A new practical method for regioselective nucleophilic aromatic alkylation of ortho- or para-methoxy-substituted aromatic esters with Grignard reagents
A new practical method for the regioselective nucleophilic aromaticalkylation of o- or p-methoxy-substituted aromatic carboxylic acids via their triethylcarbinyl ester derivatives by conducting the reactions with alkyl/aryl Grignard reagents in toluene has been developed.
