Diethoxalylacetone reacts with an equimolar amount of a Schiff base, forming 1-substituted 5-aryl-3-hydroxy-4-ethoxalylacetyl-2,5-dihydropyrrol-2-ones and di(1,5-diaryl-2,5-dihydropyrrol-2-on-4-yl) ketones.The reaction of diethoxalylacetone with Schiff bases in a molar ratio of 1:2 leads to ethyl 2-arylamino-4-(1,5-diaryl-3-hydroxy-2,5-dihydropyrrol-2-on-4-yl)-4-oxo-2-butenoates.
