CHEMOENZYMATIC OLIGOSACCHARIDE SYNTHESIS ON A SOLUBLE POLYMERIC CARRIER

[摘要] A facile and efficient method for the chemical and enzymatic syntheses of oligosaccharides using a new type of soluble polymeric sugar acceptor substrate is described. The water soluble glycopolymers having N-acetyl-D-glucosamine (GlcNAc) branches derived from a p-substituted benzyl glycosides were galactosylated with bovine milk galactosyl transferase. The flexible GlcNAc branches of the polymer chains allow quantitative galactosylation and subsequent hydrogenolysis proceeded smoothly to release the desired N-acetyl-lactosamine from the polymer support in high yield.
