A direct regio-, diastereo-, and enantiocontrolled access to α,β-unsaturated δ-lactones is described, based on the reaction of a silyl dienolate and an aldehyde in the presence of 10% of Carreira's catalyst. The scope and limitations of this reaction, as well as mechanistic insights concerning the reactivity of an allyl copper species, are discussed.
