13 and convert it into the corresponding TBTQ-based para-benzoquinone 4. The Diels-Alder reaction of 4 with anthracene afforded anti-and syn-cycloadducts 22 and 23, respectively, in the ratio of 1: 3, which were transformed into dibenzo(triptyceno) triquinacene 5, a new parent polycyclic aromatic hydrocarbon, and derivatives 25-28. The structure of TBTQ-quinone 4 was also extended to give related 1,4-anthraquinone
