Herein, we report a new, facile, versatile metal-free method for preparation of the various Acridones through an intramolecular carbonylation of 2-(phenylamino)benzoic acid derivatives and phenylboronic acid derivatives as activating agent for activation of carboxylic acid group in intramolecular CC bond formation through Friedel–Crafts reaction. The reaction proceeds under solvent-free conditions
在此,我们报告了一种新的、简便的、通用的无金属方法,通过 2-(苯氨基) 苯甲酸衍生物和苯硼酸衍生物的分子内羰基化制备各种吖啶酮作为活化剂,用于活化分子内 C C中的羧酸基团通过 Friedel–Crafts 反应形成键。该反应在无溶剂条件下进行,具有广泛的官能团,并能以良好到极好的收率快速获得一系列吖啶酮。
