Sc(OTf)(3)-Mediated [4 + 2] Annulations of N-Carbonyl Aryldiazenes with Cyclopentadiene to Construct Cinnoline Derivatives: Azo-Povarov Reaction
[Image: see text] We disclose the first accomplishment of the azo-Povarov reaction involving Sc(OTf)(3)-catalyzed [4 + 2] annulations of N-carbonyl aryldiazenes with cyclopentadiene in chloroform, in which N-carbonyl aryldiazenes act as 4π-electron donors. Hence, this protocol offers a rapid access...
