-crystal X-ray diffraction structural characterizations permit the features of the macrocycle to be uncovered. The solubilization
