A new route providing access to 2-arylindoles has been developed. The synthesis consists of a tin-mediated tandem radical cyclization of appropriate precursors to form 2,3-disubstituted dihydroindoles, which in turn are oxidized to yield the corresponding 2-arylindoles. The reactions proceed smoothly under microwave irradiation, furnishing the desired products in good yields.
已经开发出一条新的路线,用于合成2-芳基
吲哚。该合成方法包括对适当的前体进行
锡介导的串联自由基环化反应,形成2,3-二取代二氢
吲哚,然后将其氧化,得到相应的2-芳基
吲哚。在微波辐射下,反应顺利进行,产率很高。
