Abstract: In the title compound, C26H31NO4, the five-membered rings of the central pyrrolizine system adopt N-envelope conformations. The ethyl acetate group adopts an extended conformation. The dihedral angle between the benzene rings is 36.6 (1)°. In the crystal, C-H...O hydrogen bonds form a zigzag chain running along the b-axis directions. The crystal structure is futher consolidated by C-H...[pi] interactions.
