    名称:
    Fragmentation of Bicyclic γ-Silyloxy-β-hydroxy-α-diazolactones as an Approach to Ynolides
    摘要:
    Medium-sized ynolides were prepared by the Lewis acid-mediated fragmentation of bicyclic gamma-silyloxy-beta-hydroxy-alpha-diazolactones in which the C beta-C gamma bond is the ring fusion bond. Although these lactone fragmentation substrates reacted somewhat less efficiently than their carbocyclic counterparts, the fragmentation provided 11-membered ynolides in up to 84% yield. Unlike prior fragmentations of similar substrates, elevated temperatures were required to obtain optimum yields of the ynolide products. The ynolides reported herein have ring sizes of 10 or 11, which are the smallest reported to date.

  • A Simple and Effective Method for α-Hydroxylation of β-Dicarbonyl Compounds Using Oxone as an Oxidant without a Catalyst
    作者:Jun Yu、Jian Cui、Chi Zhang
    DOI:10.1002/ejoc.201000940
    日期:2010.12
    Oxone has been found to be a highly efficient reagent for the introduction of a hydroxy group at the α position of a variety of β-dicarbonyl compounds in the homogeneous solvent mixture of water and 1,4-dioxane at 60 °C.
    已发现 Oxone 是一种高效试剂,可在 60 °C 下在和 1,4-二恶烷的均相溶剂混合物中在各种 β-二羰基化合物的 α 位引入羟基。
  • Preparation of Acyloins by Cerium-Catalyzed, Direct Hydroxylation ofβ-Dicarbonyl Compounds with Molecular Oxygen
    作者:Jens Christoffers、Thomas Werner、Sven Unger、Wolfgang Frey
    DOI:10.1002/ejoc.200390075
    日期:2003.2
    We report the metal-catalyzed α-hydroxylation of a variety of cyclic and acyclic β-dicarbonyl compounds by molecular oxygen. The decisive advantage of this new method is the use of catalytic amounts of the nontoxic cerium salt CeCl3·7H2O in 2-propanol at ambient temperature. Most of the cyclic substrates 4a−4i give high yields of analytically pure products 5a−5i, and the workup procedure is simple
    我们报告了属催化的分子氧对各种环状和非环状 β-二羰基化合物的 α-羟基化。这种新方法的决定性优势是在环境温度下在 2-丙醇中使用催化量的无毒CeCl3·7H2O。大多数环状底物 4a-4i 产生高产率的分析纯产物 5a-5i,后处理程序是通过硅胶简单过滤。然而,无环二羰基化合物 4j-4p 的氧化伴随着副反应和分解,显着降低了产物 5j-5p 的产率。提出的机制与实验结果一致,特别是观察到的氧摄取。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003)
  • Cerium-Catalyzed Reaction ofβ-Dicarbonyl Compounds with Styrene and Atmospheric Oxygen
    作者:Jens Christoffers、Thomas Werner、Wolfgang Frey、Angelika Baro
    DOI:10.1002/ejoc.200300439
    日期:2003.12
    The cerium-catalyzed C−C coupling reaction of carbo- and heterocyclic β-dicarbonyl compounds 1 with styrenes 4, using oxygen (air) as the oxidant, at ambient temperature, is reported. The reaction afforded a mixture of diastereoisomeric hydroperoxides 5 which could be transformed into the unique dioxo compounds 6 by disproportionation of the peroxo function under treatment with acetyl chloride/pyridine

  • Iron-catalyzed hydroxylation of β-ketoesters with hydrogen peroxide as oxidant
    作者:Dongmei Li、Kristin Schröder、Bianca Bitterlich、Man Kin Tse、Matthias Beller
    DOI:10.1016/j.tetlet.2008.07.157
    日期:2008.10
    The hydroxylation of β-ketoesters was studied using simple iron catalysts and 30 wt % hydrogen peroxide as the terminal oxidant. The highest activity and yield were achieved in the presence of iron(III) chloride. Cyclic β-ketoesters could be smoothly hydroxylated in 75–90% yield. For linear β-ketoester and β-ketoamide, the chloro-substituted products were obtained.
    使用简单的催化剂和30 wt%的过氧化氢作为末端氧化剂,研究了β-酮酸酯的羟基化作用。在(III)的存在下获得了最高的活性和收率。环状β-酮酸酯可以75-90%的收率平稳地被羟基化。对于线性β-酮酸酯和β-酮酰胺,获得了取代的产物。
  • Formation of δ-Lactones by Cerium-Catalyzed, Baeyer–Villiger-Type Coupling of β-Oxoesters, Enol Acetates, and Dioxygen
    作者:Irina Geibel、Anna Dierks、Marc Schmidtmann、Jens Christoffers
    DOI:10.1021/acs.joc.6b01441
    日期:2016.9.2
    Formation of δ-lactones is observed when cyclopentanone-2-carboxylates are converted in a cerium-catalyzed reaction with α-aryl vinyl acetates under oxidative conditions. The products of this transformation possess a 1,4-dicarbonyl constitution together with a quaternary carbon center. Atmospheric oxygen is the oxidant in this process, which can be regarded as ideal from economic and ecological points
    环戊酮-2-羧酸酯在催化下与α-芳基乙酸乙烯酯在氧化条件下转化为时,可观察到δ-内酯的形成。该转化的产物具有1,4-二羰基结构以及季碳中心。大气中的氧气是该过程中的氧化剂,从经济和生态角度来看,这可以认为是理想的氧化剂。这种新的C–C偶联和氧化反应的其他优点是操作简便以及无毒廉价的CeCl 3 ·7 H 2的应用O作为前催化剂。提出了迄今为止前所未有的反应,它是通过1,2-二恶烷生物进行的,该衍生物在Baeyer-Villiger型途径中的氧碳正离子形成时分解。这种机理的观点得到了以下观察结果的支持:富电子的(供体取代的或杂芳族的)烯醇酯比缺电子的同类物具有更高的产率。除了作为副产物形成的1,4-二酮和α-羟基化的β-氧代酯外,δ-内酯的收率范围从中等到良(最高74%)。
