Twisted molecules: A modular approach for the synthesis of tetrasubstituted helical alkenes by a palladium‐catalyzed norbornene‐mediated domino reaction is presented. This intermolecular domino process allows the formation of three CC bonds in one operation through a CH activation/carbopalladation/CH activation sequence.
