• various scenarios that can be expected with an α,β,γ,δ-unsaturated Michael acceptor. Amongst the variety of transition-metal-based catalytic systems that have been evaluated in ACA reactions on extended Michael acceptors [1][3], copper-based systems have been the subject of tremendous interest, which

• provided dramatic breakthroughs during the last two decades. This review aims to describe the early examples and recent advances in copper-catalyzed asymmetric conjugate additions of organometallic reagents to extended Michael acceptors. First, seminal reports dealing with the reactivity of extended
