    Polycyclic compounds (I) can be prepared in accordance with the following reaction formula: ##STR1## wherein R.sub.1 -R.sub.8 each represents a hydrogen atom, a hydroxyl group, an alkoxyl group or a substituted or unsubstituted benzyloxy group or neighboring two groups of R.sub.1 -R.sub.8 are coupled together to form an alkylenedioxy group; and A is an alkylene group which may be substituted by one or more alkoxycarbonyl groups, an alkenylene group which may be substituted by one or more alkoxycarbonyl groups, or a group represented by any one of the following formulas: ##STR2##
    (I)类多环化合物可以按照以下反应式制备:##STR1## 其中,R.sub.1-R.sub.8分别代表氢原子、羟基、烷氧基或取代或未取代苄氧基,或相邻的两个R.sub.1-R.sub.8基团耦合形成烷二氧基基团;A是一个烷基,可以被一个或多个烷氧羰基基团取代,也可以是一个烯基,可以被一个或多个烷氧羰基基团取代,或者是由下列任一公式表示的基团之一:##STR2##
  • Synthesis of Optically Pure Gomisi Lignans: The Total Synthesis of (+)-Schizandrin, (+)-Gomisin A, and (+)-Isoschizandrin in Naturally Occurring Forms

    The total syntheses of (+)-schizandrin (1), (+)-gomisin A (2), and (+)-isoschizandrin (3) having natural configurations were accomplished. Optically pure butyrolactones ((-)-9, (-)-31) were transformed to alpha-benzylidenebutyrolactones ((+)-10, (+)-32, (+)-35). By a highly efficient iron(III) perchlorate-mediated oxidative coupling reaction of 10, 32, and 35, the key intermediates with biphenyl skeletons ((-)-11, (-)-33) were constructed with high stereoselectivity. Several methods for the stereoselective introduction of the C6-hydroxyl group were examined. For the synthesis of schizandrin and gomisin A, the Mukaiyama hydration reaction of(-)-11 and (-)-33 provided the desired products with satisfactory selectivity. For the synthesis of isoschizandrin, the stereoselective epoxidation of allylic alcohol (+)-48 was successfully utilized taking advantage of its conformational features.

    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。
