title: (1RS,4SR)-3-Dichloro-methyl-ene-1,4-dimethyl-2-oxabicyclo-[2.2.2]oct-5-ene.
abstract: X-ray crystallography was used to confirm the structure of the enantio-enriched title compound, C(10)H(12)Cl(2)O, a bicylic enol ether. A bridged boat-like structure is adopted and the dichloro-methyl-ene C atom is positioned significantly removed from the core bicyclic unit. In the crystal structure, mol-ecules pack to form sheets approximately perpendicular to the a and c axes.
