In our ongoing efforts to promote new synthetic strategies for preparing heterocyclic compounds in this study, we performed reflux reactions with the nanocrystalline-TiO2 on dodecyl-sulfated silica support (NCTDSS) catalyst by using a one-pot method. Finally, high-yield products were synthesized and characterized by using different techniques such as FT-IR, 1H NMR, and 13C NMR. This procedure has several privileges including simple operation, economy, safe environment, short reaction time, and high-yield.}, keywords = {TiO2 nanoparticles,dihydroquinoline,Michael Addition reaction,Ethanol}, url = {https://www.ajgreenchem.com/article_155346.html}, eprint = {https://www.ajgreenchem.com/article_155346_d139a3d765fac280d16c874674350980.pdf} }
