亚砜亚胺基团和二氢吡喃酮结构均具有潜在的生物活性, 但目前尚无制备亚砜亚胺基取代的二氢吡喃酮类衍生物的方法. 开发了一种使用磷酸二苯酯作为布朗斯特酸催化剂, 通过亚砜亚胺和二氢吡喃酮的亲核取代反应, 合成亚砜亚胺基取代的二氢吡喃酮类衍生物的新方法, 收率为44%~78%. 该方法条件温和、操作简单且官能团兼容性好, 无需传统方法中使用的贵金属催化剂, 为糖苷类化合物的合成提供了一种新颖高效的策略.

Both sulfoximide and dihydropyranone derivatives have potential bioactivities. However, it is still undisclosed to prepare sulfoximide-substituted dihydropyranone derivatives. Herein, diphenyl phosphate, as Brønsted acid was used to catalyze the nucleophilic substitution reactions of sulfoximides and dihydropyranones to afford sulfoximide substituted dihydropyranone derivatives in 44%~78% yields. This method features mild conditions, simple operation and good functional group compatibility, which avoids using noble metals in traditional manners and provides a novel and effective strategy for the synthesis of glycosides.

Key words: Brønsted acid, sulfoximidie, dihydropyranone, glycoside
