A two-step sequence consisting of a Sonogashiracoupling of polyfluorinated 2-iodoanilines with terminal alkynes, followed by a KOH promoted cyclization of the 2-alkynylanilines thus formed, has been developed as a one-potsynthesis of 2-R-indoles (R=n-Bu, Ph, CH2OTHP→CH2OH, C(CH3)2OH→H) containing a polyfluorinated benzene moiety.
