A novel and efficient copper-catalyzed tandem oxidative cyclization/1,2-amino migration of readily available enamino esters for the synthesis of substituted pyrroles has been developed. In this reaction, one C–N bond was cleaved, and two new C–N bonds and one C(sp2)–C(sp2) bond were constructed in one pot. This catalytic system has the obvious advantages of mild reaction conditions and the use of oxygen
已经开发出新颖且有效的铜催化串联氧化环化/容易获得的烯氨基酯的1,2-氨基迁移用于合成取代的吡咯。在该反应中,一个C–N键被裂解,并且在一个锅中构建了两个新的C–N键和一个C(sp 2)–C(sp 2)键。该催化体系具有温和的反应条件和使用氧气作为氧化剂的明显优点。该反应可耐受各种官能团,并且是一种可靠的方法,可以以高收率直接合成有价值的氨基甲基取代的吡咯。
