    Synthesis of a 2,7-Dioxatricyclo[4.2.1.03,8]nonane:  A Model Study for Possible Application in a Synthesis of Dictyoxetane
    摘要:
    A method for the synthesis of the 2,7-dioxatricyclo[4.2.1.0(3,8)]nonane ring system characteristic of the marine diterpene dictyoxetane has been developed. This method utilizes a dipolar cycloaddition of a 3-oxidopyrylium salt to create the carbon skeleton (Scheme 1) and employs an intramolecular S(N)2 displacement to form the oxetane ring (Schemes 9, 10, 13). The route described could easily be adapted to incorporate additional functionality, making it potentially useful in a total synthesis of dictyoxetane.

  • Lipase-Induced Oxidative Furan Rearrangements
    作者:Jan Deska、Fabian Blume、Petra Sprengart
    DOI:10.1055/s-0036-1591889
    日期:2018.6
    Lipase B from Candida antarctica catalyzes the oxidative ring expansion of furfuryl alcohols using aqueous hydrogen peroxide to yield functionalized pyranones under mild conditions. The method further allows for the preparation of corresponding piperidinone derivatives by enzymatic rearrangement of N-protected furfurylamines.

  • Selective Functionalization of Achmatowicz Rearrangement Products by Reactions with Potassium Organotrifluoroborates under Transition-Metal-Free Conditions
    作者:Silvia Roscales、Víctor Ortega、Aurelio G. Csákÿ
    DOI:10.1021/acs.joc.8b01643
    日期:2018.9.21
    The repertoire of synthetic transformations of the products of the Achmatowicz rearrangement has been expanded by exploring their reactivity with potassium organotrifluoroborates in the absence of transition metals. Depending on the reaction conditions and the substitution pattern of the starting material, the reaction may lead to the stereoselective synthesis of dihydropyranones (2,6-trans), tetrahydropyranones
    通过在不存在过渡金属的情况下探索其与有机三氟硼酸钾的反应性,扩大了Achmatowicz重排产物的合成转化的范围。根据反应条件和原料的取代方式,反应可能会导致立体选择性合成二氢吡喃酮(2,6-反式),四氢吡喃酮(2,3-顺式-2,6-顺式)或官能化的1, 4-二羰基化合物。该方法还适用于一锅合成官能化吡咯。

  • A novel, environment-friendly method to prepare pyranones from furfural alcohols <i>via</i> photocatalytic O<sub>2</sub> oxidation in an aqueous phase

    This study developed a novel photocatalytic method to synthesize pyranones from furfural alcohols. By using 0.2 mol% equivalent of tris-Ir(ppy)3 as a photocatalyst under visible light and O2 as the reaction atmosphere, furfural alcohols were rapidly oxidized and hydrolyzed in the aqueous reaction solution to produce diol intermediates, which further underwent hydrolysis, furan ring-opening and rearrangement
    本研究开发了一种新的光催化方法从糠醛醇合成吡喃酮。在可见光下,以0.2 mol%当量的tris-Ir(ppy) 3作为光催化剂,O 2作为反应气氛,糠醇在反应水溶液中快速氧化水解生成二醇中间体,二醇中间体进一步水解,呋喃开环重排形成最终产物吡喃酮。整个反应在室温下进行,收率高达86%,转化效率高达90%。该方法具有通用性,适用于 5- 和 α-OH 位点上具有不同取代基的糠醛醇。我们原地使用IR 和实时 NMR 检查反应动力学,GC-MS 和同位素标记实验跟踪反应中原子转移的来源,EPR 识别单线态氧。结果表明,该反应遵循一级速率方程,O 2氧化是决速步骤。转移的H 原子来自H 2 O 溶剂,O 原子来自O 2气氛,单线态氧来自O 2光催化。紫外-可见和循环伏安法结果表明,该光催化反应涉及单电子转换过程。我们还使用 DFT 计算来模拟反应路线,并表明 tris-Ir(ppy) 3光催化 O
