Method for preparing carboxylic acid derivatives by aromatic nucleophilic substitution, in which a carboxylic acid derivative having a single carboxyl functional group, or one of the salts thereof, the carboxylic acid derivative having, in the ortho position of the carboxyl functional group, a leaving group, which is preferably an atom of fluorine or of chlorine or an alkoxy group, chiral or not, preferably a methoxy group, the carboxylic acid derivative not being substituted by an electro attractive group other than the leaving group if any; is reacted with a reactant MNu, where M is a metal and Nu is a nucleophile, chiral or not, the aromatic nucleophilic substitution reaction being carried out without a catalyst and without a step of protecting/deprotecting the acid functional group of the starting compound.
通过芳香亲核取代法制备羧酸衍生物的方法,其中羧酸衍生物具有单个羧基官能团,或其盐之一,该羧酸衍生物在羧基官能团的邻位具有一个离去基团,该离去基团优选为氟原子或氯原子或烷氧基,手性或非手性,优选为甲氧基,如果有的话,该羧酸衍生物未被电子亲合基团取代;与反应物MNu发生反应,其中M为金属,Nu为亲核试剂,手性或非手性,芳香亲核取代反应在无催化剂和无保护/去保护起始化合物的酸官能团的步骤的情况下进行。
