comparative purposes, the same two linear tetrasaccharides were prepared by use of MPEG as a soluble polymer support, the yields being 34% and 14%, respectively. An attempted MPEG-supported synthesis of the branched pentasaccharide was unsuccessful. The merits and shortcomings of oligosaccharide syntheses on MPEG are discussed.
通过常规方法分别合成了α-(1-> 6)-和α-(1-> 2)-连接的线性单糖糖苷和支链甘露糖苷[R = CH2(CH2)2CH2Cl]。在溶液中,使用三氯乙酰亚氨酸酯供体,得到的产物的总收率分别为39%,42%和40%。为了比较,通过使用MPEG作为可溶性聚合物载体制备了相同的两种线性四糖,产率分别为34%和14%。MPEG支持的分支五糖合成尝试失败。讨论了在MPEG上合成寡糖的优缺点。
