چکیده مقاله :
Pills of Mefenamic acid were employed as effective catalysts in the three component reaction of aromatic aldehydes, malononitrile, as well as 4-hydroxycoumarin or barbituric acid in aqueous solution, using reflux conditions in order to synthesize derivatives of dihydropyrano[2,3-c]chromene and pyrano[2,3-d]pyrimidine, correspondingly. Among the benefits of this technique, higher efficiency, shorter reaction time, along with better reaction indices could be mentioned.
