Regioselectively substituted esters of oligo- and polysaccharides and a method of producing them |
摘要 |
A regioselectively substituted member selected from the group consisting of oligo-saccharide ester and polysaccharide ester is disclosed. The ester has a partial average degree of substitution AS at the C2 position of its anhydroglucose unit of at least 90% relative to the total AS. Also disclosed is a method of producing the regioselectively substituted ester. The method entails reacting in the presence of a catalyst a dissolved or a highly swollen oligo-saccharide or polysaccharide with an esterification reagent.
