Abstract: In the title compound, C14H13ClO5, the five-membered ring is in an envelope conformation with the methylene C-atom being the flap. The conformation about the C=C double bond [1.341 (2) angstrom] is E. The chloropropan-2-one residue is approximately orthogonal to the remaining molecule [dihedral angle = 88.03 (6)degrees]. In the crystal, the molecules associate via C-H center dot center dot center dot O interactions, involving both carbonyl-O atoms, giving rise to an undulating two-dimensional array in the ac plane.
