Published: October 2016

In the presence of a quinone, Brønsted acid-catalyzed intramolecular C-N bond formation of o-vinylanilines by electrophilic cyclization was developed, giving the corresponding N-arylindoles in good to high yields. The reaction worked well for o-vinylanilines with terminal and internal C=C double bonds.
