Dibenzo[def,p]chrysene (DBC) (1), is by far the most mutagenic and toxic polycyclic aromatic hydrocarbon identified. Its metabolic activation leads to trans-11,12-dihydroxy-11,12-dihydro-DBC (2), which is further metabolized to the ultimate metabolite, anti-trans-11,12-dihydroxy-13,14-epoxy-11,12,13,14-tetrahydro-DBC (3), that binds to DNA causing mutations and ultimately tumor induction. We report
二苯并[ def,p ]丙烯(DBC)(1)是迄今为止鉴定出的最具致突变性和毒性的多环芳烃。它的代谢活化导致反式-11,12-二羟基-11,12-二氢-DBC(2)进一步代谢为最终的代谢产物,反-反式-11,12-二羟基-13,14-环氧-11 ,12,13,14-tetrahydro-DBC(3),与DNA结合导致突变并最终诱导肿瘤。我们报告了合成DBC(1)及其12-甲氧基衍生物(12-methoxy-DBC)(13)(合成2和3的关键中间体)的简便方法,使用Suzuki交叉耦合方法。
