نویسنده

چکیده مقاله:

In this work, SO3H-functionalizedphthalimide (SFP) as a SO3H-containing solid acid is prepared by the reaction of phthalimide with chlorosulfonic acid, and characterized by FT-IR, 1H and 13C NMR, Mass, TG, DTG, XRD and SEM. Then, it is utilized as a highly efficient, heterogeneous and green catalyst for the one-pot multi-component condensation of dimedone with arylaldehydes, β-ketoesters and ammonium acetate under solvent-free conditions to afford polyhydroquinolines in excellent yields and in short reaction times.
