空气和水稳定的碘盐苯基(三氟乙基)碘三限胺在室温下可激活巯基糖苷进行糖基化。武装和解除武装的巯基苷都能以68-97%的产率迅速进行糖基化。反应条件温和,不需要严格排除空气和水分。该方法操作简单,应允许具有有限合成背景的实验人员构建糖苷键。
The air- and water-stable iodonium salt phenyl(trifluoroethyl)iodonium triflimide is shown to activate thioglycosides for glycosylation at room temperature. Both armed and disarmed thioglycosides rapidly undergo glycosylation in 68–97% yield. The reaction conditions are mild and do not require strict exclusion of air and moisture. The operational simplicity of the method should allow experimentalists with a limited synthetic background to construct glycosidic linkages.
