The biomimetic formal synthesis of the antibiotic platensimycin for the treatment of infection by multidrug-resistant bacteria was accomplished starting from either ent-kaurenoic acid or grandiflorenic acid, each of which is a natural compound available in multigram scale from its natural source. Apart from the natural origin of the selected precursors, the keys of the described approach are the long-distance
用于治疗多重耐药细菌感染的抗生素平板霉素的仿生正式合成是从对映贝壳杉烯酸或大花烯酸开始完成的,这两种酸都是来自其天然来源的多克规模的天然化合物。除了所选前体的天然来源外,所述方法的关键是对映贝壳杉烯酸在 C11处的长距离官能化以及二萜框架 A 环降解的有效方案。
