A simple and efficient stereoselective total synthesis of (+)‐umuravumbolide (1b) and (−)‐deacetylumuravumbolide (1a) starting from commercially available pentanal is described. The synthesis involves Sharpless asymmetric epoxidation, Jacobsen's hydrolytic kinetic resolution (HKR), and the Yamaguchi oxirane opening as key steps (Scheme 2).
描述了一种简单有效的立体选择全合成(+)-umuravumbolide(1b)和(-)-deacetylumuravumbolide(1a)从市售的戊醛开始的合成方法。合成过程包括Sharpless不对称环氧化,Jacobsen水解动力学拆分(HKR)和山口环氧乙烷开口作为关键步骤(方案2)。
