Abstract: | Synthesis of CF3-Substituted Quinolines from β-Chloro-β-trifluoromethyl-vinylaldehydes. I 3-(Trifluoromethyl)-acroleines 2 have been synthesized through VILSMEIER's reaction from α-Trifluoro-methylketones 1 . The reaction of 2 with anilines and naphthylamines gives in good yields 2-trifluoromethylquinolines 4 and benzoquinolines 5 . |
