selective C–N bond oxidative cleavage method to 3-acylated indoles by Pd-catalyzed oxidative cross coupling of indoles with α-amino carbonyl compounds has been developed; moreover, one-pot synthesis of 3-acylated indoles from 2-ethynylanilines and α-amino carbonyl compounds has also been established. Importantly, the products 3-acylated indoles can be used to construct polyheterocyclic compound, which can
通过钯催化的吲哚与α-氨基羰基化合物的氧化交叉偶联,对3-酰化的吲哚进行了新的选择性的C-N键氧化裂解方法。此外,还建立了由2-乙炔基苯胺和α-氨基羰基化合物一锅合成3-酰化吲哚的方法。重要的是,产物3-酰化的吲哚可用于构建多杂环化合物,其可用作Hg 2+和Fe 3+的有效探针。
