【 摘 要 】
In the title spiro compound, C34H30N2O3, the central pyrrolidine ring is fused with the tetrahydroisoquinoline ring, both having distorted envelope conformations, with the flap atoms being C and N, respectively. The methoxyphenyl group is attached to the pyrrolidine ring, and is disordered over two positions, with refined occupancies of 0.638 (6):0.362 (6) Å. The central pyrrolidine ring is inclined relative to the tetrahydroisoquinoline group, such that the dihedral between the non-flap atoms of each ring system is 11.29 (7)°. The spiro-linkage creates a dihedral angle of 83.26 (5)° between the indolinone ring and the non-flap atoms of the pyrrolidine ring. In the crystal, molecules are linked via C—H...O hydrogen bonds. For the major disorder component, these form C(11) chains that propagate parallel to the a axis.
