The SRN1 reaction has been used as a powerful tool for the synthesis of heterocycles, and only a few studies about photoinduced intramolecular cyclization to generate a new C–O bond by a radical pathway have been reported. This work introduces two strategies for the synthesis of substituted dibenzofurans by electron transfer (eT) reactions. The first one is a three-step process that comprises bromination
S RN 1反应已被用作合成杂环的有力工具,并且仅报道了少数有关通过自由基途径光诱导分子内环化以生成新的C-O键的研究。这项工作介绍了两种通过电子转移(eT)反应合成取代的二苯并呋喃的策略。第一个是三步过程,其中包括溴化o-芳基苯酚,Suzuki-Miyaura交叉偶联和光诱导的环化反应,以获得上述产物。第二种是无金属工艺,不需要任何光催化剂。测试了不同的溶剂,收率范围从低到中等。在两种方法之间建立了比较,表明第二种方法最适合合成二苯并呋喃。
