The cationic Au^I‐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 Au^I complex. Two nitrogen atoms in the tether of substrates were critical in this selective transformation.
