Description
Summary:In the title compound, C31H30N4O, the central pyrrolidine ring adopts an envelope conformation with the methylene C atom being the flap. The quinoxaline and indane rings are each planar, having r.m.s. deviations of 0.030 and 0.050 Å, respectively. The pyrrolidine ring mean plane forms dihedral angles of 88.25 (1) and 83.76 (1)° with the quinoxaline and indane rings, respectively. Intramolecular C—H...O and C—H...N interactions are observed. In the crystal, C—H...π interactions lead to helical supramolecular chains along the b-axis direction.
