Copper-catalyzed radical cascade cyclization for synthesis of CF<sub>3</sub>-containing tetracyclic benzimidazo[2,1-<i>a</i>]iso-quinolin-6(5<i>H</i>)-ones
copper-catalyzed radical cascade carbocyclization reaction with 2-arylbenzoimidazoles and a Togni reagent was realized. Structurally diverse CF3-containing tetracyclic core benzimidazo[2,1-a]isoquinoline-6(5H)-ones were obtained in moderate to good yields. The wide substrate scope, good functional group tolerance, and ease of scale-up of this method are expected to promote its potential applications in pharmacy
在此,实现了与2-芳基苯并咪唑和Togni试剂的一般的铜催化的自由基级联碳环化反应。以中等至良好的产率获得了结构多样的含CF 3的四环核苯并咪唑并[2,1 - a ]异喹啉-6(5 H)-。预期该方法的广泛底物范围,良好的官能团耐受性和易于放大的规模将促进其在药学和生物技术中的潜在应用。
