Abstract
A novel protocol for Rh(iii)-catalyzed switchable C-H acylmethylation and annulation of 2,2'-bipyridine derivatives with sulfoxonium ylides is reported. This protocol provides a facile approach to synthesize structurally diverse acylmethylated 2,2'-bipyridine derivatives and acyl pyrido[2,3-a]indolizines with a broad range of functional group tolerance.
摘要
本文报道了一种新型的 Rh(iii)-催化的 2,2'-联吡啶衍生物与亚砜叶立德的可切换 C-H 酰甲基化和环化反应的方案。该方案为合成结构多样的酰甲基化 2,2'-联吡啶衍生物和酰基吡啶并[2,3-a]吲哚嗪提供了一种简便的方法，具有广泛的官能团容忍度。
