Synthesis of Methylpyridine Derivatives. XXXIV. Condensation of Acetoacetamide with Ketones to form Pyridone Derivatives

Condensation of acetoacetamide (1) with acetone in polyphosphoric acid (PPA) gave 4,6-dimethyl-2(1H)-pyridone (2a) in 32percent yield.Similarly, the amide 1 was condensed with 2-butanone, 2-pentanone, 3-pentanone, cyclopentanone, cyclohexanone, cycloheptanone, acetophenone, and propiophenone to give the corresponding pyridone derivatives (2b-i) in 13-76percent yields.Condensation of the amide 1 with acetylacetone and ethyl acetoacetate gave 3-acetyl-4,6-dimethyl-2(1H)-pyridone (5) and ethyl 4,6-dimethyl-2(1H)-pyridone-5-carboxylate (6), respectively.Self-condensation of the amide 1 in PPA gave 3-acetyl-4-hydroxy-6-methyl-2(1H)-pyridone (7).
