The cationic AuI‐catalyzed intramolecular reaction of N‐propargyl‐2‐anilinoanilines gave a diazocine skeleton via 8‐exo‐dig‐selective cycloisomerization. Both terminal and internal alkynes could be used according to the choice of ligand of the AuI complex. Two nitrogen atoms in the tether of substrates were critical in this selective transformation.
