Calystegine B2, B3, and B4 have been prepared in 5 steps from the benzyl protected methyl 6-iodoglycopyranosides of glucose, galactose and mannose, respectively, by using a zinc-mediated domino reaction followed by ring-closing olefin metathesis as the key steps.
Calystegine B2、B3 和 B4 分别由葡萄糖、半乳糖和甘露糖的苄基保护的甲基 6-碘糖吡喃糖苷分 5 步制备,采用锌介导的多米诺骨牌反应,然后是闭环烯烃复分解作为关键步骤。
