1,2,3-Triazole derivatives of salicylic acid

This paper describes the preparation of 1,2,3-triazole derivatives of salicylic acid from the methyl 4-azidosalicylate, by 1,3-dipolar cycloaddition reactions to beta-ketoesters, beta-ketoamides, beta-diketones and to symmetrical or asymmetrical alkynes. Other derivatives were obtained by hydrolysis and decarboxylation reactions. Some compounds were evaluated for antiinflammatory activity by an in vitro test based upon the inhibition of the cyclooxygenase enzyme, but they generally showed a weak activity.
