(Image presented) The acid-catalyzed cyclodehydration of (E)-3-[(2-tosylamino)phenyl]-1-(het)aiylprop-2-en-1-ones to 2-substituted quinolones was investigated. The reaction proceeds via the key step of (E,Z)-isomerization with subsequent intramolecular cyclization affording the target compounds in high yields. © 2016 Springer Science+Business Media New York.
