electrochemical selenylation reaction of chalcones with diselenides for the synthesis of 3-selenylazaflavanones and 3-selenylflavanones at room temperature was reported. The method proceeded under mild conditions, exhibited a broad substrate scope, and provided the selenylated products in moderate to excellent yields with high regio- and stereoselectivity. The reaction could also be readily scaled
在此,报道了查耳酮与二硒化物在室温下进行无氧化剂和无金属的电化学硒化反应,用于合成 3-硒基氮杂黄酮和 3-硒基黄烷酮。该方法在温和的条件下进行,表现出广泛的底物范围,并以中等至优异的产率提供具有高区域和立体选择性的硒化产物。该反应还可以很容易地以高效率扩大规模。通过控制实验进行的详细机理研究表明,硒基自由基可能参与了这种电化学转化。
