SYNTHESES OF METHYLENE-BRIDGED BENZOPYRENES, CARCINOGENIC COMPONENTS OF AUTOMOBILE EXHAUST RESIDUE

Syntheses of the methylene-bridged derivatives of benzopyrene and benzopyrene (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 cyclopentaphenanthrene.
