Optically pure samples of (+)- and (-)-benzopyrene 7,8-oxide have been synthesized from the separated diastereisomers of trans-8-bromo-7-menthyloxyacetoxy-7,8,9,10-tetrahydrobenzopyrene.The latter separation was effected by short-column chromatography-recrystallisation or high pressure chromatography.The absolute stereochemistry of (+)-trans-8-bromo-7-menthyloxyacetoxy-7,8,9,10-tetrahydrobenzopyrene has been assigned as (7S,8S) by an X-ray crystal structure analysis; this structure has in turn been unequivocally correlated with the stereochemistry of (7S,8R)-(-)-benzopyrene 7,8-oxide and a range of mammalian metabolites.
