A new solid phase method for the synthesis of complex oligosaccharides is described. The method involves attachment to phenolic polystyrene of the first carbohydrate unit, through its anomeric position and via a photolabile linker, using dimethylthiomethylsulfonium triflate as an activator. Reiteration of the glycosidation process allows stereocontrolled growth of linear or branched oligosaccharides
描述了一种用于合成复杂寡糖的新固相方法。该方法包括使用二甲基硫代甲基锍三氟甲磺酸盐作为活化剂,通过其异头位置并通过光不稳定接头连接到第一个碳水化合物单元的酚聚苯乙烯。糖苷化过程的重复允许线性或支化寡糖以高产率立体控制生长。通过光解有效地实现从树脂的裂解。该方法在总制备中的应用。描述了七糖植物抗毒素诱导剂 (HPE) 的结构。
