with kinetically controlled generated lithium dienolate 6a to form chiral bicyclo[2.2.2]octanes 4 with modest d.e.. It was found, that the diastereoselection is improved, when the corresponding trimethylsilyl ether 6b reacts with chiral acrylates under Lewis acid catalysis. The absolute stereochemistry of these bicyclo[2.2.2]octanes was determined by X-ray analysis.
