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.
