A concise synthesis of TMC-205 was accomplished in two steps via a protecting-group-free (PGF) and redox-economical strategy. In this approach, a high yield Pinnick oxidation and a practical Heck-dehydration reaction with high atom economy as well as a high regio- and stereo-selectivity (E-isomer) were used and further applied to the total synthesis of its active analogues. This newly established route
通过无保护基团 (PGF) 和氧化还原经济策略,TMC-205 的简明合成分两步完成。在该方法中,使用高产率 Pinnick 氧化和具有高原子经济性以及高区域和立体选择性(E-异构体)的实用 Heck 脱水反应,并进一步应用于其活性类似物的全合成。这条新建立的路线将有利于未来的构效关系(SAR)和生物学研究。本文展示的合成策略和方法可以扩展到相关的生物活性天然产物。
