  • Catalyst- and additive-free Baeyer–Villiger-type oxidation of α-iodocyclopentenones to α-pyrones: using air as the oxidant
    作者:Yuanyuan Zhou、Xianxiao Chen、Xiangxiang Ling、Weidong Rao
    DOI:10.1039/c9gc02725d
    日期:——
    approach for the synthesis of α-pyrones via Baeyer–Villiger-type oxidation of α-iodocyclopentenones through a catalyst- and additive-free system using air as an environmentally benign oxidant is described. The reaction exhibits excellent functional group compatibility and provides a simple and efficient protocol for the construction of highly functionalized α-pyrones under mild reaction conditions.
    描述了一种有效的合成方法,该方法通过使用空气作为环境良性氧化剂的无催化剂和无添加剂系统,通过α-碘代环戊烯的Baeyer-Villiger型氧化来合成α-吡喃酮。该反应显示出优异的官能团相容性,并为在温和的反应条件下构建高度官能化的α-吡喃酮提供了简单有效的方案。
  • RhCl(PPh3)3/DPPF: A Useful and Efficient Catalyst for Cross-Coupling Reactions of Activated Alkenyl Tosylates with Arylboronic Acids

    Suzuki–Miyaura cross-coupling of activated alkenyl tosylates is described. The results not only represent the first examples of the rhodium-catalyzed Suzuki–Miyaura coupling of activated alkenyl tosylates with arylboronic acids under mild conditions, but also provide an efficient route for the synthesis of some natural product-like compounds, such as furan-2(5H)-one, coumarin, pyrone, and quinolin-2(1H)-one

    Tripalladium clusters of the type [Pd3(PPh3)4]2+, wherein three linearly connected Pd atoms are stabilized by phosphine and arsine ligands, have been detected and isolated as intermediates during the reduction of well-defined mononuclear [Pd(OTf)2(XPh3)2] (X = P and X = As, respectively) to Pd nanoparticles (PdNPs). The isolated [Pd3(PPh3)4]2+ cluster isomerizes on broad-band UV irradiation to form

  • Environmentally Sustainable and Chemo-selectively Favorable Synthesis of Substituted 2<i>H</i>-Pyran-2-ones in Water under MWI
    作者:Liang-Yan Cui、Xin Wang、Yan He、Xue-Sen Fan
    DOI:10.1002/jccs.201300013
    日期:2014.2
    this paper, a novel synthesis of diversely substituted 2H‐pyran‐2‐ones via the tandem reaction of 3‐hydroxyhexa‐4,5‐allenic esters in water under the promotion of MWI has been developed. Compared with those reactions carried out in organic solvents, water mediated synthesis of poly‐substituted 2H‐pyran‐2‐ones is not only environmentally sustainable, but also chemo‐selectively favorable.
