Syntheses of the methylene-bridged derivatives of benzo[a]pyrene and benzo[e]pyrene (1 and 2) are described. The latter was obtained by a route involving in the key step tandem cyclization of a diacid derivative of pyrene. Although analogous preparation of 1 failed, it was obtained successfully by a synthetic route based on cyclopenta[def]phenanthrene.
