A practical method for the regiocontrolled synthesis of substituted quinoline-4-carboxylic acids is described. Solubility differences between the product quinoline regioisomers enable their facile separation, thus avoiding any challenging chromatographic purifications and allowing access to highly substituted quinoline compounds in three steps from commercially available anilines.
描述了一种用于区域控制合成取代喹啉-4-羧酸的实用方法。产品喹啉区域异构体之间的溶解度差异使其易于分离,从而避免了任何具有挑战性的色谱纯化,并允许通过三个步骤从市售苯胺中获得高度取代的喹啉化合物。
