Copper-catalyzed conjugate addition reactions of Grignard reagents to γ-alkoxy-α,β-unsaturated ketones, derived from mandelic acid, have been studied. Diastereoselectivity is strongly dependent on the nature of the γ-alkoxy protection group. Bulky silyl protection gives poor stereoselectivities, whereas the ketone bearing benzyloxymethylene (BOM) protection reacts with excellent yields and stereoselectivities.
