  • Enantioselective Lignan Synthesis by Cell-free Extracts of<i>Forsythia koreana</i>
    作者:Toshiaki Umezawa、Hiroyuki Kuroda、Toshinari Isohata、Takayoshi Higuchi、Mikio Shimada
    DOI:10.1271/bbb.58.230
    日期:1994.1
    The Forsythia koreana plant produces such lignans as ( − )-secoisolariciresinol, and ( + )-pinoresinol. Cell-free extracts from the plant catalyzed the enantioselective formation of ( − )-[2H10]secoisolariciresinol from [9, 9-2H2, OC2H3]coniferyl alcohol in the presence of NADPH and H2 O2. On the other hand, [2H10]lariciresinosl isolated from the enzymatic reaction products was found to be predominantly composed of the unnatural ( − )-enantiomer [88% enantiomer excess (e.e.)]. The stereoselectivity for the formation of these lignans can be explained, at least in part, by the finding that the enzyme system also catalyzed the stereoselective reduction of ( + )-lariciresinol, but not its ( − )-enantiomer, to ( − )-secoisolariciresinol.
    韩国连翘植物产生的木酚类物质包括(−)-半紫葳醇和(+)-松脂醇。来自这种植物的无细胞提取物NADPH和H2O2存在下催化了(−)-[2H10]半紫葳醇从[9,9-2H2,OC2H3]香豆醇的对映选择性形成。另一方面,从酶促反应产物中分离出来的[2H10]拉里醇主要由不自然的(−)-对映体构成,具有88%的对映体超量(e.e.)。这些木酚类物质形成的立体选择性部分可以通过发现该酶系统也催化(+)-拉里醇的立体选择性还原,但不催化其(−)-对映体,形成(−)-半紫葳醇来解释。
  • Intramolecular Regioselective Insertion into Unactivated Prochiral Carbon−Hydrogen Bonds with Diazoacetates of Primary Alcohols Catalyzed by Chiral Dirhodium(II) Carboxamidates. Highly Enantioselective Total Synthesis of Natural Lignan Lactones
    作者:Jeffrey W. Bode、Michael P. Doyle、Marina N. Protopopova、Qi-Lin Zhou

    日期:1996.1.1
    Intramolecular insertion into unactivated prochiral C-H bonds of 3-aryl-1-propyl diazoacetates catalyzed by dirhodium(II) tetrakis[methyl 1-(3-phenyl propanoyl)imidazolidin-2-one-4(R or S)-carboxylate], Rh-2(4R-MPPIM)(4) or Rh-2(4S-MPPIM)(4), occurs in 91-96% ee and with virtually complete regiocontrol for the formation of beta-benzyl-gamma-butyrolactones. This methodology has been applied to the total synthesis of dibenzylbutyrolactone lignans (-)- and (+)-enterolactone, (-)- and (+)-hinokinin, and (+)-arctigenin from substituted cinnamic acids in 19-27% overall yields. Aryltetralin lignan (+)-isodeoxypodophyllotoxin was prepared from the reactant 3,4-(methylenedioxy)cinnamic acid in 36% yield overall, and the lactone precursor to (+)-isolauricerisinol was formed in 96.5% ee and 23% yield overall. Applications of the chiral Rh-2(MPPIM)4 catalysts to fully aliphatic systems resulting in the formation of beta-substituted-gamma-butyrolactones with high regiocontrol and with 93-96% ee have demonstrated the generality of this methodology. A model that provides accurate predictions of beta-substituted-gamma-butyrolactone absolute configurations in these asymmetric metal carbene transformations is described.
