text] The first syntheses of the adducts formed in the reactions of o-quinone metabolites of carcinogenic polycyclic aromatic hydrocarbons (BPQ and BAQ) at 2'-deoxyadenosine and 2'-deoxyguanosine sites in DNA are reported. These syntheses entail Pd-catalyzed coupling of protected amine derivatives of catechols with suitably protected halopurine analogues of 2'-deoxyribonucleosides.
[结构:见正文]报告了在致癌多环芳烃(BPQ和BAQ)的邻醌代谢产物在DNA中2'-脱氧腺苷和2'-脱氧鸟苷位点反应中形成的加合物的首次合成。这些合成需要邻苯二酚的受保护胺衍生物与2'-脱氧核糖核苷的适当保护的卤代嘌呤类似物的Pd催化偶联。
