1-Substituted 5-aryl-4-aroyl-3-hydroxy-2,5-dihydro-2-pyrrolones were obtained by the reaction of 5-aroyl-2,3-dihydro-2,3-furandiones with N-(4-dimethylaminobenzylidene)amines.In the case of benzylideneanilines containing p-methoxy and p-nitro groups in the aldehyde fragment the 3-substituted 2,6-diaryl-3,4-dihydro-2H-1,3-oxazin-4-ones are formed.The reaction of 5-aryl-4-halogeno-2,3-dihydro-2,3-furandiones with N-benzylideneanilines leads to the substituted amides of 4-aryl-3-halogeno-2,4-dioxobutyric acids or 1,5-diaryl-4-aroyl-3-hydroxy-2,5-dihydro-2-pyrrolones, depending on the conditions.
