  The regulation of coordination configurations of single-atom sites is highly desirable to boost the catalytic performances of SA catalysts. Here, we demonstrate a versatile complexation-deposition strategy for the synthesis of 13 kinds of dual-metal SA site pairs with uniform and exclusive coordination configurations. The preparation is specifically exemplified by the fabrication of Cu and Co single-atom

  非常需要调节单原子位点的配位构型以提高SA催化剂的催化性能。在这里，我们展示了一种通用的络合沉积策略，用于合成 13 种具有统一和排他配位配置的双金属 SA 位点对。通过蚀刻和热解预合成的金属-有机框架模板，制备 Cu 和 Co 单原子对以及 N 和 P 杂原子共存，具体说明了该制备方法。系统表征揭示了 CuN 4 / CoN 3 P 1和 CuN 4 / CoN 2 P 2中 Cu 和 Co SA 位点的均匀且排他性配位构型，电子在其上不对称分布。令人印象深刻的是，与 CuN 4 / CoN 3 P 1和 CuN 4 / CoN 4对应物相比，CuN 4 / CoN 2 P 2位点对在多种天然类黄酮的合成中表现出显着增强的催化活性和选择性。理论计算结果表明，CuN 4 / CoN 2 P 2上的不对称电子分布位点可以通过降低关键中间体生成的能垒来促进氧分子的吸附和解离，从而在动力学上加速氧化偶联反应过程。

  the iodonium-triiodide ion couple formed through iodine and PEG-400 complexation. The triiodide anion not only helps in the abstraction of a proton from the acetophenone but also promotes the cyclization of intermediate chalcone to the corresponding flavones. The flavones were obtained in very high yields without using any toxic metal catalysts or harsh reaction conditions. The reaction mechanism was

  开发了一种高效的无金属单步方案，用于从 2-羟基苯乙酮和取代苯甲醛直接合成黄酮。这种化学转化仅由碘和 PEG-400 络合形成的碘鎓-三碘化物离子对促进。三碘化物阴离子不仅有助于从苯乙酮中夺取质子，而且促进中间体查耳酮环化为相应的黄酮。在不使用任何有毒金属催化剂或苛刻的反应条件的情况下，以非常高的产率获得了黄酮。通过一系列测试反应和反应中间体的包埋建立了反应机理。开发的方案可以在较温和的反应条件下以高产率直接获取黄酮，并具有良好的底物兼容性，包括羟基化衍生物。

  Central neuromedin U 2 receptor (NMU2R) plays important roles in the regulation of food intake and body weight. Identification of NMU2R agonists may lead to the development of pharmaceutical agents to treat obesity. Based on the structure of rutin, a typical flavonoid and one of the NMU2R agonists we previously identified from an in-house made natural product library, 30 flavonoid derivatives have been synthesized and screened on a cell-based reporter gene assay. A number of compounds were found to be selective and highly potent to NMU2R. For example, the EC50 value of compound NRA 4 is very close to that of NMU, the endogenous peptide ligand of NMU2R. Structure-activity relationship analysis revealed that a 3-hydroxyl group in ring C and a 2'-fluoride group in ring B were essential for this class of compounds to be active against NMU2R.
