Golden Cascade: With a tethered, electron‐rich arene as the internal nucleophile, a gold‐catalyzed amide cyclization to an alkyne initiates a cascadeprocess that ends with a Ferrier rearrangement. Electron‐rich arene‐bearing hexahydroquinolizin‐2‐ones are formed in good yields and can be converted into indole alkaloids in only a few steps.
