Various metals (Cu, Fe, Al and Zn) have been successfully employed in the MCR of aryl carbaldehydes, ethyl acetoacetate and urea to give respective dihydropyrimidinones in good to excellent yields. The catalysts in these reactions are easily recovered and used many times without losing its catalytic activity. The products were duly characterized through their spectral analysis.
