In the presence of a strong Lewis base, such as Et 3 N, trithio-1,8-naphthalic anhydride ( 3) is easily oxidized. Two improved syntheses of trithio-1,8naphthalic anhydride (3) are described. Trithio-1,8-naphthalic anhydride (3) undergoes Diels-Alder reactions with electron-deficient alkenes to give
