Abstract: In the title compound, C39H38N4O8, the quinoxaline and indene subunits are essentially planar, with maximum deviations of 0.071 (2) and 0.009 (2) Å, respectively. The indeno­quinoxaline system forms a dihedral angle of 72.81 (3)° with the chromenopyrrolizine system. The two dioxolane rings, as well as the pyran ring of the chromeno group and the terminal pyrrolizine, each adopt an envelope conformation with O and C as flap atoms. The central pyrrolizine ring adopts a twisted conformation. Intra­molecular C-H...O and C-H...N hydrogen bonds occur. The crystal structure exhibits C-H...O hydrogen bonds, and is further stablized by C-H...[pi] inter­actions, forming a two-dimensional network along the bc plane.
