In the Ames test, 9‐hydroxybenzo[a]pyrene is mutagenic. The labile 4,5‐oxide 1 is presumed to be the reactive species. It has been synthesized from 9‐benzo[a]pyrenyl acetate and trapped with ethanethiol. The nucleophilic attack of the thiolate takes place regioselectively at C‐5 of 1. In contrast, benzo[a]pyrene 4,5‐oxide, which lacks a hydroxyl group, is attacked at both C‐4 and C‐5.
