Cycloheptaceanthrylene-5,8-dione 16 and 1,2-dihydrocycloheptaceanthrylene-5,8-dione 15 have both been synthesized in four steps from aceanthrene 9 in 8 and 7 percent overall yield, respectively.On the basis of their reduction potentials, the compound 16 was shown to be an <18>annulenedione with a higher reduction potential than the isomeric cyclopentapleiadene-5,10-dione 2.An unsuccessful attempt to synthesize cycloheptaceanthrylene 21 as well as the efficient synthesis of aceanthrene 9 from anthracene is also described.
