Abstract: | A new dialdose dianhydride derivative was obtained from an acid hydrolyzate of the water-soluble polysaccharide of wobaku wood by successive treatment with methanolic hydrogen chloride and acetic anhydride-pyridine. This compound was determined to be the 1,2′:1′,2-dianhydride of 3,4-di-O-acetyl-β-l-rhamnopyranose and methyl 3,4-di-O-acetyl-α-d-galactopyranuronate. |
