A convenient one-pot method for the synthesis of 4-arylquinolin-2(1H)-ones and 4-arylcoumarins has been described. The successive Heck reaction on substituted 2-iodoaniline and 2-iodophenol catalyzed by a Pd/nickel ferrite catalyst followed by in situ cyclization was the key step. The scope of this methodology was extended to the synthesis of bioactive 3-alkenyl derivatives of 4-arylquinolin-2(1H)-ones.
已描述了一种合成4-芳基喹啉-2(1H)-酮和4-芳基香豆素的便捷一锅法。由Pd/镍铁氧体催化的取代2-碘苯胺和2-碘酚的连续Heck反应,随后进行原位环化是关键步骤。这种方法的范围已扩展到合成生物活性的4-芳基喹啉-2(1H)-酮的3-烯基衍生物。
