چکیده
In the title compound, C(33)H(30)N(2)O(3), the pyrrolidine ring adopts an envelope conformation in which the H atom attached the an ortho-C atom deviates from the plane, whereas the cyclo-hexa-none ring in the tetra-hydro-naphthalene 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 intra-molecular C-H⋯O close contacts are observed. In the crystal, mol-ecules associate via O-H⋯O hydrogen bonds, forming R(2) (2)(14) dimers. In addition, there are weak C-H⋯π inter-actions.
