visible‐light‐induced trifluoromethylation of isonitrile‐substituted indole derivatives has been developed from the reaction of isonitrile‐substituted indoles with Togni II reagent, affording 1‐(trifluoromethyl)‐4,9‐dihydro‐3H‐pyrido[3,4‐b]indoles in moderate to good yields. The further transformations to β‐carboline derivatives and a harmacine derivative have been performed, demonstrating the potential synthetic
的可见光诱导的异腈基取代的吲哚衍生物的三氟甲基化已经从与TOGNI II试剂异腈取代的吲哚的反应研制,得到1-(三氟甲基)-4,9-二氢-3- ħ -吡啶并[3,4 ‐b]吲哚产量中等至良好。已经进行了向β-咔啉衍生物和harmacine衍生物的进一步转化,证明了该方法的潜在合成效用。一项初步的生物学研究表明,含有CF 3的harmine类似物可显着刺激胰高血糖素样肽1(GLP-1)的分泌,表明糖尿病的治疗有所改善。
