for the preparation of 3-allyl-2,3-dihydro-2,3′-bisindoles has been developed via homocoupling of N-H indole. Pd-porphyrin-catalyzed allylation of indoles with allylic alcohols in the presence of PBr3 and a base is developed. The reaction involves dimerization at the C3 and C2 positions of the indoles, giving 2-allylated 3-(indolin-2-yl)-1H-indoles in moderate to good yields. 3-(Indolin-2-yl)-1H-indole
通过N -H吲哚的均相偶联,已经开发了制备3-烯丙基-2,3-二氢-2,3'-双吲哚的合适而有效的方法。在PBr 3和碱存在下,Pd卟啉催化吲哚与烯丙基醇的烯丙基化反应。该反应涉及在吲哚的C3和C2位置的二聚作用,以中等至良好的产率得到2-烯丙基化的3-(吲哚-2-基)-1H-吲哚。3-(吲哚啉-2-基)-1 H-吲哚衍生物用作合成药物活性分子的中间体。
