Cascade migration-aryloxylation of 2-alkyl/alkenyl quinoline N -oxides with phenols: practical synthesis of 2,3-disubstituted quinolines

This strategy bypasses conventional methods by using readily available 2-substituted quinoline N -oxides and phenols to construct 2,3-disubstituted quinolines via [1,2]-alkyl/alkenyl migration under benign conditions.
