  • Enantioselective Oxy-Heck-Matsuda Arylations: Expeditious Synthesis of Dihydrobenzofuran Systems and Total Synthesis of the Neolignan (−)-Conocarpan
    作者:Allan R. Silva、Ellen C. Polo、Nelson C. Martins、Carlos Roque D. Correia
    DOI:10.1002/adsc.201701278
    日期:2018.1.17
    process is demonstrated by a concise total synthesis of the neolignan (−)‐conocarpan. X‐ray diffraction of an advanced brominated intermediate in the route to (−)‐conocarpan has allowed the unequivocal assignment of the absolute stereochemistry of the oxy‐Heck–Matsuda aryldihydrobenzofuran products. A rationale for the mechanism operating in these enantioselective oxy‐Heck–Matsuda reactions is also presented
    这项工作公开了使用多种苯乙烯烯烃生成手性二氢苯并呋喃的有效对映选择性氧-Heck-Matsuda反应的第一个实例。该反应以中等至良好的产率进行,具有高反式使用N,N-配体嘧啶-双恶唑啉(PyriBox)在90:10的对映选择性中具有非对映选择性(高达20:1)。oxy-Heck-Matsuda反应在温和的条件下和较低的催化剂载量下进行。新木脂素(-)-角果胶的简明全合成证明了该方法的可行性和实用性。在通往(-)-香柏树醇的途径中,对高级溴化中间体进行X射线衍射分析,使得对氧-赫克-松田芳基二氢苯并呋喃产品的绝对立体化学的明确分配成为可能。还介绍了在这些对映选择性氧-Heck-Matsuda反应中起作用的机理的基本原理。
  • Synthesis of (−)-conocarpan by two routes based on radical cyclization and establishment of its absolute configuration

    terminal double bond. The two routes differ in their degree of stereoselectivity. The absolute configuration originally assigned to (+)-conocarpan had previously been called into question on the basis of empirical chiroptical rules; the present chemical work confirms the need for revision, and the assigned absolute configurations of several compounds correlated with (+)-conocarpan must also be changed.
    描述了生物活性新木脂素(-)-树果皮总合成的两种独立途径。第一个(98%ee)是基于在苯环上进行正式的自由基环化,并涉及在6元环内约束的双键上的5-exo-trigonal闭合。第二种途径(88%ee)较短,基于芳基在侧链双键上的5-外三角环化。两种途径的立体选择性程度不同。最初分配给(+)-角果皮的绝对构型以前是根据经验的按摩学规则而受到质疑的。目前的化学工作证实需要修订,并且还必须更改与(+)-棕榈果糖相关的几种化合物的绝对构型。
  • Asymmetric Synthesis of Neolignans (−)-<i>epi</i>-Conocarpan and (+)-Conocarpan via Rh(II)-Catalyzed C−H Insertion Process and Revision of the Absolute Configuration of (−)-<i>epi</i>-Conocarpan

    日期:2009.6.5
    Catalytic asymmetric synthesis of neolignan natural products (−)-epi-conocarpan and (+)-conocarpan has been achieved by exploiting an enantio- and diastereoselective intramolecular C−H insertion reaction to construct a cis-2-aryl-2,3-dihydrobenzofuran ring system as a key step. The C−H insertion reaction of 5-bromoaryldiazoacetate catalyzed by Rh2(S-PTTEA)4, a new dirhodium(II) carboxylate complex that

    Heterogeneous photocatalysis is considered as an ecofriendly and sustainable approach for addressing energy and environmental persisting issues. Recently, heterogeneous photocatalysts based on covalent organic frameworks (COFs) have gained considerable attention due to their remarkable performance and recyclability in photocatalytic organic transformations, offering a prospective alternative to homogeneous
    多相光催化被认为是解决能源和环境持续问题的一种生态友好和可持续的方法。最近,基于共价有机骨架(COFs)的多相光催化剂因其在光催化有机转化中的卓越性能和可回收性而受到广泛关注,为基于贵金属/有机染料的均相光催化剂提供了一种有前途的替代方案。在此,我们报告了Hex-Aza-COF-3作为一种无金属、可见光激活和可重复使用的多相光催化剂,用于合成 2,3-二氢苯并呋喃,作为一种药学相关的结构基序,通过酚类与烯烃的选择性氧化 [3+2] 环加成反应。此外,我们证明了通过 [3+2] 环加成反应合成天然产物 (±)-conocarpan 和 (±)-紫檀素是使用Hex-Aza-COF-3作为多相光催化剂的重要步骤。有趣的是,吩嗪和六氮杂苯并菲作为刚性杂环单元存在于Hex-Aza-COF-3中加强共价键,增强可见光区的吸收,并缩小能带,导致光催化反应中优异的活性、电荷传输、稳定性和可回收性,这从超快
  • Synthesis of 2,3-Dihydrobenzofurans by Mn(OAc)<sub>3</sub>-Based Oxidative Cycloaddition of 2-Cyclohexenones with Alkenes. Synthesis of (±)-Conocarpan
    作者:Barry B. Snider、Luning Han、Chaoyu Xie
    DOI:10.1021/jo9708506
    日期:1997.10.1
    Oxidative cycloaddition of a 2-cyclohexenone or alpha-tetralone and an alkene with dried Mn(OAc)(3) in benzene at 80-140 degrees C provides a general route to dihydrobenzofurans 15 and dihydronaphthofurans 17. Although the yields are modest, this one-pot reaction provides simple access to these compounds, which have previously been prepared by multistep routes. Oxidative cycloaddition of 2-cyclohexenones with beta-methylstyrenes provides a new route to benzofuranoid neolignans, which was applied to the synthesis of conocarpan (22). The formation of 2-acetoxyhexanedioic acids 27 and 47 from acetoxylation of 2-cyclohexenones in HOAc, but not in benzene, opens up a new class of Mn(OAc)(3) reactions and explains Watt and Demir's discovery that much higher yields of alpha'-acetoxy enones are obtained in benzene than in HOAc.
