    Copper‐Catalyzed Aza‐Sonogashira Cross‐Coupling To Form Ynimines: Development and Application to the Synthesis of Heterocycles
    摘要:
    AbstractNitrogen‐substituted alkynes, such as ynamines and ynamides, are versatile synthetic building blocks. Ynimines bearing additional nucleophilic and electrophilic centers relative to ynamines and ynamides are expected to have high synthetic potential. However, their chemical reactivity remains unexplored owing mainly to the lack of synthetic accessibility. We report herein a versatile copper‐catalyzed synthesis of ynimines from readily available O‐acetyl ketoximes and terminal alkynes. A wide range of O‐acetyl ketoximes derived from diaryl ketones, aryl alkyl ketones and dialkyl ketones underwent cross‐coupling with a diverse set of terminal alkynes to afford the ynimines in good to excellent yields. An unprecedented [5+1] heteroannulation reaction exploiting the reactivity of the ynimine generated in situ was subsequently developed for the synthesis of medicinally important heterocycles, including isoquinolines, azaindoles, azabenzofurans, azabenzothiophenes and carbolines.

  • Direct Synthesis of Mono-α-arylated Ketones from Alcohols and Olefins via Ni-Catalyzed Oxidative Cross-Coupling
    作者:Peng-Fei Yang、Wei Shu
    DOI:10.1021/acs.orglett.0c02340
    日期:2020.8.7
    Controlled synthesis of α-monoarylated ketones is significant yet challenging due to the site-selectivity issues and nonproductive overarylation reactions. Herein, we reported the direct synthesis of α-arylated ketones enabled by Ni-catalyzed dehydrogenative cross-coupling reaction cascade between alcohols and olefins. The use of readily available and cost-effective alcohols and olefins provides a
    由于位点选择性问题和非生产性的过度芳基化反应,α-单芳基化酮的受控合成是重要的,但具有挑战性。在本文中,我们报道了通过醇和烯烃之间的镍催化的脱氢交叉偶联反应级联反应可以直接合成α-芳基化酮。使用容易获得且具有成本效益的醇和烯烃可直接获得高收率的单芳基化酮,且具有独特的选择性,而无需使用任何高级合成中间体。

    heterogeneous catalytic method for the methylation of C–H bonds in alcohols, ketones, and indoles with methanol under oxidant-free conditions using a Pt-loaded carbon (Pt/C) catalyst in the presence of NaOH is reported. This catalytic system is effective for various methylation reactions: (1) the β-methylation of primary alcohols, including aryl, aliphatic, and heterocyclic alcohols, (2) the α-methylation
    一种通用,选择性和可循环利用的非均相催化方法,是在无氧化剂的条件下,使用载有Pt的碳(Pt / C)催化剂在NaOH的存在下,用甲醇在醇,酮和吲哚中的C–H键进行甲基化的方法是报告。该催化体系对各种甲基化反应均有效:(1)伯醇(包括芳基,脂肪族和杂环醇)的β-甲基化;(2)酮的α-甲基化;(3)选择性C3-吲哚的甲基化。反应由借氢机制驱动。反应开始于将醇脱氢得到醛,然后将其与亲核试剂(醛,酮或吲哚)进行缩合反应,然后通过Pt–H物种将缩合产物氢化以生成所需的醛。产品。在这项研究中探讨的所有甲基化反应中,Pt / C催化剂的周转率均比以前报道的其他均相催化体系高得多。而且,证明了如在不同金属表面上的密度泛函理论计算所揭示的,Pt的高催化活性可以根据氢在金属表面上的吸附能而合理化。

    The Phetochemical reactions of several families of ketones adsorbed on various forms of silica have been investigated. The influence of surface coverage, silica average pore diameter, temperature, applied magnetic fields, and additives on the product distributions have been determined. The results are consistent with a model in which the silica surface consists of two major regions, one consisting
    已经研究了吸附在各种形式的二氧化硅上的几族酮的苯醚化学反应。已经确定了表面覆盖率,二氧化硅平均孔径,温度,施加的磁场和添加剂对产品分布的影响。结果与模型一致,在该模型中,二氧化硅表面由两个主要区域组成,一个区域由较强的结合位点(活性硅烷醇基团)组成,另一个由较弱的结合位点(游离硅烷醇基团)组成。这两种类型的位点的相对比例与二氧化硅的孔径有关,较小的孔与较大部分的较强的结合位点相关,而较大的孔与较小部分的较强的结合位点相关。在低覆盖率的情况下,酮在两个结合位点之一中的初始位置是确定产物分布的重要因素。关于通过扩散反射吸收光谱法研究的吸附在二氧化硅上的酮的时间分辨光谱学,报道了一些初步结果。
  • Rhenium(I)-Catalyzed C-Methylation of Ketones, Indoles, and Arylacetonitriles Using Methanol
    作者:Sujan Shee、Sabuj Kundu
    DOI:10.1021/acs.joc.1c00376
    日期:2021.5.7
    A ReCl(CO)5/MeC(CH2PPh2)3 (L2) system was developed for the C-methylation reactions utilizing methanol and base, following the borrowing hydrogen strategy. Diverse ketones, indoles, and arylacetonitriles underwent mono- and dimethylation selectively up to 99% yield. Remarkably, tandem multiple methylations were also achieved by employing this catalytic system.

    作者:Mihai S. Viciu、Romain F. Germaneau、Steven P. Nolan
    DOI:10.1021/ol026745m
    日期:2002.11.1
    A number of palladium-N-heterocyclic carbene (NHC) complexes were found to be active catalysts for the arylation of ketones. A large number of substrates, both aryl halides and ketones, are compatible with the reaction conditions. The ketone arylation reactions are achieved with low catalyst loading in short reaction times using aryl chlorides and triflates as reactive partners. [reaction: see text]
