Abstract

Methyl 1-aryl-3-benzoyl-4,5-dioxo-4,5-dihydro-1H-pyrrole-2-carboxylates reacted with 3-arylamino-5,5-dimethylcyclohex-2-en-1-ones in boiling benzene to give the corresponding 1,1′-diaryl-3′-benzoyl-4′-hydroxy-6,6-dimethyl-1,1′,2,4,5,5′,6,7-octahydrospiro[indole-3,2′-pyrrole]-2,4,5′-triones and 1′-aryl-4-arylamino-3-benzoyl-6′,6′-dimethyl-1′,2′,4′,5′,6′,7′-hexahydro-5H-spiro[furan-2,3′-indole]-2′,4′,5-triones whose structure was proved by X-ray analysis.
