Abstract An easy and convenient method is reported for the synthesis of polyhydroquinoline derivatives in solvent-free conditions under microwave irradiation in the presence of magnetic nickel ferrite nanoparticles (NiFe2O4 MNPs) as a catalyst. Excellent yields (82–94 %), facile work-up, achieving high purity of products via simple recrystallization, and short reaction times (2–5 min) are some advantages
