New glycolipids that feature a carbohydrate/triazole/lipid hybrid architecture were readily produced by a combined multicomponent/click approach. The process comprises the use of the Ugi four-component reaction to construct double-lipidic scaffolds that have either alkyne or azide functionalities followed by conjugation to mono- and trisaccharides through a CuI-catalyzed 1,3-dipolar cycloaddition (click)
具有碳水化合物/三唑/脂质混合结构的新糖脂很容易通过组合多组分/点击方法生产。该过程包括使用 Ugi 四组分反应构建具有炔烃或叠氮化物官能团的双脂支架,然后通过 CuI 催化的 1,3-偶极环加成(点击)过程与单糖和三糖结合。整个过程的高化学效率和可行性为这种独特的 Ugi/click 糖脂类库的快速创建和生物筛选提供了新的机会。进行动态核磁共振实验以评估与这些化合物中顺式/反式酰胺键的异构化相关的活化自由能。
