  摘要：

  在本文中，我们描述了通过C-O键的活化，铁催化的烯基和芳基氨基甲酸酯的硼酸酯化反应。该方案显示出高效率，广泛的底物范围以及生物相关化合物的后期硼化，因此在药物化学中提供了潜在的应用。而且，该方法能够使酚衍生物进行正交转化，并且还为合成多取代的芳烃提供了良好的机会。初步的机理研究表明，通过自由基途径的Fe II / Fe III催化循环可能与反应有关。

  photocatalytic borylation method that can effect borylation of a wide range of substrates, including strong C‒O bonds, remains elusive. Herein, we report a general, metal-free visible light-induced photocatalytic borylation platform that enables borylation of electron rich derivatives of phenols and anilines, chloroarenes, as well as other haloarenes. The reac-tion exhibits excellent functional group

  硼酸是中心重要的功能基序和合成前体。可见光诱导的硼酸化可以提供结构多样化的硼酸盐，但一种广泛有效的光催化硼酸化方法可以影响包括强 C-O 键在内的多种底物的硼化，仍然难以实现。在此，我们报告了一种通用的、无金属的可见光诱导光催化硼化平台，该平台能够对苯酚和苯胺、氯芳烃以及其他卤代芳烃的富电子衍生物进行硼化。该反应表现出优异的官能团耐受性，正如一系列结构复杂底物的硼化反应所证明的那样。值得注意的是，该反应是由吩噻嗪催化的，这是一种简单的有机光催化剂，MW< 200通过质子耦合电子转移机制介导了以前无法实现的可见光诱导的苯酚衍生物单电子还原，还原电位为~-3 V vs SCE。机理研究指出了光催化剂-碱相互作用的关键作用。

  In an effort to identify novel anti-inflammatory compounds, a series of flavone derivatives were synthesized and biologically evaluated for their inhibitory effects on the production of nitric oxide (NO) and prostaglandin E2 (PGE2), representative pro-inflammatory mediators, in LPS-induced RAW 264.7 cells. Their structure-activity relationship was also investigated. In particular, we found that compound

  Metal-organic framework (MOFs) compositions based on nitrogen donor-based organic bridging ligands, including ligands based on 1,3-diketimine (NacNac), bipyridines and salicylaldimine, were synthesized and then post-synthetically metalated with metal precursors, such as complexes of first row transition metals. Metal complexes of the organic bridging ligands could also be directly incorporated into the MOFs. The MOFs provide a versatile family of recyclable and reusable single-site solid catalysts for catalyzing a variety of asymmetric organic transformations. The solid catalysts can also be integrated into a flow reactor or a supercritical fluid reactor.
