One-pot synthesis of benzo[<em>c</em>]acridine derivatives via the three-component condensation reaction of aromatic aldehydes, 1-naphtylamine, and dimedone using sulfonic acid functionalized SBA-15 (SBA-Pr-SO<sub>3</sub>H) as nanoporous acid catalyst under solvent-free conditions was studied. This reaction is an efficient, green and  environmentally friendly procedure.

The antimony(III) chloride impregnated on alumina efficiently catalyses a one-pot, three-component condensation reaction among an aldehyde, a β-ketoester, and urea or thiourea to afford the corresponding dihydropyrimidinones in good to excellent yields. The reactions are probed in microwave (MW), ultrasonic, and thermal conditions and the best results are found using MW under solvent-free conditions.Key words: Biginelli dihydropyrimidinones synthesis, SbCl3–Al2O3, MW, sonication, solid supported.
