of 2′-deoxyguanosine-C8 (dG-C8) adducts with several mutagenic and carcinogenic amino- or nitro-arenes were developed using the palladium-mediated cross-coupling reaction of protected 8-amino-dG with bromoarenes in around 80% yields, followed by conventional deprotection procedures. This approach can be applied to preparation of a variety of authentic dG-C8 adducts with amino or nitro-arenes.
利用钯介导的受保护的8-氨基-dG与溴代芳烃的交叉偶联反应,开发了合成具有几种致突变和致癌的氨基或硝基芳烃的2'-脱氧鸟苷-C8(dG-C8)加合物的合成方法。大约80%的收率,然后进行常规的脱保护程序。该方法可用于制备各种带有氨基或硝基芳烃的可靠的dG-C8加合物。
