One-pot synthesis of 3,4-dihydropyrimidin-2(1H)-ones catalyzed by SO3H@imineZCMNPs as a novel, efficient and reusable acidic nanocatalyst under solvent-free conditions

The synthesis of 3,4-dihydropyrimidin-2(1 H )-one derivatives was accomplished via a three-component reaction in the presence of SO 3 H@imineZCMNPs as a novel, environment friendly, and reusable heterogeneous magnetic nanocatalyst under solvent-free conditions at 90 °C.
