  Synthesis of galactofuranosyl-containing oligosaccharides corresponding to the glycosylinositolphospholipid of Trypanosomacruzi

  摘要：

  The oligosaccharide beta-D-Ga1f-(1-->3)-alpha-D-Manp-(1-->2)-[beta-D-Ga1f-(1-->3)]-alpha-D-Manp-(1-->2)-alpha-D-Manp corresponds to the terminal end of the glycosylinositolphospholipid oligosaccharide of the protozoan Trypanosoma cruzi, the causative agent of Chagas' disease. Syntheses of methyl or ethylthio glycosides of the terminal disaccharide, trisaccharide, tetrasaccharide, and pentasaccharide corresponding to this structure are described. These syntheses employ the selective activation of a phenyl 1-selenogalactofuranoside or a phenyl 1-selenomannopyranoside donor over ethyl 1-thioglycoside accepters with NIS-TfOH.

  building blocks, six reaction steps: The recently developed innovative methodology facilitated the convergent synthesis of the complex oligosaccharide core 1 (shown here with protecting groups) for the total synthesis of a glycosylphosphatidylinositol (GPI) anchor. The key factors are the tuning of the reactivity of the building blocks by using 1,2-diacetal protecting groups and the desymmetrization

  六个基本组成部分，六个反应步骤：最新开发的创新方法促进了复杂寡糖核心1（此处显示有保护基团）的收敛合成，从而实现了糖基磷脂酰肌醇（GPI）锚的全部合成。关键因素是通过使用1,2-二缩醛保护基调节结构单元的反应性，以及甘油和肌醇与手性双（二氢吡喃）的脱对称性。
