Novel pyrrolo[3,2-d]pyrimidine derivatives have been synthesized by an efficient and regioselective Fe (III)-mediated iodocyclization method starting from a commercially available uracil compound. Here, iron has a dual role in the iodocyclization process by acting as a Lewis acid which promotes the release of I+ cation from iodine by removing iodide ion, and also as an oxidant which again generates
新型吡咯并 [3,2- d ] 嘧啶衍生物已通过有效且区域选择性的 Fe (III) 介导的碘环化方法从市售尿嘧啶化合物开始合成。在此,铁在碘环化过程中具有双重作用,既作为路易斯酸通过去除碘离子促进碘释放 I +阳离子,又作为氧化剂从碘离子再次生成碘参与催化反应循环。
