Abstract:	Reactions of isopropyl 2-(1-aryl-4,5-dioxo-2-phenyl-4,5-dihydro-1H-pyrrol-3-yl)-2-oxoacetates with aromatic amines involve a pyrroledione-pyrroledione recyclization to form isopropyl 1-aryl-2-hydroxy-4,5-dioxo-3-phenyl(arylamino)methylene]pyrrolidine-2-carboxylates. The crystal and molecular structure of (Z)-isopropyl 2-hydroxy-4,5-dioxo-1-phenyl-3-phenyl(phenylamino)methylene]pyrrolidine-2-carboxylate was proved by XRD analysis.
