Indium(III)‐catalyzed cyclization reactions of aromatic 5‐enynamides were studied. Indium triflate enabled the efficient synthesis of 2‐aminonaphthalenes and 2‐amino‐1H‐indenes from aromatic N‐methyl‐N‐tosyl‐ynamides bearing an ortho‐vinyl and ‐isobutenyl group, respectively. The aromatic N‐3‐arylpropargylynamides bearing an ortho‐gem‐dihalovinyl subunit underwent a tandem cyclization/carbobromination reaction in the presence of indium tribromide to provide the dibrominated 2,3‐dihydro‐1H‐indeno[2,1‐b]pyridine derivatives in good yields.
