Abstract

Acid-catalyzed cyclization of 3, 3', 4, 4'-tetrahydro-l, lr-binapthyl (I, Scheme I) for 12 h using Amberlyst-15 (A-15) 2 in refluxing toluene provided, as the major product, a CzoHza olefin which was thought to be 1, 2, 3, 6b, 7, 8-hexahydrobenzoli] fluoranthene (2a) or 1, 2, 3, 7, 8, 12c-hexahydrobenzolj] fluoranthene (2b).
