Process for selective oxidation of primary alcohols of oligosaccharides

The invention relates to a process for the selective oxidation of primary alcohols of oligosaccharides to form the corresponding carboxylic acid derivatives of the alcohols using catalytic amounts of a di-tertiary-alkyl nitroxyl free radical, characterized in that 1,3-dibromo-5,5-dimethylhydantoin or 1,3-dichoro-5,5-dimethylbydantoin is used as oxidant and the reaction is performed in neutral to basic conditions at a pH10. The process of the invention is useful for the production of (partially protected) oligosaccharides comprising carboxylate groups, both intermediates and end products.

Synthesis of heparin partial structures and their binding activities to platelets

A synthetic pentasaccharide corresponding to the antithrombin III-binding region in heparin was also found to bind to human platelets. To identify the platelet-binding site in the pentasaccharide which is expected to be a novel sequence in heparin responsible for its platelet-binding, five partial structures of this particular pentasaccharide were synthesized. In a competitive assay using [3H]-heparin, a trisaccharide, O-(2-deoxy-2-sulfamido-3,6-di-O-sulfo-α-D-glucopyranosyl)- (1→4)-O-(2-O-sulfo-α-L-idopyranosyluronic acid)-(1→4)-2-deoxy-2-sulfamido-6-O-sulfo-α-D-glucopyranose, was concluded to be a high-affinity site for heparin's binding to platelets.
