Synthesis of Cyclopentapyrene-3,4-oxide, the Suspected Ultimate Carcinogenic Metabolite of Cyclopentapyrene

A synthesis of cyclopentapyrene-3,4-oxide, the suspected ultimate carcinogenic metabolite of the widely distributed environmental carcinogen cyclopentapyrene, is described.

Quantitative Synthesis and Formation of Cyclopentapyrene 3,4-Oxide under Simulated Atmospheric Conditions

Cyclopentapyrene 3,4-oxide (2) has been synthesized in a one-step, quantitative reaction using dimethyldioxirane. The oxide, or its thermal rearrangement products cyclopentapyren-3(4H)-one and cyclopentapyren-4(3H)-one, is formed from cyclopentapyrene (1) under simulated environmental conditions. In one case these products are formed when 1 is adsorbed on model particulates and then exposed to the reaction products of tetramethylethylene and ozone in the gas phase.
