Abstract
Methyl 1-aryl-3-aroyl-4,5-dioxo-4,5-dihydro-1H-pyrrole-2-carboxylates react with N-substituted 3-amino-5,5-dimethyl-2-cyclohexenones to give 4′-hydroxy-1′-aryl-3′-aroyl-6,6-dimethyl-1′, 2,3,4,5,5′,6,7-octahydro-1H,2′H-indole-3-spiro-2′-pyrrole-2,4,5′-triones. The structure of the products was proved by the X-ray diffraction data for the 1-cyclohexyl derivative.
