One-step, One-pot and Solvent-free Synthesis of 2H-Indazolo[2,1-b]phthalazine-1,6,11-trione Derivatives in the Presence of MCM-41-SO3H Nanocatalyst

MCM-41-SO3H, as an efficient, mild, recoverable and environmentally friendly heterogeneous mesoporousnanocatalyst has been used to synthesize 2H-indazolo[2,1-b]phthalazine-1,6,11-trione derivatives in a one-pot threecomponentcondensation reaction of phthalhydrazide, dimedone, and benzaldehyde derivatives under solvent-free (SF)conditions in excellent yields and short reaction times.
