Abstract
The building block synthon, 1-(4-(1,3-diphenyl-1H-pyrazol-4-yl)-6-methyl-2-thioxo-1,2,3,4-tetrahydropyrimidin-5-yl)ethan-1-one was efficiently synthesized by Biginelli reaction of 1,3-diphenyl-1H-pyrazole-4-carbaldehdye, acetylacetone, and thiourea and submitted to react with ethyl chloroacetate and chloroacetyl chloride under different conditions to afford some N-heterocycles integrated with pyrazole scaffold. Hydrazinolysis of the pyrimidinethione was studied under different conditions. The insecticidal activity for these compounds, DFT calculations, and docking were run and discussed. Some of them exhibited 100% mortality against Nilaparvata lugens and Mythimna separata.
