synthetic route could be readily scaled up to gram quantity without difficulty. Mechanistic studies have revealed that in situ formed selenium electrophile species may be the key intermediate for the selenocyclization process.
已经开发了一种新颖的无金属一锅方案,该方案通过简单的2-乙烯基苯胺通过分子内环化/硒化反应合成潜在的生物活性分子3-硒基吲哚,具有中等至良好的收率,因此代表了它是通往多种取代模式的便捷途径围绕吲哚核。反应在宽的底物范围和优异的官能团耐受性下顺利进行。而且,本合成路线可以容易地按比例放大至克量而没有困难。机理研究表明,原位形成的硒亲电物种可能是硒环化过程的关键中间体。
