A concise synthesis of furo[3,2-c]coumarins catalyzed by nanocrystalline ZnZr4(PO4)6 ceramics under microwave irradiation

چکیده مقاله

A simple and concise method catalyzed by nanocrystalline ZnZr4(PO4)6 ceramics has been reported for the synthesis of a series of trans-2-benzoyl-3-(aryl)- 2H-furo[3,2-c]chromen-4(3H)-ones using a multicomponent reaction of 2,4′-dibromoacetophenone, benzaldehydes and 4-hydroxycoumarin under microwave irradiation. This method provides several advantages including easy workup, excellent yields, short reaction times, using of microwave as clean method, recoverability of the catalyst and little catalyst loading.
