Abstract :
The molecule of the title compound, C15H15Br2NO3, comprises a fused tricyclic system consisting of two five-membered rings (cyclopentane and tetrahydrofuran) and one six-membered ring (tetrahydropyridinone). Both five-membered rings of the tricyclic system have envelope conformations, and the conformation of the six-membered cycle is intermediate between chair and half-chair. In the crystal, the molecules are linked by C—H⋯O hydrogen bonds and C—H⋯π, C—Br⋯π and C⋯O interactions into double layers. The layers are connected into a three-dimensional network by van der Waals interactions.
