The photochemical synthesis of the title lactone was achieved by irradiation in the presence of Pb(IV) acetate alone or Pb(IV) acetate + calcium carbonate + iodine or mercuric oxide + iodine. Chiroptical measurements (CD) of this and other related lactones provided convincing evidence in support of the lactone ring structure.
