(1RS,4SR)-3-Dichloromethylene-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, C10H12Cl2O, a bicylic enol ether. A bridged boat-like structure is adopted and the dichloromethylene C atom is positioned significantly removed from the core bicyclic unit. In the crystal structure, molecules pack to form sheets approximately perpendicular to the a and c axes.
