    芳基铜试剂对2-溴环己-2-烯醇衍生酯的烯丙基取代及衍生抗SN2'产物的合成利用
    摘要:
    研究了衍生自 2-溴环己-2-烯醇的酯与 PhMgBr 基铜试剂的烯丙基取代,以发现与磷酸二乙酯的高抗 SN 2' 选择性,而其他酯如吡啶甲酸酯、乙酸酯和甲磺酸酯导致部分外消旋化或起始酯的回收。该方案应用于衍生自 2-Me-​​4-MeOC 6 H 3 MgBr 和 CuBr·SMe 2 的铜试剂,并裂解抗 SN 2' 产物的烯烃部分以合成广藿香醇。

    Overcoming Equilibrium Issues with Carbonyl Reductase Enzymes
    摘要:
    We report herein the screening, optimisation and scale up to 100 g of a bioreduction process that employs an in situ product removal (ISPR) technique to overcome the inherent equilibrium problem associated with the coupled-substrate approach to biocatalytic carbonyl reduction. This technique allowed the valuable chiral alcohol, (S)-2-bromo-2-cyclohexen-1-ol, to be isolated in 88% yield and 99.8% ee without the need for further purification, validating the general applicability of this experimental setup.

  • Synthesis of Ketones and Esters from Heteroatom-Functionalized Alkenes by Cobalt-Mediated Hydrogen Atom Transfer
    作者:Xiaoshen Ma、Seth B. Herzon
    DOI:10.1021/acs.joc.6b01709
    日期:2016.10.7
    Cobalt bis(acetylacetonate) is shown to mediate hydrogen atom transfer to a broad range of functionalized alkenes; in situ oxidation of the resulting alkylradical intermediates, followed by hydrolysis, provides expedient access to ketones and esters. By modification of the alcohol solvent, different alkyl ester products may be obtained. The method is compatible with a number of functional groups including
    已显示双(乙酰丙酮酸)钴介导氢原子转移到各种官能化烯烃中。所得烷基自由基中间体的原位氧化,然后水解,可方便地获得酮和酯。通过改性醇溶剂,可以获得不同的烷基酯产物。该方法与许多官能团兼容,包括链烯基卤化物,硫化物,三氟甲磺酸酯和膦酸酯,为乙烯基硅烷的Tamao-Fleming氧化和Arndt-Eistert同系物提供了温和而实用的替代方法。
  • A stable and easily prepared catalyst for the enantioselective reduction of ketones. Applications to multistep syntheses

    recently described a new method for the catalytic enantioselective reduction of ketones to chiral secondary alcohols.' The stoichiometric reagent in the reduction is borane (usually 0.6 molfmol of ketone), and the catalyst is a chiral oxazaborolidine such as 1 (0.05-0.1 molfmol of ketone). Excellent enantioselectivities, easy recoverability of the chiral catalyst predecessor, near quantitative yields, short
    我们最近描述了一种将酮催化对映选择性还原为手性仲醇的新方法。还原反应的化学计量试剂为硼烷(通常为0.6molfmol酮),催化剂为手性氧氮杂硼烷如1(0.05-0.1molfmol酮)。优异的对映选择性、手性催化剂前身的易回收性、接近定量的产率、较短的反应时间(在 23°C 下为几分钟)以及产品绝对构型的可预测性有助于该 (CBS') 工艺的出色效用。本文报告了该领域在改进实用性和重要应用方面的几项后续发展。与对空气和水分均敏感的 1 相比,B-甲基化恶唑硼烷2可在室温下储存在密闭容器中,并在空气中称重或转移。催化剂 2 也比催化剂 1 更容易制备。 (S)-的反应

  • Enantioselective Synthesis of Cyclic, Quaternary Oxonitriles
    作者:Yakup Güneş、M. Fatih Polat、Ertan Sahin、Fraser F. Fleming、Ramazan Altundas
    DOI:10.1021/jo1011202
    日期:2010.11.5
    Quaternary oxonitriles are stereoselectively generated from the union of five-, six-, and seven-membered 2-chloroalkenecarbonitriles with chiral alcohols via a Claisen rearrangement. The strategy rests on a new conjugate addition−elimination of allylic alkoxides to 2-chlorocycloalkenecarbonitriles to afford substituted 2-alkoxyalkenenitriles. Subsequent thermolysis unmasks a cyclic oxonitrile while
    五元,六元和七元的2-氯烯烃腈与手性醇通过克莱森重排的结合立体选择性地生成季腈。该策略基于新的共轭加成-将烯丙基醇盐消除到2-氯环烯腈中,得到取代的2-烷氧基烯腈。随后的热解反应会掩盖环状氧腈,同时选择性地形成对映体比率通常大于9:1的新季铵中心。整体烷基化策略解决了对映选择性地生成受阻的四级中心同时安装酮,腈和烯烃官能团的挑战。
  • Synthesis of <i>trans</i>-2,6-Disubstituted Cyclohexanones through Allylic Substitution
    作者:Yuichi Kobayashi、Chao Feng、Atsushi Ikoma、Narihito Ogawa、Takayuki Hirotsu
    DOI:10.1021/ol403472y
    日期:2014.2.7
    cyclohexanones were synthesized with high regio- and stereoselectivity by allylic substitution followed by ozonolysis. Both alkyl and aryl groups were successfully installed to the cyclohexane ring. The stereochemistry of the SN2′ products was determined to be controlled by the pre-existing chirality on the ring. The present method is highlighted by the synthesis of enantiomerically enriched cyclohexanones
