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.
Synthesis of <i>N</i>-Aryl and <i>N</i>-Alkyl Anthranilic Acids via S<sub>N</sub>Ar Reaction of Unprotected 2-Fluoro- and 2-Methoxybenzoic Acids by Lithioamides
Substitution of the fluoro or methoxy group in unprotected 2-fluoro- and 2-methoxybenzoic acids to afford N-aryl and N-alkyl anthranilic acids occurs upon reaction with lithioamides under mild conditions in the absence of a metal catalyst.
