tetrahydroquinolines based upon reaction of aromatic amines and formaldehyde with electronrichalkenes such as styrene, α-methylstyrene, 1-phenylcyclohexene and 3,4-dihydro-2H-pyran. The isolation of alcohols as additional products from reactions conducted in acetonitrile containing trifluoroacetic acid, and the demonstration that these alcohols reacted further under similar reaction conditions to give efficiently

The one pot synthesis of Tetrahydroquinolines can be achieved by reaction of aromatic amines and formaldehyde with a variety of electronrichalkenes including styrenes and enol ethers. The cyclisation is multi-step as evidenced by the isolation of intermediates, which can be cyclised to give the @Tetrahydroquinolines, and by the observation of side-products such as oxazines, and in the case of o-phenylenediamine
