An expeditious metal free C-3 alkylation of indoles and its NIS-mediated deviation to indolo[2,3-b]quinolines is reported. This protocol, executed in aqueous HFIP has broad substrate scope and is well inclined towards the ideas of sustainable chemistry. Applications of these strategies in accessing bioactive natural products like vibrindole, norcryptotakeine, neocryptolepine and indenoindolone scaffolds
报道了吲哚的快速无金属 C-3 烷基化及其 NIS 介导的吲哚并[2,3- b ]喹啉的偏离。该协议在水性 HFIP 中执行,具有广泛的底物范围,并且非常倾向于可持续化学的理念。这些策略在获取生物活性天然产物(如 vibrindole、norcryptotakeine、neocryptolepine 和茚并吲哚酮支架)方面的应用也已得到证实。
