The generation of 1 in the presence of cyclic and acyclic dienes affords the Diels−Alder adducts with a complete chemo- (only reaction with the sulfinyl-substituted double bond takes place), regio- (controlled by the cyano group), and endo selectivity (with respect to the quinone moiety), whereas the π-facial selectivity is dependent on the structure of the diene.
