In this study, 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 systematically examined, and a possible mechanism was proposed. Derivatization of 2-(naphthalen-2-yl)aniline was carried out to access benzo[alpha]carbazole, benzo[c,h]cinnoline and dibenzo[i]phenanthridine derivatives in a divergent manner.
Comprehensive Summary 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[alpha]carbazole, benzo[c,h]cinnoline and dibenzo[i]phenanthridine derivatives in a divergent way.
