dc.description.abstractA one-step synthesis of 5,7-diaryl-1,5-dihydro-pyrano[2,3-d]pyrimidin-2,4-diones, 3a-c and 5,7-diaryl-2-thioxo-1,2,3,5-tetra­hydropyrano[2,3-d]pyrimidin-4-ones, 3d-g has been achieved by the cyclocondensation of barbituric acid or thiobarbituric acid 1 with arylideneacetophenones, 2a-d in glacial acetic acid in the presence of phosphorous pentoxide. The structures of the compounds 3a-g have been determined by their UV, IR, 1H NMR, 13C NMR, mass spectral data and elemental analyses.en_US
