Abstract

In the title compound, C31H22N4O4, the pyrrolidine ring adopts a twist conformation on the N—CH2 bond. The indolin-2-one and the 1H-indole rings are nearly planar (r.m.s. deviations = 0.06 and 0.011 Å, respectively) and are inclined to one another by 34.19 (9)°. The chromene ring system is also nearly planar (r.m.s. deviation = 0.029 Å). It is almost normal to the 1H-indole ring system, with a dihedral angle of 88.71 (8)°, and is inclined to the indolin-2-one ring system by 72.76 (8)°. In the crystal, molecules are linked via N—H⋯O hydrogen bonds, forming slabs parallel to (10-1). The slabs are linked by C—H⋯O hydrogen bonds, forming a three-dimensional structure.
