A full account of the oxidative dearomatization of para‐ and ortho‐phenolic sulfonamides is provided together with an overview of the chemistry of the products and their elaboration to buildingblocks for spirocyclic alkaloids. A concise total synthesis of putative lepadiformine complements the discussion.
