Six 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 of glycerol and myo-inositol with a chiral bis(dihydropyran).
六个结构单元,六个反应步骤:最近开发的创新方法促进了用于糖基磷脂酰肌醇(GPI)锚定物全合成的复杂低聚糖核心1(此处显示为带有保护基)的汇聚合成。关键因素是通过使用1,2-二缩醛保护基来调节结构单元的反应性,以及用手性双(二氢吡喃)对甘油和肌醇进行去对称化。
