title: 3-(2,4-Dichloro-phen-yl)-2-oxo-1-oxaspiro-[4.5]dec-3-en-4-yl 2-methyl-prop-2-enoate.
abstract: In the title mol-ecule, C(19)H(18)Cl(2)O(4), the cyclo-hexane ring adopts a chair conformation. The furan ring is essentially planar and forms a dihedral angle of 82.1 (1)° with the benzene ring. In the crystal, weak C-H⋯O interactions are present.
