Novel diethyl (4‐oxo‐3,4‐dihydro‐2 H ‐chromeno[2,3‐ d ]pyrimidin‐2‐yl)phosphonate as two enantiomers and diethyl (4‐oxo‐1,5‐dihydro‐4 H ‐chromeno[2,3‐ d ]pyrimidin‐5‐yl) phosphonate were obtained in easy procedure via reaction of 2‐imino‐2 H ‐chromene‐3‐carboxamide, dimethylformamide dimethyl‐acetal, and diethyl phosphite in a simple one pot. Possible reaction mechanisms were proposed. The structures of the obtained products were confirmed by elemental analyses and spectral tools.
