    Palladium-Catalyzed Cyclization of 1,ω-Dienols:  Multiple Ways to Intramolecularly Trap a Carbocation
    摘要:
    The tandem catalytic cyclization-rearrangement of 1,omega-dien-3-ols by palladium(II) produces different types of products, depending on the structure of starting material. The pinacol rearrangement, benzannulation, and oxy-Cope rearrangement are major pathways of transforming the putative sigma-alkylpalladium carbocation. Turnover of the cyclization is achieved by beta-hydride elimination and reoxidation of palladium with benzoquinone. The overall course of the reaction is very sensitive to small changes in the substrate structure.

  • Oxidative Cyclization Reactions: Controlling the Course of a Radical Cation-Derived Reaction with the Use of a Second Nucleophile
    作者:Alison Redden、Robert J. Perkins、Kevin D. Moeller
    DOI:10.1002/anie.201308739
    日期:2013.12.2
    Construction of new ring systems: Oxidative cyclizations (see picture; RVC=reticulated vitreous carbon) have been conducted that use two separate intramolecular nucleophiles to trap an enol ether‐derived radical cation intermediate. The reactions provide a means for rapidly trapping the radical cation intermediate in a manner that avoids competitive decomposition reactions.
    新环系统的构建:已经进行了氧化环化(见图;RVC=网状玻璃碳),使用两个单独的分子内亲核试剂来捕获烯醇醚衍生的自由基阳离子中间体。该反应提供了一种以避免竞争性分解反应的方式快速捕获自由基阳离子中间体的手段。
  • Catalytic Intramolecular Coupling of Ketoalkenes by Allylic C( <i>sp</i> <sup>3</sup> )−H Bond Cleavage: Synthesis of Five‐ and Six‐Membered Carbocyclic Compounds
    作者:Tsuyoshi Mita、Masashi Uchiyama、Yoshihiro Sato
    DOI:10.1002/adsc.201901533
    日期:2020.3.17
    In the presence of a catalytic amount of cobalt(II) acetylacetonate/Xantphos in combination with trimethylaluminum, various ketoalkenes underwent an intramolecular cyclization reaction triggered by cleavage of the allylic C(sp3)−H bond, affording carbocyclic compounds with high regio‐ and diastereoselectivity. Mono‐, bi‐, and tricarbocyclic compounds were produced in good yields. One of the products
    在催化量的乙酰丙酮钴(II)/ Xantphos与三甲基铝结合存在的情况下,各种酮基烯烃经历了烯丙基C(sp 3)-H键断裂引发的分子内环化反应,从而提供了具有高区域和高碳环含量的碳环化合物非对映选择性。单,双和三碳环化合物的收率很高。由此获得的产物之一通过四个简单步骤被衍生为曲马多。值得注意的是,这些分子内环化反应是在连接的碳链上没有宝石二取代基的情况下发生的(没有索普-英戈尔德效应)。
  • Electroorganic Chemistry. XXXIV. Novel Intramolecular Cyclization through Anodic Oxidation of Enol Acetates
    作者:Tatsuya Shono、Ikuzo Nishiguchi、Shigenori Kashimura、Masahisa Okawa
    DOI:10.1246/bcsj.51.2181
    日期:1978.7
    The anodic oxidation of 1-acetoxy-1,6-heptadiene homologues in acetic acid gave mainly intramolecular cyclization products, cyclohexenyl ketones. The cyclization takes place through the electrophilic attack of the cationic center generated from the enol ester moiety to the double bond.

  • A Convenient Synthesis of Condensed Cyclopentane System. Annelation by Intramolecular 1,3-Dipolar Addition of Nitrones

    DOI:10.1246/bcsj.54.1777
    日期:1981.6
    Intramolecular 1,3-dipolar addition reactions of nitrones were investigated. Four alkenyl nitrones were studied: 2-allyl-, 2-(3-butenyl)-, 2-(4-pentenyl)-, and 2-(9-decenyl)-N-methylcyclohexanimine N-oxides. Among these, 2-(3-butenyl)-N-methylcyclohexanimine N-oxide was found to cyclize most smoothly, giving a perhydroindene derivative as a single regio- and stereoisomer. A perhydroazulene derivative

    A highly regioselective, one-step dehydrogenation of α-substituted cyclic ketones in the presence of 2,3-dichlorobenzo-5,6-dicyano-1,4-benzoquinone is described.
