Deskripsi
In the title compound, C33H30N2O3, the pyrrolidine ring adopts an envelope conformation in which the H atom attached the an ortho-C atom deviates from the plane, whereas the cyclohexanone ring in the tetrahydronaphthalene fused-ring system adopts a sofa conformation. The oxindoline ring system is almost perpendicular with respect to the mean plane of the pyrrolidine ring, with a dihedral angle of 89.0 (1)°. Five intramolecular C—H...O close contacts are observed. In the crystal, molecules associate via O—H...O hydrogen bonds, forming R22(14) dimers. In addition, there are weak C—H...π interactions.
