Cover Picture: Trienamine Catalysis with 2,4‐Dienones: Development and Application in Asymmetric Diels–Alder Reactions (Angew. Chem. Int. Ed. 18/2012)

An asymmetric Diels-Alder cycloaddition of δ,δ-disubstituted 2,4-dienones by trienamine catalysis with cinchona-based primary amines has been developed. In their Communication on page 4401 ff., Y.-C. Chen and co-workers show that a wide range of electron-deficient dienophiles were tolerated in this reaction to afford multifunctional cyclohexene derivatives with excellent stereoselectivity.
