The total syntheses of the metabolites of schizandrin were achieved. The tetracyclic lactone intermediates (13a–e) were prepared in optically pure form by the oxidative coupling reaction of the corresponding 3-benzyl-1-benzylidenebutyrolactones. Mukaiyama hydration of 13b afforded hydroxylactone (14), which was converted into SZ-M3 (4). The introduction of C6,7-diol moiety, which is common to the metabolites
实现了五味子素代谢物的总合成。通过相应的3-苄基-1-亚苄基丁内酯的氧化偶合反应,以光学纯净的形式制备了四环内酯中间体(13a-e)。Mukaiyama水合13b提供了羟基内酯(14),将其转化为SZ-M3(4)。通过连续的双键迁移到15a-e,将内酯环还原成烯丙基二醇(32a-e)和连续的双键迁移,引入了代谢物(4-11)常见的C6,7-二醇部分。乙二醇的形成。然后,甲磺酸酯33的还原完成了代谢物的合成。
