Abstract:	A number of 5, 7-diaryl-1,5-dihydro (or 1, 2, 3, 5-tetrahydro)- pyrano[2, 3-d] pyrimidin-2, 4-diones (or 2-thioxo-4-ones) (3a-f) has been synthesized in one-step by the cyclocondensation of barbituric acid or thiobarbituric acid (1) with arylideneacetophenones (2a-c), in glacial acetic acid in the presence of phosphorous pentoxide. The structures of the compounds 3a-f have been determined by their UV, IR, 1H NMR, 13C NMR, mass spectral data and elemental analyses.
