Palladium-catalyzed intramolecular trapping of the Blaise reaction intermediate for tandem one-pot synthesis of indole derivatives.

Palladium-catalyzed intramolecular N-arylative and N-alkylative/N-arylative trappings of the Blaise reaction intermediates could be a new route to construct the indole moiety in a tandem one-pot manner from nitriles.
