Abstract: An environmentally benign approach to the selective synthesis of novel compounds 5,8-diaryl-5,7-dihydro-1H-pyrano[2,3-d:6,5-d']dipyrimidine-2,4,6-triones under microwave irradiation (MWI) using inorganic solid supports is described. The reaction time decreases from hours to minutes along with yield enhancement. In addition, catalytic role of various inorganic supports is studied, and acidic alumina is found to be the best in terms of selectivity.
