Here we report a glucosylation strategy mediated by ZnI2, a cheap and mild Lewis acid, for the highly stereoselective construction of 1,2-cis-O-glycosidic linkages using easily accessible and common 4,6-O-tethered glucosyl donors. The versatility and effectiveness of the α-glucosylation strategy were demonstrated successfully with various acceptors, including complex alcohols. This approach demonstrates
在这里,我们报告了一种由廉价和温和的路易斯酸 ZnI 2介导的糖基化策略,用于使用易于获得和常见的 4,6 - O-束缚葡萄糖基供体高度立体选择性地构建 1,2-顺式-O-糖苷键。α-葡糖基化策略的多功能性和有效性已通过各种受体(包括复合醇)成功证明。这种方法证明了模块化合成具有线性和支链骨架结构的各种 α-葡聚糖的可行性。
