A novel metal-free strategy for oxidative amidation of terminal alkenes by using I2/DMSO for the synthesis of α-ketoamides has been developed. Intriguingly, the use of tert-butylhydroperoxide (TBHP) as co-oxidant can facilitate the synthesis of α-ketoamides at room temperature without any solvent, thereby making it a green protocol. The reaction with primary amines can be easily achieved by using SeO2
通过使用 I2/DMSO 合成 α-酮酰胺,开发了一种新的无金属氧化酰胺化末端烯烃策略。有趣的是,使用叔丁基过氧化氢 (TBHP) 作为助氧化剂可以在室温下促进 α-酮酰胺的合成,无需任何溶剂,从而使其成为一种绿色方案。使用 SeO2 作为氧化剂可以很容易地实现与伯胺的反应。此外,该方法的范围还扩展到苯并噻唑啉和喹唑啉的合成。
