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

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
