atom‐economical method for synthesizing N‐heterocyclic indolesfrom readily available o‐alkynylphenyl isothiocyanates and propargylamine derivatives is reported. This method involves a copper‐catalyzed cascade bicyclization process consisting of an intramolecular 5‐exo‐dig hydrothiolation reaction and an intramolecular hydroamination reaction and, depending on whether or not molecular oxygen is present
