General Characteristics
The condensation of aldehydes, anilines, and electron-rich alkenes provides access to substituted tetrahydroquinoline skeletons. This is a type of three-component reaction involving hetero Diels-Alder cycloaddition. Tetrahydroquinolines can be oxidized to quinolines if needed.
