An unprecedented route for the synthesis of 3,3'-biindoles is developed. Both symmetrical and unsymmetrical 3,3'-bi-indoles could be generated by this method. Mild conditions, high yields of the products, and environmentally acceptable reagent are the merits of the procedure.
开发了一种前所未有的合成 3,3'-二吲哚的路线。这种方法可以生成对称和不对称的 3,3'-双吲哚。温和的条件、产品的高产率和环境可接受的试剂是该程序的优点。
