Abstract

SO3H-functionalized mesoporous silica materials (SO3H-FMSM), as an efficient, mild, recoverable and environmentally friendly heterogeneous mesoporous nanocatalyst, was used to synthesize 2H-indazolo[2,1-b]phthalazine-1,6,11-trione derivatives in a one-pot three-component condensation reaction of 2,3-dihydrophthalazine-1,4-dione, dimedone, and benzaldehyde derivatives under thermal solvent-free (SF) conditions in excellent yields and short reaction times.
