A synthetic use of the intramolecular alkyl migration process in indolylborates for intramolecular cyclization: a novel construction of carbazole derivatives

The intramolecular alkyl migration reaction in indolylborates was developed for the one-pot construction of carbazoles via intramolecular cyclization in which π-allylpalladium complexes were successfully adopted as an acceptor for the indole nucleophile.
