stereocontrolled total synthesis of aspidophytine is described. The key indole intermediate was prepared by radical cyclization of 2-alkenylphenylisocyanide, followed by Sonogashira-coupling with a highly functionalized terminal acetylene. The 11-membered cyclic amine, a precursor for the formation of the aspidosperma skeleton, was synthesized using nitrobenzenesulfonamide chemistry. After construction
描述了对映体立体控制的蛇蝎碱的全合成。通过2-烯基苯基异氰酸酯的自由基环化,然后与高度官能化的末端乙炔进行Sonogashira偶联,制备关键的吲哚中间体。使用硝基苯磺酰胺化学方法合成了11元环胺,这是一种用于形成孢子精子骨架的前体。在构建五环骨架之后,形成内酯环以完成总合成。
