ABSTRACT
In the title compound, C(26)H(22)N(2)O(4), the pyrrolidine ring adopts a twisted conformation and the other five-membered rings adopt envelope conformations with the spiro C atoms as the flap atoms. The naphthalene ring system of the dihydro-acenaphthyl-ene group forms dihedral angles of 89.2 (9) and 75.5 (6)° with the pyrrolidine and indole rings, respectively. The pyrrolidine ring makes a dihedral angle of 80.1 (9)° with the indole ring. In the crystal, mol-ecules are linked by weak C-H⋯O hydrogen bonds, forming chains along the b-axis direction.
