Diastereomeric formaldehyde acetals, formed from the reaction of racemic benzo[a]pyrene dihydrodiol and (-)-chloromethylmenthyl ether, are novel intermediates for effecting the convenient resolution of these metabolites by HPLC. This resolution technique seems generally applicable since the dihydrodiols of benzo[c]phenanthrene can also be readily resolved through this methodology. Key differences in the proton NMR spectra of the diastereomeric dihydrodiol menthyloxymethyl ethers have been identified which could be used for absolute stereochemical assignments.
Enantioselective Synthesis of the (+)-anti-7,8-Dihydrodiol-9,10-epoxide of the Potent Carcinogen Benzopyrene

The title compound, the most important genotoxic metabolite of benzopyrene, has been prepared efficiently in a synthesis which capitalized on Jacobsen-type enantioselective epoxidation of 9,10-dihydrodibenzopyrene, cleavage of the epoxide by KOH-Me2SO to give the tetrahydro-trans-7,8-diol, and formation of the dibenzoate from which the contaminating antipode was removed by crystallization.
