Ring transformation of 1-substituted 3,5-dinitro-2-pyridones with 1,3-disubstituted acetones in the presence of secondary or primary amines gave <I>p</I>-nitroaniline derivatives and <I>N</I>-substituted 2-nitroacetamide. Two types of enamine intermediates, 2-azabicyclo[3.3.1]nonene derivatives and <I>N</I>-substituted 2-(5-amino-2-nitro-2,4-cyclo-hexadienyl)-2-nitroacetamides were isolated and characterized. The course of the base-catalyzed reaction is interpreted.
