  N-Alkyl-N-aryl-1H-benzotriazole-1-methanamines 3, easily accessible from the condensation of anilines with formaldehyde and benzotriazole, undergo acid-catalyzed reactions with ethyl vinyl ether to give 1-allkyl-4-(benzotriazol-1-yl)-1,2,3,4-tetrahydroquinolines 10 and their benzotriazol-2-yl isomers 11. The reaction mechanism involves formation of 1-alkyl-4-ethoxy-1,2,3,4-tetrahydroquinolines 8 as isolable intermediates, followed by substitution of the ethoxy group in 8 with benzotriazole to produce 10 and 11, Treatment with Grignard reagents in toluene converts compounds 10 and 11 in good yield to 4-alkyl- or 4-aryltetrahydroquinolines 12. 2,3-Dihydrofuran and 3,4-dihydro-2H-pyran undergo similar reaction sequences giving tetrahydroquinolines additionally substituted by 3-(beta-hydroxyethyl) and 3-(gamma-hydroxypropyl) groups, respectively. The stereochemistry of 1,3,4-trisubstituted 1,2,3,4-tetrahydroquinolines is assigned on the basis of NOE methodology. An unusual reduction of the benzotriazolyl moiety to a phenylamino group is observed in the case of product 43 obtained from the reaction of 10-(benzotriazol-1-ylmethyl)-4H-phenothiazine with ethyl vinyl ether.
