A synthesis and characterization of conveniently functionalized taxoid C-ring building blocks to be used in an A+C approach is presented. Subsequently, a four-step entry to the tricyclic taxoid ABC skeleton, which allows for a high degree of convergency and is highlighted by a stannylene-mediated coupling to link the left- and right-half moieties, followed by an intramolecular aldol reaction to effect
提出了用于A + C方法的功能方便的功能化紫杉醇C环构件的合成和表征。随后,四步进入三环类紫杉醇ABC骨架,实现高度收敛性,并通过亚苯乙烯介导的偶联作用将左半部分和右半部分连接起来,然后通过分子内羟醛反应来实现描述了B形环的闭合。
