Double C—H Functionalization in Sequential Order: Direct Synthesis of Polycyclic Compounds by a Palladium‐Catalyzed C—H Alkenylation—Arylation Cascade.

Palladium-catalyzed cyclization of m-bromoanilines bearing N-tethered bromocinnamyl groups proceeds via a C—H alkenylation—arylation cascade to afford tetracyclic pyrroline derivatives, e.g. (II), (IV)/(V) or (XI), in moderate to good yields.
