1, 4-Diazabicyclo [2.2.2] octane (DABCO) was employed as a catalyst for one-pot synthesis of pyrano[2,3-d] pyrimidinone derivatives and MWNT- pyrimidinones from condensation reactions of aromatic aldehydes, malononitrile and thiobarbituric acid and MWNT-COCl . This method delivers the advantages of a simple method, environment friendly procedure, mild reaction conditions and high returns. The materials were characterized by Fourier transform infrared spectroscopy, nuclear magnetic resonance, mass spectroscopy, elemental analysis, scanning electron microscopy and Thermogravimetric analysis.
