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(G
PI)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。
