Knoevenagel‐Michael‐cyclocondensation Tandem Reaction of Malononitrile, Various Aldehydes and Dimedone Catalyzed by Sulfonic Acid Functionalized Pyridinium Chloride as a New Ionic Liquid and Catalyst
Journal of the Chinese Chemical Society Vol. 62, No. 5, 398–403
چکیده
Abstract New ionic liquid sulfonic acid functionalized pyridinium chloride [Pyridine–SO3H]Cl was used for the synthesis of tetrahydrobenzo[b]pyran derivatives by the one‐pot three component condensation reaction of various aldehydes, dimedone and malononitrile at 95 ºC under solvent‐free conditions.
