説明
Abstract Solid-state polycondensation of natural aldopentoses and 6-deoxyaldohexoses was found to take place in the presence of H3PO4 (5 mol%) at 100–110 °C under a N2 flow, giving highly branched polysaccharide (Conv. 47–81%, Mw=2700–12 000, Mn=1400–2900); the reaction mixtures were powdery throughout the polymerization. The product polysaccharide was per-O-methylated and subjected to the structure analyses. The acid-hydrolysis, which gave a variety of the partially O-methylated monosaccharides, suggested that the product polysaccharides proved to have highly branched structures consisting of both furanose and pyranose units. MALDI-TOF mass analysis revealed that the 1,4-anhydride terminal unit was formed and participated to the polymerization.
