  Synthesis, from cellobiose, of a trisaccharide closely related to the GlcNAc→GlcA→GlcN segment of the anti-thrombin-binding sequence of heparin

  摘要：

  O-(2-Deoxy-2-sulfamido-6-O-sulfo-alpha-D-glucopyranosyl)-(1----4)- O-(beta-D- glucopyranosyluronic acid)-(1----4)-1,6-anhydro-2-deoxy-2-sulfamido-6-O-sulfo-beta-D-gl ucopyranose pentasodium salt (14) was synthesized as a heparin-related oligosaccharide. The glycosyl acceptor (derived from cellobiose) and a glycosyl donor, 6-O-acetyl-2-azido-3,4-di-O-benzyl-2-deoxy-alpha-D-glucopyranosyl bromide, were coupled in the presence of mercuric bromide and molecular sieves 4A to afford a 69% yield of fully protected trisaccharide, namely, O-(6-O-acetyl-2-azido-3,4-di-O-benzyl-2-deoxy-alpha-D-glucopyranosyl)-(1 ----4)- O-(methyl 2,3-di-O-benzyl-beta-D-glucopyranosyluronate)-(1----4)-3-O-acetyl- 1,6-anhydro-2 - azido-2-deoxy-beta-D-glucopyranose (10), which was converted into the partially sulfated trisaccharide 14. Compound 10 also underwent acetolysis to afford the glycosyl acetate, for further elongation of the glycosyl chain.
