|Abstract:||Dipyridine cobalt chloride is used as an alternative conventional Lewis acid catalyst in the Pechmann condensation of isoxazolyl phenols with β-ketoesters leading to the formation of isoxazolyl coumarins. The method is simple, cost-effective and at ambient temperature gives good yields.|
