Abstract An efficient approach for the one-pot synthesis of 2,3-diarylbenzofurans via sequential iodocyclization and Pd-catalyzed Suzuki coupling reaction of 2-alkynylanisoles with boronic acids in water is reported. The protocol utilizes water as the solvent and there is no need to isolate the intermediate 3-iodine-2-arylbenzofurans, which exemplifies the ideal of green chemistry. Various 2-alkynylanisoles
摘要 本文报道了一种通过顺序碘环化和 Pd 催化 2-炔基苯甲醚与硼酸在水中的 Suzuki 偶联反应一锅法合成 2,3-二芳基苯并呋喃的有效方法。该协议以水为溶剂,无需分离中间体 3-碘-2-芳基苯并呋喃,这体现了绿色化学的理想。各种 2-炔基苯甲醚和硼酸可以参与反应,以中等至良好的收率提供一系列用于药物发现的 2,3-二芳基苯并呋喃。图形概要
