3-(4-Chloro­phen­yl)-4-(4-methoxyphen­yl)-6-(phenyl­selenylmeth­yl)-2,3,3a,3b,4,5,5a,6,1′′,2′′,3′′,4′′-do­deca­hydro­azeto[2′,3′:3,4]pyrrolo[1,2-b]isoxazole-2-spiro-2′′-naphthalene-5,1′′-dione

In the title compound, C(36)H(31)ClN(2)O(4)Se, the four-membered β-lactam ring is fused to a pyrrolidine ring. The central five-membered ring of the fused tricyclic system exhibits an envelope conformation with the N atom as the flap, while the other five-membered ring exhibits a twist conformation. The chloro­phenyl ring is almost perpendicular to the pyrrolidine ring, making a dihedral angle of 73.45 (1)°. The crystal structure is stabilized by weak inter­molecular C—H⋯O inter­actions and the packing is further enhanced by C—H ⋯N inter­actions and π–π inter­actions between benzene rings of tetra­lone groups in mol­ecules related by an inversion center, with a centroid–centroid separation of 3.8923 (2) Å.
