Abstract
Here, we report the first synthesis of 2,3-disubstituted quinolines from anilines and aromatic or aliphatic epoxides. This reaction utilizes Sc(OTf)3 as a Lewis acid and TEMPO as an oxygen scavenger. A wide variety of highly substituted quinolines were obtained with moderate to excellent yields (up to 96%).
