Melamine trisulfonic acid (MTSA) as an efficient catalyst for the synthesis of triazolo[1,2-a]indazole-triones and some 2H-indazolo[2,1-b]phthalazine-triones
Iranian journal of catalysis Vol. 3, No. 4, 211–220
چکیده
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.
