The first approaches to the 10′-anthronyl-2-anthraquinone skeleton have been devised, allowing two syntheses of the marine natural product albopunctatone. Both routes involve regioselective addition of a nucleophilic masked anthraquinone to a protected chrysazin derivative; the best affords albopunctatone in five steps and 35% overall yield. Albopunctatone exhibits potent inhibitory activity against
已经设计出了10'-蒽基-2-蒽醌骨架的第一种方法,可以对海洋天然产物albopunctatone进行两种合成。两种途径都涉及将亲核掩蔽的蒽醌区域选择性地加成到受保护的Chrysazin衍生物上。最好的方法是分五个步骤提供沙丁苯甲酮,总产率为35%。Albopunctatone对恶性疟原虫表现出有效的抑制活性,对一系列其他微生物病原体和哺乳动物细胞的毒性可忽略不计。
