Abstract
A convenient one-pot assembly of 4-(imidazol-1-yl)indole derivatives from easily accessible o-alkynylanilines and imidazoles has been developed. The sequential dearomatization and Ag(I)-catalyzed cyclization/Cs2CO3-mediated conjugate addition/aromatization cascade reactions exhibit high efficiency and excellent selectivity. The combined use of a silver(I) salt and cesium carbonate is significant for facilitating this domino transformation. The 4-(imidazol-1-yl)indole products could be easily converted to the corresponding derivatives and might be valuable in biological chemistry and medicinal science.
