Abstract A catalytic, practical, efficient procedure for the synthesis of 5-benzylidene-1,3-dimethylpyrimidine-2,4,6(1H,3H,5H)-trione and pyrano[2,3-d] pyrimidine diones at roomtemperature was developed using L-Proline nitrate ionic liquid under ultrasonic irradiation. The L-Proline nitrate is homogeneous and green catalyst easy to prepare by mixing L-Proline and nitric acid possess excellent catalytic
