    摘要:
    据报道,氟离子催化了甲基取代烯丙基硅烷的异构化反应。在该反应中,获得了一种烯丙基硅烷的区域异构体,其中硅原子与烯丙基中取代程度较低的碳原子结合。因此,该反应可作为烯丙基硅烷区域选择性合成的新途径。

  • Photoinduced Cross-Coupling of Aryl Iodides with Alkenes
    作者:Yuliang Liu、Haoyu Li、Shunsuke Chiba
    DOI:10.1021/acs.orglett.0c03935
    日期:2021.1.15
    A protocol for photoinduced cross-coupling of aryl iodides having polar π-functional groups or elongated π-conjugation with alkenes has been developed. The radical cascade mechanism involving generation of aryl radicals via C–I bond homolysis of photoexcited aryl iodides and their subsequent addition to alkenes is proposed. The method enables iodide-selective cross-coupling over other halogen leaving
    已经开发出用于光诱导的具有极性π-官能团的芳基碘的交叉偶联或延长的与烯烃的π-共轭的方案。提出了一种自由基级联机制,涉及通过光激发的芳基碘化物的C–I键均质化及其随后添加到烯烃中的芳基自由基的产生。该方法使得碘化物与其他卤素离去基团的选择性碘交叉偶联具有在芳烃和烯烃基团上的官能团相容性。
  • On the Stereoselectivity of γ-Lactol Substitutions with Allyl- and Propargylsilanes − Synthesis of Disubstituted Tetrahydrofuran Derivatives
    作者:Andreas Schmitt、Hans-Ulrich Reißig
    DOI:10.1002/1099-0690(200012)2000:23<3893::aid-ejoc3893>3.0.co;2-e
    日期:2000.12
    Monosubstituted γ-lactols 1a−1c, 3a−3c and 4a−4c, as well as disubstituted γ-lactol 5 and the γ-hydroxy-substituted γ-lactone 6, were transformed into disubstituted tetrahydrofuran derivatives by treatment with allyl- and propargylsilanes in the presence of Lewis acids. The diastereoselectivities were moderate to excellent and are interpreted by application of the Felkin−Anh model to cyclic oxocarbenium
    单取代的 γ-乳醇 1a-1c、3a-3c 和 4a-4c,以及双取代的 γ-乳醇 5 和 γ-羟基取代的 γ-内酯 6,通过用烯丙基-和炔丙基硅烷处理转化为双取代的四氢呋喃衍生物。路易斯酸的存在。非对映选择性中等至极好,可以通过将 Felkin-Anh 模型应用于环状氧碳鎓离子来解释。讨论了中间体构象异构体之间平衡的影响。在此基础上可以解释 4-取代 γ-内酯 3 令人惊讶的高非对映选择性。
