  • An Efficient [2 + 2 + 1] Synthesis of 2,5-Disubstituted Oxazoles via Gold-Catalyzed Intermolecular Alkyne Oxidation
    作者:Weimin He、Chaoqun Li、Liming Zhang
    DOI:10.1021/ja2029188
    日期:2011.6.8
    reaction of gold carbene intermediates generated via gold-catalyzed alkyne oxidation has been realized using nitriles as both the reacting partner and the reaction solvent, offering a generally efficient synthesis of 2,5-disubstituted oxazoles with broad substrate scope. The overall reaction is a [2 + 2 + 1] annulation of a terminal alkyne, a nitrile, and an oxygen atom from an oxidant. The reaction conditions
    通过催化炔氧化生成的卡宾中间体的第一个有效分子间反应已经实现,使用腈作为反应伙伴和反应溶剂,提供了具有广泛底物范围的 2,5-二取代恶唑的普遍有效合成。整个反应是末端炔烃、腈和来自氧化剂的氧原子的 [2 + 2 + 1] 环化。反应条件异常温和,并且容易耐受一系列官能团。对于复杂和/或昂贵的腈,在没有任何溶剂且仅使用 1 mol% BrettPhosAuNTf(2) 作为催化剂的情况下,仅 3 equiv 就足以实现可用的产率。
  • Iron‐Promoted Practical One‐Pot Synthesis of 2,5‐Disubstituted Oxazoles
    作者:Songhui Chen、Donghu Bai、Feng Shi、Jian Li、Chunju Li、Xueshun Jia
    DOI:10.1002/cjoc.201100683
    日期:2012.7
    A practical onepot protocol for the synthesis of 2,5disubstituted oxazoles from 1‐aryl‐2‐nitroethanones was reported. In the presence of iron/AcOH in acetonitrile, the reaction of 1‐aryl‐2‐nitroethanones with trimethyl orthoacetate or trimethyl orthobenzoate delivered the corresponding 2,5disubstituted oxazoles in moderate to good yields.

    日期:2017.5.19
    heterogeneous gold(I)-catalyzed [2 + 2 + 1] annulation of terminal alkynes, nitriles, and oxygen atoms has been achieved by using an MCM-41-immobilized phosphine–gold(I) complex as catalyst and 8-methylquinoline N-oxide as oxidant under mild conditions, yielding a variety of 2,5-disubstituted oxazoles in good to excellent yields with broad substrate scope. The new heterogeneous gold(I) catalyst can
