ABC analogues of the antitumour antibiotic streptonigrin, that contain the key metal chelation site and redox-active quinone unit that are essential for biological activity, were prepared via palladium catalysed cross-coupling of 2-iodo-8-nitroquinoline or 2-iodo-6-methoxy-5-nitroquinoline with 2-trimethylstannio-6-methylpyridine. Mild oxidation of the pyridyl methyl group introduced the acid functional
通过钯催化的2-iodo-8-nitroquinoline或2-iodo-6的交叉偶联制备了抗肿瘤抗生素链霉菌素的ABC类似物,其中包含对生物活性至关重要的关键金属螯合位点和氧化还原活性醌单元。 -甲氧基-5-硝基喹啉与2-三甲基锡-6-甲基吡啶。吡啶甲基甲基的轻度氧化在环C上引入了酸官能团,弗雷米氏盐的氧化得到了醌单元,该醌单元经过精制后形成了链霉菌素中的5-氨基-6-甲氧基取代基。
