抜粋

The cationic AuI-catalyzed intramolecular reaction of N-propargyl-2-anilinoanilines gave a diazocine skeleton via 8-exo-dig-selective cycloisomerization by the suppression of 6-endo-dig cycloisomerization. Both terminal and internal alkynes could be used according to the choice of ligand of the AuI complex, and various dibenzo[b,e][1,4]diazocines were obtained. Control experiments suggested that two nitrogen atoms in the tether of substrates were critical in this selective transformation.
