Reaction of 1-Antipyryl-4-aroyl-5-methoxyrabonyl-1H-pyrrol-2,3-diones with N-Substitutedand N-Unsubstituted 3-Amino-5,5-dimethylcyclohexen-2-ones

The article considers nucleophilic transformations of N-antipyryl-substituted-1H-pyrrole-2,3-diones under the action of dimedone imine and N-substituted dimedone imines, acting as 1,3-CH,NH-binucleophilic reagents, with the formation of 1'-antipyryl-3'-aroyl-4'-hydroxy-6,6-dimethyl-6,7-dihydrospiro[indole-3,2'-pyrrole]-2,4,5'(1H,1'H,5H)-triones and 1'-antipyryl-1-aryl-3'-aroyl-4'-hydroxy-6,6-dimethyl-6,7-dihydrospiro[indole-3,2'-pyrrole]-2,4,5'(1H,1'H,5H)-triones.
