Abstract

Melamine trisulfonic acid (MTSA) as an efficient heterogeneous catalyst has been used for the one-pot preparation of triazolo[1,2-a]indazole-1,3,8-trione and 2H-indazolo[2,1-b]phthalazine-1,6,11-trione derivatives by the three-component condensation reaction of URAZOLEs or PHTHALHYDRAZIDE, DIMEDONE or 1,3-cyclohexanedione, and ALDEHYDEs under solvent-free conditions in good to excellent yields and short reaction times.
