  First Gram-Scale Synthesis of a Heparin-Related Dodecasaccharide

  摘要：

  The first example of a gram-scale synthesis of a structurally defined, heparin-related dodecasaccharide is reported. An iterative 14-step process using an iduronate donor disaccharide delivers > 1g quantities of the dodecasaccharide sequence [GlcNS-IdoA2S](6)-OMe in 15% overall yield from the reducing terminal disaccharide, a 2 orders of magnitude increase in scale for access to synthetic heparanoid dodecasaccharide mimetics. The synthesis also delivers multigram amounts of the protected oligosaccharides from tetra- through to dodecasaccharide.
