We report herein a concise total synthesis of streptovertidione, and its transformation to streptovertidine A and formicapyridine A through a bioinspired pyridination. This strategy features: (1) a one-pot Ti(O-Pr)-mediated photoenolization/Diels-Alder (PEDA) reaction/oxidative aromatization sequence for the construction of -dimethyl-anthracenone, a naturally occurring antibiotic pharmacophore; (2) a late-stage pyridination based on the biosynthetic hypothesis. This efficient route supports the preparation of other formicapyridines and derivatives.
我们在此报告了streptovertidione 的简洁全合成，以及通过生物启发的吡啶化将其转化为streptovertidine A 和 formicapyridine A。该策略的特点是：（1）一锅 Ti(O-Pr)介导的光烯醇化/Diels-Alder（PEDA）反应/氧化芳构化序列，用于构建天然存在的抗生素药效团 -二甲基-蒽酮；（2）基于生物合成假设的晚期吡啶化。这种高效的路线支持其他 formicapyridines 和衍生物的制备。
