Résumé 12-Molybdophosphoric acid (MPA) encapsulated in the supercages of dealuminated zeolite Y (DAZY) was used as an efficient and reusable catalyst for green synthesis of biologically active 14-substituted-14-H-dibenzo[a,j] xanthene derivatives via three-component reaction under conventional heating and microwave irradiation conditions. The prepared catalyst, MPA-DAZY, was characterized by infrared spectroscopy (FT-IR), X-ray diffraction (XRD) and elemental analysis techniques. The catalyst, MPA-DAZY, was reused several times without significant loss of its catalytic activity.
