approach to fused [1,2-a]indoles 25, 26 and 27 is described; the synthesis is based on a novel intramolecular radical cyclization reaction involving ipso-substitution using sulfone, sulfide and sulfoxide substituted indoles. Some more general aspects of scope and limitation of the process are presented including vinyl and aryl radical cyclizations of 29 and 30; investigations using substituted indoline
描述了一种熔融[1,2- a ]吲哚25、26和27的新方法;该合成是基于一种新颖的分子内自由基环化反应,该反应涉及使用砜,硫化物和亚砜取代的吲哚进行ipso取代。提出了方法范围和限制的一些更一般的方面,包括29和30的乙烯基和芳基自由基环化。还讨论了使用取代的二氢吲哚和苯胺衍生物35和37的研究。
