An efficient Hantzsch four-component condensation reaction for the synthesis of polyhydroquinoline derivatives was found to proceed in the presence of iron (III) phosphate in ethanol under reflux condition. The method is really simple and environmentally benign. The keys features of this protocol are the use of a heterogeneous and reusable catalyst, high yields of products, nontoxic solvent, and short reaction times from the principles of green chemistry point of view.
