  • An Electrophilic Bromine Redox Catalysis for the Synthesis of Indole Alkaloid Building Blocks by Selective Aliphatic C−H Amination
    作者:Julien Bergès、Belén García、Kilian Muñiz
    DOI:10.1002/anie.201808939
    日期:2018.11.26
    A new homogeneous bromine(−I/I) redox catalysis is described, which is based on monomeric bromine(I) compounds containing transferable phthalimidato groups. These catalysts enable intermolecular C−H amination reactions at previously unaccessible aliphatic positions and thus enlarge the synthetic potential of direct C−N bond formation, including its application in the synthesis of alkaloid building
    描述了一种新的均相(-I / I)氧化还原催化,其基于含有可转移邻苯二甲酰亚胺基的单体(I)化合物。这些催化剂能够在以前无法接近的脂肪族位置进行分子间CH化反应,从而扩大了直接CN键形成的合成潜力,包括其在生物碱结构单元合成中的应用。这方面通过一种新的合成方法来证明。除了开发催化剂体系外,还充分阐明了所涉及的(I)关键催化剂的结构,包括通过X射线分析得出的结果。
  • Application of the Palladium(0)-Catalyzed Ullmann Cross-Coupling Reaction in a Total Synthesis of (±)-Aspidospermidine and thus Representing an Approach to the Lower Hemisphere of the Binary Indole - Indoline Alkaloid Vinblastine

    reaction to give the bicyclic system 5. In contrast, the related compound 46, incorporating tethered enone and azide moieties, engaged in an intramolecular 1,3-dipolar cycloaddition reaction to give, presumably via an intermediate triazoline, the isolable and ring-fused aziridine 47. This was then converted, over two steps, into the previously reported tetrahydrocarbazole 4. Application of established protocols

  • Flow thermolysis rearrangements in the indole alkaloid series: 1,2-dehydroaspidospermidine
    作者:Georgette Hugel、Daniel Royer、Francoise Sigaut、Jean Levy
    DOI:10.1021/jo00015a013
    日期:1991.7
    Flow thermolysis of 1,2-dehydroaspidospermidine (1) at various temperatures allowed isolation of all four predictable rearrangement products, namely indolenines 2 and 3 and indoles 4 and 5. The structures of the rearranged products were confirmed by chemical and spectroscopic means, particularly HMBC and HMQC NMR techniques.
