Experimental and computational studies on the palladium-catalyzed intramolecular dearomatization, electrophilic addition, intermolecular coupling sequence

An unprecedented Pd-catalyzed highly stereoselective synthetic strategy for the construction of a broad spectrum polycyclic fused indoline skeletons employing N -halobenzoyl o -haloanilines and N -(prop-2-yn-1-yl)anilines as has been described.
