In the present study, we report the catalyst-free direct CH trifluoromethylation of electron-rich indoles in MeOH at 50 °C using Togni’s reagent II as a trifluoromethylation reagent, affording the desired trifluoromethylated compounds in good yields. Furthermore, this new method is demonstrated to be useful for the trifluoromethylation of bioactive molecules melatonin and zolmitriptan, indicating its
在本研究中,我们报道了在 50 °C 下使用 Togni 试剂 II 作为三氟甲基化试剂,在 50 °C 下对富含电子的吲哚进行无催化剂直接 C H 三氟甲基化,以良好的收率提供所需的三氟甲基化化合物。此外,这种新方法被证明可用于生物活性分子褪黑激素和佐米曲普坦的三氟甲基化,表明其在后期三氟甲基化中的应用。
