The catalytic asymmetric coupling of 1,3-dienes with carbon nucleophiles is an important process for forming Csp3–Csp3 bonds. Here, we describe a synergistic Pd/Cu-catalyzed coupling of 1,3-dienes with 2-acylimidazoles. This reaction produces 2-acylimidazole derivatives that have α,β-adjacent stereocenters in moderate yields with good to excellent stereoselectivity.
