Methods have been reported for the preparation of ω-functionalized alkyl maltoside and glycoside detergents via a simple and inexpensive synthetic route. The key step was stannic chloride-mediated glycosylation of long-chain alcohols or thiols with maltose octaacetate at 0 or –10°C, respectively, within a very short time (isolated yield 17–44%), which provided more than 98% β-selectivity.
已经报道了通过简单且廉价的合成路线制备ω-官能化烷基麦芽糖苷和糖苷去污剂的方法。关键步骤是氯化锡介导的长链醇或硫醇与麦芽糖八乙酸酯分别在 0 或 –10°C 下在很短的时间内进行糖基化(分离产率 17–44%),提供超过 98% 的 β -选择性。
