A highly stereoselective, concise (14 steps longest linear sequence and 20 steps overall), and efficient (15 % overall yield) synthesis of militarinone D has been accomplished. The key reactions utilized in the sequence are enzymatic desymmetrization, cis/trans isomerization, Horner–Wadsworth–Emmons olefination, and addition of an organolithium species to a highly conjugated chiral aldehyde. The simplicity
高度立体选择性、简洁(14 步最长的线性序列和 20 步总步)和高效(15% 总产率)的米利他酮 D 合成已经完成。该序列中使用的关键反应是酶促去对称化、顺式/反式异构化、Horner-Wadsworth-Emmons 烯化以及将有机锂物质添加到高度共轭的手性醛中。该策略的简单性使其可用于该目标的大规模生产。此外,用于设计路线的策略应适用于具有各种取代吡啶酮核心结构的类似物的制备。
