New bicyclo[2.2.2]oct-5-en-2-ones of the formulae Ia and Ib in the form of pure enantiomers and processes for preparing them are described. The compounds are used for the preparation of pure enantiomers of the formula V by sensitized photoreaction or of compounds of the formula VI by unsensitized photoreaction.
