ChemInform Abstract
The 6-phenylselenyl group completely controls the stereochemistry of the conjugate dimethyllithiumcuprate addition to the endo- tricyclodecadienone (I) to give title compound (III) in nearly quantitative yield as single addition product. The endo configuration of the C-5 methyl group is confirmed by X-ray diffraction analysis.
