  • Distal γ‐C(sp <sup>3</sup> )−H Olefination of Ketone Derivatives and Free Carboxylic Acids
    作者:Han Seul Park、Zhoulong Fan、Ru‐Yi Zhu、Jin‐Quan Yu
    DOI:10.1002/anie.202003271
    日期:2020.7.27
    Reported herein is the distal γ‐C(sp3)−H olefination of ketone derivatives and free carboxylic acids. Fine tuning of a previously reported imino‐acid directing group and using the ligand combination of a mono‐N‐protected amino acid (MPAA) and an electrondeficient 2pyridone were critical for the γ‐C(sp3)−H olefination of ketone substrates. In addition, MPAAs enabled the γ‐C(sp3)−H olefination of free carboxylic
    本文报道了酮衍生物和游离羧酸的远端γ-C(sp 3 )-H烯化。微调先前报道的亚氨基酸导向基团并使用单N保护氨基酸(MPAA)和缺电子2-吡啶酮的配体组合对于γ-C(sp 3 )-H烯化至关重要酮底物。此外,MPAA 能够使游离羧酸发生 γ-C(sp 3 )-H 烯化反应,形成多种六元内酯。除了烷基羧酸之外,苄基 C(sp 3 )−H 键也可以通过 2-甲基苯甲酸衍生物一步功能化形成 3,4-二氢异香豆素结构。这些方案的实用性在大规模反应和 γ-C(sp 3 )−H 烯化产物的多样化中得到了证明。
  • Azapropellanes as phase-transfer catalysts—II
    作者:John M. McIntosh
    DOI:10.1016/0040-4020(82)80005-7
    日期:1982.1
    An improved synthesis of 1-azoniatricyclo[4.4.3.01,6]tridecane (2) and the preparation of the remaining member of the series, 1-azoniatricyclo[4.3.3.01,6]dodecane salts (3) have been achieved. Using a combination of 1H (at 400 MHz) and 13C NMR spectra has allowed the assignment of the signals in the well-resolved 1H spectra. The results indicate that 1 exists in the all-chair form which undergoes racemization
    已经实现了1-氮杂三环[4.4.3.0 1,6 ]十三烷(2)的改进的合成以及该系列的剩余成员1-氮杂三环[4.3.3.0 1,6 ]十二烷盐(3)的制备。通过结合使用1 H(在400 MHz下)和13 C NMR光谱,可以在良好分辨的1 H光谱中分配信号。结果表明1以全椅子形式存在,其以0.7秒-的速率常数通过环反转经历消旋化,并且进一步地,这些盐中的抗衡离子被限制为仅与四面体N原子的一个表面缔合。
  • Iron-catalysed allylation–hydrogenation sequences as masked alkyl–alkyl cross-couplings
    作者:Josef Bernauer、Guojiao Wu、Axel Jacobi von Wangelin
    DOI:10.1039/c9ra07604b
    日期:——
    organomagnesium reagents (alkyl, aryl) with simple allyl acetates proceeds under mild conditions (Fe(OAc)2 or Fe(acac)2, Et2O, r.t.) to furnish various alkene and styrene derivatives. Mechanistic studies indicate the operation of a homotopic catalyst. The sequential combination of such iron-catalysed allylation with an iron-catalysed hydrogenation results in overall C(sp3)–C(sp3)-bond formation that constitutes
    在温和条件下(Fe(OAc) 2或 Fe(acac) 2 , Et 2 O, rt),有机镁试剂(烷基、芳基)与简单的乙酸烯丙酯发生铁催化烯丙基化反应,得到各种烯烃和苯乙烯衍生物。机理研究表明了同伦催化剂的运作。这种铁催化烯丙基化与铁催化氢化的顺序组合导致整体C(sp 3 )–C(sp 3 )-键形成,这构成了具有挑战性的与烷基卤化物的直接交叉偶联方案的有吸引力的替代方案。
  • Regio‐ and Diastereoselective Copper‐Catalyzed Carbomagnesiation for the Synthesis of Penta‐ and Hexa‐Substituted Cyclopropanes
    作者:Yair Cohen、André U. Augustin、Laura Levy、Peter G. Jones、Daniel B. Werz、Ilan Marek
    DOI:10.1002/anie.202102509
    日期:2021.5.17
    Despite the highly strained nature of cyclopropanes possessing three vicinal quaternary carbon stereocenters, the regio‐ and diastereoselective copper‐catalyzed carbomagnesiation reaction of cyclopropenes provides an easy and efficient access to these novel persubstituted cyclopropyl cores with a complete regio‐ and diastereoselectivity.
