چکیده
The title compound, C16H15NO3, consists of an oxabicycle fused to an N-phenyl-substituted pyrrolidine ring anti to the double bond, affording the exo isomer. In the oxabicycle system, the six-membered ring presents a boat conformation, while the heterocyclic rings show envelope conformations with the O atom projected out of the plane. In the crystal, adjacent mol-ecules are linked via weak C-H⋯O hydrogen bonds, forming chains propagating along the a-axis direction. The chains are linked by C-H⋯π inter-actions, forming two-dimensional networks lying parallel to the ac plane.

In the title compound, C17H11Cl6NO4, the configuration of the cyclo-alkene skeleton is endo,cis. The benzene ring is twisted by 58.94 (8)° from the attached pyrrolidine ring. Two carbonyl groups play a key role in the crystal packing. A short inter-molecular C⋯O distance of 3.017 (3) Å reveals that one carbonyl group is involved in dipole-dipole inter-actions, which link two adjacent enanti-ome...
