Abstract
A simple and efficient decarboxylative radical addition/cyclization strategy was developed, by which a wide range of benzimidazo[2,1-a]isoquinoline-6(5H)-ones were prepared in one-pot via reaction of functionalized 2-arylbenzoimidazoles and carboxylic acids in the presence of K2S2O8/AgNO3 under mild reaction conditions.
摘要
开发了一种简单高效的脱羧基自由基加成/环化策略，通过该策略，在温和的反应条件下，在 K2S2O8/AgNO3 的存在下，通过官能化的 2-芳基苯并咪唑和羧酸一锅反应，可制备得到广泛的苯并咪唑并[2,1-a]异喹啉-6(5H)-酮。
