Highly substituted 3-iodoquinolines bearing different alkyl and aryl moieties can be synthesized in good yields by a regioselective 6-endo-dig iodocyclization of 2-tosylaminophenylprop-1-yn-3-ols with molecular iodine under mild conditions. The resulting 3-iodoquinolines can be further functionalized by various coupling reactions.
