A visible‐light‐mediated synthesis of valuable polycyclic indolizine heterocycles from easily accessed brominated pyridine and enol carbamate derivatives has been developed. This process, which operates at room temperature under irradiation from readily available light sources, does not require the addition of an external photocatalyst. Instead, an investigation into the reaction mechanism indicates
已经开发了一种可见光介导的方法,该方法由易于获得的溴化吡啶和烯醇氨基甲酸酯衍生物合成有价值的多环吲哚嗪杂环。该过程在室温下在容易获得的光源照射下进行,不需要添加外部光催化剂。取而代之的是,对反应机理的研究表明,吲哚嗪产品本身可能以某种方式参与了介导和促进其自身形成的过程。初步研究还表明,这些简单的杂环化合物可能能够促进其他可见光介导的转化。
