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.

Improved Formal Preparation of Enantiomerically Pure anti-Benzopyrene Diol Epoxide.

We report an improved, economical formal route to enantiomerically pure anti-benzopyrene diol epoxide (BPDE).A trimethylaluminum catalyzed regio- and stereoselective opening of racemic 7,8-epoxy-7,8,9,10-tetrahydrobenzopyrene with Mosher's acid delivers benzylic esters exclusively.This step is a significant improvement over the lack of regioselectivity of standard procedures.We also show that modification of the subsequent chemical steps further shortens the preparation of enantiomerically pure anti-BPDE.
