efficient AuIII‐catalyzed method to generate the highly reactive cyclic o‐quinodimethane (o‐QDM) species from easily available enynals or enynones is presented (see scheme). This method produced a variety of structurally unique fan‐like products with the advantages of mild reaction conditions, excellent diastereoselectivities, and high functional‐group tolerance.
