Nucleophilic and Electrophilic Double Aroylation of Chalcones with Benzils Promoted by the Dimsyl Anion as a Route to All Carbon Tetrasubstituted Olefins
Dimsyl anion promoted the polarity reversal of benzils in a Stetter-like reaction with chalcones to give 2-benzoyl-1, 4-diones (double aroylation products), which, in turn, were converted into the corresponding tetrasubstituted olefins via aerobic oxidative dehydrogenation catalyzed by Cu (OAc) 2.
