Easy does it: A wide range of N‐fused indole skeletons, which are core structures of many biologically potent molecules, are successfully furnished by a niobium‐catalyzed C(sp3)H insertion reaction (see picture). The precursors are readily prepared by a palladium‐catalyzed amination reaction of bromotrifluorotoluenes with cyclic amines.
简单易行:铌催化的C(sp 3)H插入反应成功地提供了多种N稠合的吲哚骨架,这些骨架是许多具有生物活性的分子的核心结构(参见图片)。通过溴三氟甲苯与环胺的钯催化胺化反应可轻松制备前体。
