| Abstract: | We report a two-step synthesis of 3-ethanoyl 4H-1-benzopyran-4-one in good yield through reaction of anhydrides a 3-(dimethylamino)-1-(substituted-2-hydroxyphenyl)-propen-1-one intermediate which is readily a valuable from o-hydroxyl acetophenone. The structures of all these prepared compounds were characterized by elemental analysis,'H-NMR spectra and MS. |
