  • Hypoiodite-catalysed oxidative homocoupling of arenols and tandem oxidation/cross-coupling of hydroquinones with arenes
    作者:Muhammet Uyanik、Dai Nagata、Kazuaki Ishihara

    日期:——
    We report the hypoiodite-catalyzed oxidative C–C homocoupling of arenols to biarenols or biquinones using aqueous hydrogen peroxide as an oxidant. In addition, by combining hypoiodite catalysis and lipophilic Lewis acid-assisted Brønsted acid catalysis under aqueous conditions, we achieved a tandem oxidation/cross-coupling reaction of hydroquinones with electron-rich arenes. These results highlight
    我们报告了使用过氧化氢水溶液作为氧化剂的次碘酸盐催化氧化 C-C 同偶联的壬醇与双烯醇或双醌。此外,通过在水性条件下结合次碘酸盐催化和亲脂性路易斯酸辅助布朗斯台德酸催化,我们实现了对苯二酚与富电子芳烃的串联氧化/交叉偶联反应。这些结果突出了次碘酸盐/酸共催化在氧化偶联反应中的应用范围。

    naphthyl pinacol boronate and an aryl iodide, bearing (S)-2-aminopropyl group at the ortho-position using the existing central chirality as an atroposelectivity-controlling group, provided the desired biaryl product with high atroposelectivity, without the use of an external chiral source. From the resulting biaryl product, several naphthylisoquinoline alkaloids were prepared via the stereoselective formation
    我们描述了萘基异喹啉生物碱的不对称总合成。使用现有的中心手性作为阻转性选择性控制基团,在萘甲酸萘哪醇硼酸酯与在正位置带有(S)-2-氨基丙基的芳基碘化物之间进行阻转性联芳基偶合反应,可提供所需的具有高阻转性的联芳基产物,而无需使用外部手性来源。由所得的联芳基产物,通过具有适当氧化态和立体化学的异喹啉骨架的立体选择形成,制备了几种萘基异喹啉生物碱。
  • SnCl 4 -mediated oxidative biaryl coupling reaction of 1-naphthol and subsequent ring closure of 2,2′-binaphthol to the dinaphthofuran framework

    A simple method for the direct synthesis of 2,2′-binaphthols 2 and dinaphtho[1,2-b;2′,1′-d]furans 3 under mild conditions was developed, utilizing a biaryl coupling reaction via electron donor–acceptor complexes of 1-naphthols with SnCl4. Heating of the complex in a sealed tube for (18–24 h) afforded the corresponding o–o coupled product 2 in excellent yield. Prolonged reaction (56–65 h) under the
    利用电子供体-受体的联芳基偶联反应,开发了一种在温和条件下直接合成2,2'-联萘酚2和二萘并[1,2- b ; 2',1'- d ]呋喃3的简单方法1-萘酚与SnCl 4的配合物。该复合物在密封管中加热(18-24小时),得到相应的ö - ö偶联产物2的优良率。在相同条件下长时间反应(56–65小时)一步即可获得3的高收率。我们还发现,对于在C-1位上没有羟基以外的取代基的α-萘酚,区域选择性o –o进行了偶联反应。产物2a,2b和2g应该用作天然存在的3,3′-双juglone,3,3′-biplumbagin和艾力汀的合成中间体。
