A range of aryl substituted spirocycles containing the indole moiety have been assembled through Claisen rearrangement, Fischer indole cyclization, ring-closing metathesis and the Suzuki–Miyaura cross-coupling reactions. Some of these molecules contain either a spirocyclic system or an indeno[1,2-b]indole framework, which is present in diverse bioactive targets. Here, we have used simple and readily
通过克莱森重排,费歇尔吲哚环化,闭环易位和铃木-宫浦交叉偶联反应,已组装了一系列含有吲哚部分的芳基取代螺环。这些分子中的一些包含螺环系统或茚并[1,2- b ]吲哚骨架,它们存在于各种生物活性靶标中。在这里,我们使用了简单易用的起始材料来生成螺环化合物库,其中螺环化合物的结构具有吲哚单元。
