amination of cyclic ether with indole/carbazole derivatives has been accomplished by employing copper(II) chloride/bipy as the catalyst system. In the presence of the di-tert-butyl peroxide oxidant, cyclic ethers such as tetrahydrofuran, 1,4-dioxane, and tetrahydropyran successfully undergo C–H/N–H cross dehydrogenative coupling (CDC) with various carbazole or indole derivatives in good-to-excellent yields
通过使用氯化铜(II)/联吡啶作为催化剂体系,可以简单地将吲哚/咔唑衍生物与环状醚进行α-CH氨基化反应。在存在过氧化二叔丁基氧化剂的情况下,环醚(例如四氢呋喃,1,4-二恶烷和四氢吡喃)可以与各种咔唑或吲哚衍生物良好地成功进行C–H / N–H交叉脱氢偶联(CDC)。到出色的产量。
