Abstract New and stereoselective syntheses of (1,2,3/4)-, (1,2/3,4)-, (1,4/2,3)-, and (1,2,4/3)-cyclohexanetetrols (1, 2, 3, and 4 respectively) are described. The known syn and anti 1,4-cyclohex-2-enediols 9 and 10 were used as starting materials. Diols 9 and 10 were allow to react with OsO4 to directly form 3 and 1 respectively. Diols 9 and 10 were epoxidized with MCPBA, which yielded 4 and 2 after
摘要 (1,2,3/4)-, (1,2/3,4)-, (1,4/2,3)- 和 (1,2,4/3)- 的新立体选择性合成描述了环己四醇(分别为 1、2、3 和 4)。已知的顺式和反式 1,4-环己-2-烯二醇 9 和 10 用作起始材料。二醇 9 和 10 可以与 OsO4 反应,分别直接形成 3 和 1。二醇 9 和 10 用 MCPBA 环氧化,在酸催化环氧化物开环后产生 4 和 2。
