title: Ethyl 8,13-dioxa-21-aza-penta-cyclo-[18.5.1.0(2,7).0(14,19).0(21,25)]hexa-cosa-2(7),3,5,14,16,18-hexa-ene-26-carboxyl-ate.
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⋯π inter-actions.
