title: Direct intramolecular conjugate addition of simple alkenes to α,β-unsaturated carbonyls catalyzed by Cu(OTf)2.
abstract: An unprecedented intramolecular conjugate addition of simple alkenes to α,β-unsaturated carbonyl compounds has been developed. A simple Lewis acid such as Cu(OTf)2 was found to effectively catalyze the reaction, and six- and five-membered cyclic products were obtained in moderate to high yields.
