triptonide has been achieved based on metal-mediate reactions. Specially, Noyori’s ruthenium catalyzed enantioselective transfer hydrogenation, indium(III) catalyzed cationic polyene cyclization, palladium catalyzed carbonylation, rhodium catalyzed double bond migration, and palladium catalyzed ortho sp2 C–H bond oxygenation reactions served as convenient entry points for the preparation of the tetracyclic
雷公藤甲素和雷公藤甲素的正式合成已基于金属介导的反应完成。特别是,Noyori的钌催化的对映选择性转移氢化,铟(III)催化的阳离子多烯环化,钯催化的羰基化,铑催化的双键迁移和钯催化的邻位sp 2 C–H键加氧反应是方便制备的入口点。四环结构单元和C14羟基。
