Steps:

General experimental procedure for 1,4-DHPs formation catalyzed by Cu-doped ZnO nanocrystalline powder

General procedure: A mixture of benzaldehyde (1 mmol), ethyl acetoacetate or acetyl acetone (2 mmol), ammonium acetate (1 mmol), and 10 mol% of Cu-doped ZnO nanocrystalline powder was refluxed in water (5 ml). The reaction process was monitored by TLC (n-Hexane: EtOAc, 1:1). Upon completion of the transformation, the reaction mixture was cooled to room temperature and extracted with CH₂Cl₂ (3 x 5 ml). The organic layer was washed with brine and water and dried over Na₂SO₄. After evaporation of the solvent, the crude yellow products were purified by crystallization from ethanol to afford 1,4-DHP derivatives in high to excellent yields.
