Intramolecular N-arylation of pyrrole and indole carboxamides and carboxylates linked with a pendant haloarene by Cu-catalyzed reactions to synthesize pyrrole and indole quinoxalinone and oxazinone derivatives is reported. The ring closure reactions were carried out by conventional heating and MW irradiation. The use of conventional heating affords moderate to good yields of the quinoxalinone and oxazinone
分子内N-芳基化吡咯 和吲哚羧酰胺和羧酸盐与侧链卤代芳烃通过铜催化反应连接起来合成 吡咯 和 吲哚喹喔啉酮并报道了恶嗪酮衍生物。闭环反应通过常规加热和MW辐射进行。使用常规加热可获得中等至良好的喹喔啉酮和恶嗪酮衍生物的收率(34%至72%),而使用MW加热可获得最佳结果(41%至99%)。
