The total synthesis and cytotoxic evaluation of C-9 epimers of herbarumin-II and its C-2 epimer are described for the first time. The key transformations of the synthesis include Wittig olefination, MacMillan α-hydroxylation, Pinnick oxidation, Yamaguchi esterification, and intramolecular ring closing metathesis.
首次描述了标本蛋白II的C-9差向异构体及其C-2差向异构体的总合成和细胞毒性评估。合成的关键转变包括Wittig烯烃化,MacMillanα-羟基化,Pinnick氧化,Yamaguchi酯化和分子内闭环复分解。
