3′,7′,7′-Trimethyl-1′-phenyl-5′,6′,7′,8′-tetrahydrospiro[indoline-3,4′-(1H,4H-pyrazolo[3,4-b]chromene)]-2,5′-dione

The title spirooxindole compound, C(26)H(23)N(3)O(3), was prepared by the reaction of isatin, 3-methyl-1-phenyl-2-pyrazolin-5-one and 5,5-dimethylcyclohexane-1,3-dione in an ethanol solution. The fused cyclohexene ring adopts an envelope conformation. The dihedral angle between the aromatic and...
