The total synthesis of 5-epi-Torrubiellutin C is described in a fully stereocontrolled manner and linear sequence involving high yielding steps. The synthetic strategy involves the dicyclohexylboron chloride mediated Paterson's aldol protocol, Horner–Emmons olefination, TiCl4 mediated syn-aldol reaction and ring closing metathesis (RCM) as the key steps. Furthermore, the resultant epimer was evaluated
以完全立体控制的方式描述了5- Epi -Torrubiellutin C的总合成,并涉及涉及高产步骤的线性序列。合成策略涉及关键步骤,其中包括二环己基氯化硼介导的帕特森氏醇醛规程,霍纳-埃蒙斯烯化,TiCl 4介导的顺-醇醛反应和闭环复分解(RCM)。此外,评估了所得的差向异构体对DU145(前列腺),MCF-7(乳腺癌)和A549(肺癌)癌细胞系的细胞毒性,结果表明,5- Epi- Torrubiellutin C与天然的产品一样好。生物测定。
