Synthesis of 1,2-dihydroquinolines

Recent Literature


A facile and efficient iron-catalyzed intramolecular allylic amination of 2-aminophenyl-1-en-3-ols proceeded smoothly to afford 1,2-dihydroquinoline and quinoline derivatives under mild reaction conditions with good yields.

An efficient synthetic route to 1,2-dihydroquinolines relies on AuCl3/AgSbF6-catalyzed intramolecular allylic amination of 2-tosylaminophenylprop-1-en-3-ols in good yields. The method was shown to be applicable to a broad range of 2-tosylaminophenylprop-1-en-3-ols containing electron-withdrawing, electron-donating, and sterically demanding substrate combinations.P.
