    摘要： A method for preparing aromatic carboxylic acid derivatives by nucleophilic aromatic substitution, involves reacting an aromatic carboxylic acid derivative supporting only one carboxyl function, or one of the salts thereof, the carboxylic acid derivative supporting, orthogonally to the carboxyl function, a leaving group which is a fluorine or chlorine atom or an alkoxy group, chiral or otherwise and, in the latter case, preferably a methoxy group; the carboxylic acid derivative being substituted by at least one electro-attractive group other than the leaving group, preferably by a fluorine atom, with a MNu reagent, wherein M is a metal and Nu an optionally chiral nucleophile, the nucleophilic aromatic substitution reaction being carried out without a catalyst and without a step of protecting/unprotecting the acid function of the initial compound, the method being selective in that the reaction leads to the formation of ketone derivatives in a very minority fashion during the reaction.
