Abstract
An efficient single-step approach toward the synthesis of 2-alkylquinolines is mediated by a Lewis acid through [3 + 3] annulation reaction between 3-ethoxycyclobutanones and aromatic amines. Various multisubstituted 2-alkylquinoline derivatives were prepared regioselectively at room temperature.
