An efficient Cu-catalyzed direct C1−H difluoromethylation of pyrrolo[1,2-a]quinoxalines with BrCF2CO2Et or BrCF2CONEt2 has been reported, providing to a series of difluoromethylated pyrrolo[1,2-a]quinoxalines with generally good yields. This approach features good compatibility with substituents, broad substrate scope, and gram-scale synthesis. The further transformations of the products are also examined
已经报道了用 BrCF 2 CO 2 Et 或 BrCF 2 CONEt 2对吡咯并[1,2- a ]喹喔啉进行有效的铜催化直接 C1-H 二氟甲基化,提供了一系列二氟甲基化吡咯并[1,2- a ]喹喔啉产量普遍良好。该方法具有与取代基的良好相容性、广泛的底物范围和克级合成。还检查了产品的进一步转化。
