The cycloacylation of aniline derivatives to 4-quinolones in the presence of Eaton's reagent is described. This high-yielding methodology is applicable to a wide variety of functionalized anilines and requires milder conditions than those traditionally employed. This cyclization protocol is used to prepare a host of heterocycles and bis-quinolones and is characterized by relatively low reaction temperature and ease of product isolation.
本文描述了在伊顿试剂存在下，苯胺衍生物环酰化生成4-喹诺酮的反应。这种高产率方法适用于多种功能化苯胺，且所需条件比传统方法更为温和。该环化反应方案用于制备一系列杂环化合物和双喹诺酮，其特点是反应温度相对较低且产物易于分离。
