The subject of the present study is acid-catalyzed cyclodehydration of (E)-3-[(2-tosylamino)phenyl]-1-(het)arylprop-2-en-1-ones to 2substituted quinolines. The reaction proceeds via the key step of (E,Z)-isomerization with subsequent intramolecular cyclization to afford the target compounds in high yields.
