A gold(I)-catalyzed 6-endo-dig cyclization of aromatic 1,5-enynes was developed to synthesize 2-(naphthalen-2-yl)anilines. The functional group tolerance of this cyclization was examined systematically and a possible mechanism was proposed. The derivatization of 2-(naphthalen-2-yl)aniline was carried out to facile access to benzo[α]carbazole, benzo[c,h]cinnoline and dibenzo[i]phenanthridine derivatives in a divergent way.

A gold-catalyzed tandem cyclization of o-phenylenediamines with ynones to synthesize benzo[b]indeno[1,2-e][1,4]diazepine has been developed. The mechanism was explored by control experiments. The method provides a way to access a range of benzo[b]indeno[1,2-e][1,4]diazepine derivatives in diversity-oriented synthesis aiming at discovering structurally diverse scaffolds.
