A synthesis of anti-4, 5, 14, 15-tetramethyl [22](2, 7) naphthalenophane-l, ll-diene (4) has been achieved in ten steps from 1, 8-naphthalic anhydride in an overall yield of 4%. The key step in the synthesis employed a double-barreled sulfur analogue of the Sommelet-Hauser rearrangement. Unexpectedly, formation of the dianion and radical anion of 4 occurred without intramolecular cyclization. The radical anions and the radical cations both of 4 and ...
