  • Thiyl radical promoted iron-catalyzed-selective oxidation of benzylic sp<sup>3</sup> C–H bonds with molecular oxygen
    作者:Shasha Geng、Baojian Xiong、Yun Zhang、Juan Zhang、Yun He、Zhang Feng
    DOI:10.1039/c9cc06584a
    日期:——
    A ligand-free iron-catalyzed method for the oxygenation of benzylic sp3 C–H bonds by molecular oxygen (1 atm) using a thiyl radical as a cocatalyst has been developed. This transformation provides a facile access to amides, esters and ketones from readily accessible corresponding amines, ethers and alkanes. It features high regioselectivity, mild oxidative conditions and excellent functional group
    已开发出一种无配体的铁催化方法,该方法使用噻吩基作为助催化剂,通过分子氧(1 atm)氧化苄基sp 3 C–H键。该转化提供了从容易获得的相应的胺,醚和烷烃容易地获得酰胺,酯和酮的途径。它具有高区域选择性,温和的氧化条件和出色的官能团相容性,为复杂分子的位点选择性官能化提供了很好的机会。初步的机理研究表明,该反应可能不会经历苄基阳离子中间途径,并且产物中的羰基氧原子可能源自分子氧。
  • A g-C<sub>3</sub>N<sub>4</sub>-based heterogeneous photocatalyst for visible light mediated aerobic benzylic C–H oxygenations
    作者:Pengxin Geng、Yurong Tang、Guanglong Pan、Wentao Wang、Jinchuan Hu、Yunfei Cai
    DOI:10.1039/c9gc02870f
    日期:——
    A metal-free heterogeneous photocatalytic system has been developed for highly efficient benzylic C–H oxygenations using oxygen as an oxidant. This visible light mediated oxidation reaction utilizes graphitic carbon nitride (g-C3N4) as a recyclable, nontoxic and low cost photocatalyst. Mild reaction conditions allow for the generation of synthetically and biologically valued isochromannones, phthalides
    已开发出一种无金属的非均相光催化系统,用于使用氧气作为氧化剂的高效苄基CH氧化。这种可见光介导的氧化反应利用石墨碳氮化物(gC 3 N 4)作为可回收,无毒且低成本的光催化剂。温和的反应条件可从易于获得的烷基芳族前体中以高收率生成合成和生物学上有价值的异苯并二氢醌,邻苯二甲酸,异喹啉酮,异吲哚啉酮和氧杂蒽。gC 3 N 4的异质性催化系统可轻松回收和循环利用,并可多次使用而不会损失活性。通过在生物活性和具有药物价值的靶标合成中的应用,进一步证明了这种“绿色”方法的综合效用。
  • α-Angelica lactone catalyzed oxidation of benzylic sp<sup>3</sup> C–H bonds of isochromans and phthalans
    作者:Thanusha Thatikonda、Siddharth K. Deepake、Pawan Kumar、Utpal Das
    DOI:10.1039/d0ob00729c

    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
