    双核镁催化剂促进烯酮的不对称环氧化
    摘要:
    使用更便宜且无毒的碱土金属催化剂的不对称合成正成为主要依赖贵金属的传统催化方法的重要且可持续的替代方法。尽管有一些可持续的烯酮对映选择性环氧化方法,但为这些反应开发基于镁配合物的明确且有效的催化剂仍然是一项具有挑战性的任务。从这个角度来看,我们展示了手性双核镁配合物在各种缺电子烯酮的不对称环氧化中的应用。我们证明,原位生成的镁-苯酚复合物以高产率和优异的对映选择性(高达 99% ee)提供富含对映体的环氧乙烷。我们的广泛研究验证了该领域的文献数据,并为更好地了解控制氧合过程的因素提供了一步。精心制作的催化剂提供温和的反应条件和真正广泛的底物范围。

  • Enantioselective Epoxidation of Electrophilic Olefins by Using Glycosyl Hydroperoxides
    作者:Wioletta Kośnik、Wojciech Bocian、Lech Kozerski、Igor Tvaroška、Marek Chmielewski

    日期:2008.7.7
    Anomeric hydroperoxides derived from 3,4,6-tri-O-benzyl-galactose and glucose were used for enantioselective epoxidation of naphthoquinone (12), chalcone (13), (E)-1,2-dibenzoyl ethylene (14) and (E)-iso-butyryl-phenyl ethylene (15). In the presence of sodium hydroxide, the epoxidations showed exceptional high asymmetric induction. The exchange of sodium by a potassium ion resulted in a low asymmetric
    衍生自3,4,6-三-O-苄基-半乳糖和葡萄糖的端基氢过氧化物用于萘醌(12),查尔酮(13),(E)-1,2-二苯甲酰基乙烯(14)和( E)-异丁酰基-苯基乙烯(15)。在氢氧化钠存在下,环氧化显示出异常的高不对称诱导。通过钾离子交换钠导致低的不对称诱导。这些结果指出了抗衡离子的关键作用,并强烈建议在环氧化过程的过渡态中,氢过氧化物和烯烃这两种试剂均会发生碱性离子的配位。DFT B3LYP / 6-31G *水平上反应机理的理论研究与实验结果非常吻合。

  • Scoping the triphasic/PTC conditions for the Juliá–Colonna epoxidation reaction
    作者:Thomas Geller、Christa M. Krüger、H.-Christian Militzer
    DOI:10.1016/j.tetlet.2004.04.189
    日期:2004.6
    A new, highly efficient procedure for the Juliá–Colonna epoxidation is reported. Based on the original triphasic protocol it is shown that the co-catalysis of the reaction with phase transfer catalysts results in a dramatic increase of reactivity and sometimes also in a higher enantiomeric excess of product. The required amount of polyamino acid can be significantly reduced under the new conditions

  • Development of the Juliá asymmetric epoxidation reaction. Part 2. Application of the oxidation to alkyl enones, enediones and unsaturated keto esters
    作者:Wolfgang Kroutil、M. Elena Lasterra-Sánchez、Samuel J. Maddrell、Patrick Mayon、Phillip Morgan、Stanley M. Roberts、Steven R. Thornton、Christine J. Todd、Melek Tüter

    Polyleucine-based systems have been used to catalyse the asymmetric oxidation of a variety of alkyl enones 1-4,9-14, an enynone 16 and a dienone 17 to afford the corresponding epoxides 5-8, 18-26 in good to excellent yield and optical purity. A range of enediones 30-32, 34 and one unsaturated keto ester 33 have also been epoxidised stereoselectively to afford optically active epoxides 35-39. The epoxidations were carried out with basic peroxide as the oxidant; the polyleucine catalyst was prepared from leucine N-carboxyanhydride using 1,3-diaminopropane, water (employing a humidity cabinet) or a polystyrene immobilised amine as the initiator. Preliminary mass spectral data on material derived from L-leucine and 1,3-diaminopropane (DAP-PLL) suggest that the catalyst consists of material that contains 22 +/- 10 leucine residues.
