A novel three-component stereoselective synthesis of (E)-4-alkene 1,3-diketones from lithium selenolates, 1-(1-alkynyl)cyclopropylketones, and aldehydes is reported. This reaction afforded the products in moderate to good yields with the formation of a new C–Se single bond, a new C–C double bond, and a new C–O double bond.
