General description
7,8,9,10-Tetrahydrobenzo[a]pyren-7-ol (7-hydroxy-7,8,9,10-tetrahydrobenzo[a]pyrene), a polycyclic aromatic hydrocarbon (PAH), is a substituted benzopyrene. Its bromination reaction with N-bromosaccharin (NBSac) has been investigated. The sulfotransferase-assisted activation of 7-hydroxy-7,8,9,10-tetrahydrobenzo[a]pyrene to form electrophilic, mutagenic, or tumorigenic sulfuric acid ester metabolite, which binds covalently to DNA and leads to mutation, has been reported.
Application
7,8,9,10-Tetrahydrobenzo[a]pyren-7-ol may be used as a starting material in the synthesis of (±)-trans-7,8-dihydroxy-6-fluoro-7,8-dihydrobenzo[a]pyrene.

Some hydroxymethyl-substituted polycyclic aromatic hydrocarbons have been shown to be converted to electrophilic, mutagenic, or tumorigenic sulfuric acid ester metabolites by cytosolic sulfotransferase activity in rodent liver. Likewise, certain types of aromatic compounds with a secondary alcoholic functional group at

Synthesis of (+/-)-trans-7,8-dihydroxy-6-fluoro-7,8-dihydrobenzo[a]pyrene, the metabolite from 6-fluoro-benzo[a]pyrene, is described. Position 6 of 7,8,9,10-tetrahydrobenzo[a]pyren-7-ol (1) was functionalized by bromination with N-bromosaccharin. Regioselectivity in the bromination is thought to derive from a substrate-reagent hydrogen bond. NMR evidence is offered to support this

The laser excited fluorescence-line-narrowed spectrum of DNA modified with (+/-)-r-7,t-8-dihydroxy-t-9,10-epoxy-7,8,9,10-tetrahydrobenzo[a]pyrene (BPDE), the ultimate carcinogenic metabolite of benzo[a]pyrene (BP), has been obtained in a water-glycerol-ethanol glass at 4.2 K. The spectrum was well resolved and highly characteristic of the chromophore. Comparisons
