In these palladium-catalyzed reactions, the α,β-unsaturated ketone framework was an essential factor in facilitating the reaction, since β,γ-unsaturated and saturated ketone derivatives were unreactive toward the acylzirconocene chloride under otherwise identical conditions.

Starting from epoxy alcohol 7 (49% ee), which is obtained by the first kinetic resolution of 6 with (+)-tartrate, gave (R)-2 (43% ee) on applying the same synthetic sequence. Therefore, we believe that no epimerization takes place at the quaternary alcohol carbon atom of 9 throughout the reactions.
