6a-Nitro-6-(2,2,7,7-tetra­methyl­tetra­hydro-3aH-bis­[1,3]dioxolo[4,5-b:4′,5′-d]pyran-5-yl)-6a,6b,7,8,9,11a-hexa­hydro-6H-spiro­[chromeno[3,4-a]pyrrolizine-11,11′-indeno­[1,2-b]quinoxaline]

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...π inter­actions, forming a two-dimensional network along the bc plane.
