Two different approaches to synthesize oligonucleotides containing the 2 ′-deoxyguanosine adducts formed by nitropyrenes are described. A direct reaction of an unmodified oligonucleotide with an activated nitropyrene derivative is a convenient biomimetic approach for generating the major adducts in DNA. A total synthetic approach, by contrast, involves several synthetic steps, including Buchwald-Hartwig
描述了两种不同的合成寡核苷酸的方法,这些寡核苷酸包含由硝基吡啶形成的2'-脱氧鸟苷加合物。未经修饰的寡核苷酸与活化的硝基py衍生物的直接反应是一种方便的仿生方法,用于在DNA中生成主要的加合物。相比之下,总的合成方法涉及几个合成步骤,包括Buchwald-Hartwig Pd催化的偶联,但可用于以高收率将主要和次要加合物掺入DNA中。
