  • Novel Route to Enantiopure 2,2'-Diaryl-1,1'-binaphthalenes by Stereoconservative Suzuki Arylation at Positions 2 and 2'
    作者:Henrich Brath、Margaréta Dubovská、Michal Juríček、Peter Kasák、Martin Putala
    DOI:10.1135/cccc20041517
    日期:——

    The Suzuki arylation of enantiopure 2,2'-diiodo-1,1'-binaphthalene affords the 2,2'-diarylated products in considerable yields (up to 52%), however, significantly racemized. The reversed-polarity approach, using novel enantiopure 1,1'-binaphthalene-2,2'-diyldiboronic acid, prepared either by resolution or by stereoconservative boronation, allowed, after optimization of coupling conditions, to obtain the model 2,2'-ditolylated product in good yield (56%) as well, but in addition, without impairing of enantiomeric purity (i.e. stereoconservatively). The developed synthetic approach was found to be an expedient method for the synthesis of enantiopure 2,2'-diaryl-1,1'-binaphthalenes, especially for those with electron-neutral and electron-deficient poor aryl groups. Observing that the diboronic acid decomposes by hydrodeboronation under the reaction conditions, 2-aryl-1,1'-binaphthalenes were isolated as the main products from the reaction with less reactive electron-rich aryl iodides.

    对手性纯的2,2'-二-1,1'-联萘进行促芳基化反应,可以得到2,2'-二芳基化产物,收率相当可观(高达52%),但会发生明显的拉仑化。采用反向极性方法,使用新型的手性纯1,1'-联萘-2,2'-二基硼酸,通过拆分或立体保持化反应制备,经过偶联条件的优化,可以获得模型2,2'-二对甲苯基化产物同样有良好的收率(56%),同时不影响对映体纯度(即立体保持)。这种合成方法被发现是一种方便的方法,特别适用于合成手性纯的2,2'-二芳基-1,1'-联萘,尤其适用于带有电子中性和电子亏缺的芳基团。观察到硼酸在反应条件下通过氢去反应分解,与反应性较差的电子富集芳基发生反应时,主要产物是2-芳基-1,1'-联萘
  • Synthesis of a Chiral Borate Counteranion, Its Trityl Salt, and Application Thereof in Lewis‐Acid Catalysis
    作者:Phillip Pommerening、Jens Mohr、Jonas Friebel、Martin Oestreich

    日期:2017.4.26
    The preparation of a chiral derivative of [B(C6F5)4]– in which the fluorine atom in the para position of each of the C6F5 groups is replaced by a 1,1′-binaphthalen-2-yl group is described. The new counteranion was isolated as its lithium, sodium, and trityl salts. The chiral trityl salt was then used as a catalyst in selected counteranion-directed Diels–Alder reactions and a Mukaiyama aldol addition
    描述了 [B(C6F5)4]- 的手性衍生物的制备,其中每个 基团的对位原子被 1,1'-联萘-2-基基团取代。新的抗衡阴离子以其盐、钠盐和三苯甲基盐的形式被分离出来。然后将手性三苯甲基盐用作选定的抗衡阴离子导向的 Diels-Alder 反应和 Mukaiyama 醛醇加成反应的催化剂,但没有实现不对称诱导。将手性三苯甲基盐应用于通过从氢硅烷到碳氢化物转移产生阳离子失败,可能是由于硼酸盐中相对富电子的基与阳离子亲电试剂不相容。
  • Axially Chiral Borinic Acid Catalysts: Design, Synthesis, and Application in Alkylative Desymmetrization of 1,2-Diols

    A novel chiral borinic acid (CBA), an organocatalyst possessing a binaphthyl skeleton, was designed and synthesized. The synthesis of CBA was achieved with a 72% yield in four steps starting with optically pure 1,1′-bi-2-naphthol. The asymmetric catalytic activity was investigated in the desymmetrization of meso-1,2-diol.
