A world of possibilities: Gold‐catalyzed reactions of 2‐ethynylbenzyl ethers with organicoxides and α‐diazoesters gave 1,3‐dihydroisobenzofuran and naphthalene derivatives, respectively (see scheme; EWG=electron‐withdrawing group). Mechanisms for the formation of the formal cycloadducts were elucidated by isotope labeling.
