Abstract: Abstract We have developed a Au-promoted Pd-catalyzed cyclization/cross-coupling of N,N-dimethyl-o-alkynylaniline with aryl iododes to synthesize 2,3-diarylindoles under mild and base-free conditions. A related vinyl-Au species has been isolated through Au-promoted cyclization of N,N-dimethyl-o-alkynylaniline and structurally… read more here.
