An efficientmulticomponent synthesis of 3,4-dihydropyrimidin-2[1H]-ones promoted by a heterogeneous copper oxide nanoparticles is presented herein. The copper oxide nanoparticles were synthesized by the electrochemical reduction method and their surface characterizations were examined usingUV-Visible, FT-IR,XRD, SEMEDS and TEMtechniques.This is the clean, efficient and green method for the synthesis of 3,4- dihydropyrimidin-2[1H]–ones derivatives using CuO nanoparticles. The copper oxide nanoparticles catalysts having promising features for the reaction response such as the shortest reaction time, simple work-up procedure, excellent product yields and minimumenvironmental effects.
