摘要：
Three-component condensation of methyl 4-(furan-2-yl)- and 4-(thiophen-2-yl)-2,4-dioxobutanoates with aromatic aldehydes and 1,3-thiazol-2-amine afforded 5-aryl-4-(hetaren-2-ylcarbonyl)-3-hydroxy-1-(1,3-thiazol-2-yl)-2,5-dihydro-1H-pyrrol-2-ones. Reactions of the latter with hydrazine and phenylhydrazine gave pyrrolo[3,4-c]pyrazol-6-ones and 3-phenylhydrazones, while the corresponding oximes were obtained in reactions with hydroxylamine.
