A high‐yielding silver(I)‐ or copper(II)‐catalyzed dearomatizing spirocyclization strategy allows the conversion of simple aromatic compounds that contain ynone substituents, including indole, anisole, pyrrole, and benzofuran derivatives, into functionalized spirocyclic scaffolds. A high‐yielding asymmetric variant furnishes spirocyclic indolenines in up to 89:11 e.r.
