title: Catalytic intermolecular hetero-dehydro-Diels-Alder cycloadditions: regio- and diasteroselective synthesis of 5,6-dihydropyridin-2-ones.
abstract: A novel catalyzed intermolecular heterodehydro-Diels-Alder reaction between push-pull 1,3-dien-5-ynes and aldimines or silylaldimines is reported. The sequence is promoted both by gold(I) or silver(I) catalysts and leads to the diastereo- and regioselective formation of 5,6-dihydropyridin-2-ones.
