A new method for Anionic Diels-Alder chemistry using electron-deficient cross-conjugated vinylogous alkenones has been developed, resulting in highly stable sodium dienolate ion pairs as electron-rich dienes in THF with a weak sodium base, leading to a single Diels-Alder adduct in racemic form with moderate to high yields (up to 97%, 37 examples).
Anionic Diels-Alder chemistry of electron-deficient cross-conjugated vinylogous alkenones, providing highly stable sodium dienolate ion pairs as electron-rich dienes in the presence of a weak sodium base in THF, has been newly developed, leading to a single Diels-Alder adduct, in racemic form, in moderate to high yields (up to 97%, 37 examples).
