manifold with various 1,3-dicarbonyl compounds and halogenated N-allyl ynamides was accomplished under alkaline reaction conditions, facilitating the synthesis of differently sized N-heterocycles. A large array of products was prepared to demonstrate the selective synthesis of N-heterocycles of different ring sizes (5-, 6-, and 7-membered rings) via cobalt catalysis. The reaction has broad substrate
在碱性反应条件下完成了具有各种 1,3-二羰基化合物和卤代N-烯丙基酰胺的三苯基膦连接的钴催化环化歧管,促进了不同大小的N-杂环的合成。准备了大量的产品来证明通过钴催化选择性合成不同环大小(5、6 和 7 元环)的N-杂环。该反应具有广泛的底物范围和广泛的官能团。
