  • Palladium/Acid Relay Catalyzed Tandem Heck Coupling/6‐Endo Cyclization between ortho‐Halogenated Benzoates and Unactivated Terminal Alkenes for the Synthesis of 1‐Isochromanones
    作者:Zhenkang Wen、Xiaomin Ge、Zekai Zhao、Jianbin Chao
    DOI:10.1002/adsc.201801507
    日期:——
    We report a unique and expeditious route to synthesize 1‐isochromanone derivatives through palladium catalyzed tandem Heck coupling/6‐endo hydroacyloxylation cyclization between readily available ortho‐halogenated benzoates and unactivated alkenes. Various 2‐bromo or 2‐iodo benzoates can be coupled efficiently with a broad range of alkenes to afford functionalized 1‐isochromanones in high yields. Significantly
    我们报告了一种独特且快速的途径,可通过钯催化的串联Heck偶联/ 6-内羟基加氢酰氧基化环化反应在易于获得的邻卤代苯甲酸酯和未活化烯烃之间合成1-异苯并二氢呋喃酮衍生物。各种2-溴或2-碘苯甲酸酯可以有效地与各种烯烃偶联,从而以高收率提供官能化的1-异铬酮。重要的是,这种经济高效且易于操作的合成方法将在合成和药物化学中具有广阔的应用前景。

    efficient benzylic C–H oxygenations of cyclic ethers using oxygen as an oxidant. This oxidation reaction utilizes α-angelica lactone as a low cost/low molecular weight catalyst. The optimized reaction conditions allow the synthesis of valued isocoumarins and phthalides from readily available precursors in good yields. Mechanistic studies indicate that the reaction pathway likely involves a radical process

  • Oxidaition of cyclic benzylic ethers by an electronically tuned nitroxyl radical
    作者:Shohei Hamada、Kyoko Yano、Yusuke Kobayashi、Takeo Kawabata、Takumi Furuta
    DOI:10.1016/j.tetlet.2021.153404
    日期:2021.10
    The reactivity of an electronically tuned nitroxyl radical catalyst for the oxidation of cyclic benzylic ethers has been investigated. The oxidation of phthalan resulted in oxidative cleavage of the saturated ring to give an aromatic dialdehyde. Additionally, oxidation of isochromans afforded isochromanones, which are often seen in natural products, in a rapid manner.
