A novel gold‐catalyzed 6‐exo‐dig cycloisomerization of o‐propargylbiaryls has been developed that provides ready access to functionalizedphenanthrenes in largely good to excellent yields. Notable features of this method are readily available starting materials, mild reaction conditions, and broad substrate scope.
