Abstract: In the title compound C38H32N4O3, one pyrrolidine ring adopts an envelope conformation with the N atom as the flap while other pyrrolidine ring adopts an twisted conformation. The pyrrolizine ring forms dihedral angles of 79.24 (5) and 77.57 (5)° with the chromene and indole rings, respectively. The carbonyl O atoms deviate from the least-square planes through the chromene and indole rings by 0.0113 (12) and 0.0247 (12) Å, respectively. In the crystal, non-classical C-H...O inter­actions link the mol­ecules, generating an C(9) chain along the b-axis direction.
