The direct utilization of amines for C–C bond formation without prefunctionalization remains a significant challenge. Herein, we report the base-promoted deaminative coupling of gramines with aminomalaimides under redox-neutral conditions. In this operationally simple reaction, a series of indolmethyl-substituted aminomaleimides that emitted fluorescence were synthesized in good-to-excellent yields
直接利用胺形成 C-C 键而不进行预官能化仍然是一个重大挑战。在此,我们报道了在氧化还原中性条件下碱促进的禾本科胺与
氨基马来
酰亚胺的脱
氨基偶联。在这个操作简单的反应中,合成了一系列发出荧光的
吲哚甲基取代的
氨基马来
酰亚胺,收率非常好。
