[reaction: see text] An efficient method for the synthesis of oligonucleotides containing a site-specific DNA adduct formed by the carcinogens 1,6- and 1, 8-dinitropyrene has been developed. Palladium-catalyzed amination provided a straightforward route for the synthesis of aminonitropyrenes which, following separation, were reduced to the nitrosonitropyrenes. The N-hydroxyaminonitropyrene, generated
[反应:见正文]已经开发了一种有效的合成寡核苷酸的有效方法,该寡核苷酸包含由致癌物1,6-和1,8-二硝基py形成的位点特异性DNA加合物。钯催化的胺化为氨基硝基nitro的合成提供了一条直接途径,该氨基硝基nitro在分离后被还原为亚硝基nitro。从每个亚硝基苯并吡咯原位生成的N-羟基氨基硝基py成功用于在寡核苷酸的确定位点引入二硝基py衍生的DNA加合物。
