[GRAPHICS]The synthesis of a thiophene-containing analogue of halenaquinone was realized. Key steps include an alkynyl ketone-benzocyclobutane Diels-Alder reaction to construct the C,D-ring naphthalene subunit, a Heck cyclization to form the quaternary carbon, and a ring closing metathesis to add the A-ring.
