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.

synthetic analogues of O-methylfagaronine which we have synthesized, methoxidine and ethoxidine are active against HIV-1 reversetranscriptase (IC50 values 2.8 microM and 2.4 microM respectively) whereas hydroxidine is inactive. One of the prerequisites for the enzyme inhibitory activity of this class of molecule is the presence of an iminium group--it is well known that a positive charge on a polyaromatic
