RESUMO
In the title spiro compound, C34H30N2O3, the central pyrrolidine ring is fused with the tetra-hydro-iso-quinoline ring, both having distorted envelope conformations, with the flap atoms being C and N, respectively. The meth-oxy-phenyl group is attached to the pyrrolidine ring, and is disordered over two positions, with refined occupancies of 0.638â (6):0.362â (6)â Å. The central pyrrolidine ring is inclined relative to the tetra-hydro-iso-quinoline group, such that the dihedral between the non-flap atoms of each ring system is 11.29â (7)°. The spiro-linkage creates a dihedral angle of 83.26â (5)° between the indolinone ring and the non-flap atoms of the pyrrolidine ring. In the crystal, mol-ecules are linked via C-Hâ¯O hydrogen bonds. For the major disorder component, these form C(11) chains that propagate parallel to the a axis.
