  在无过渡金属条件下过硫酸钠促进的单硝基芳基胺的位点选择性合成

  摘要：

  本文公开了由保护的芳基胺实际制备硝基芳基胺的方法。在该系统中，在过硫酸钠存在下没有任何过渡金属催化剂的情况下，亚硝酸钠用作硝化试剂。这种有效的位点选择方案是通过自由基途径在室温下短时间发生的。

  Rh(III)-Catalyzed Cascade Oxidative Olefination/Cyclization of Picolinamides and Alkenes via C–H Activation

  摘要：

  Rh(III)-catalyzed cascade oxidative alkenylation/cyclization of picolinamides and alkenes to furnish pyrido pyrrolone derivatives is described, in which three C-H bonds and one N-H bond broke, while one C-C bond and one C-N bond formed. The reaction proceeded with high yield and high regioselectivity and stereoselectivity. Moreover, copper acetate can also be used in catalytic amounts with O-2 serving as the terminal oxidant.

  amenable for late-stage functionalization of natural compounds and biologically relevant motifs, allowing a straightforward synthesis of a large library of CF3-containing enamides, the high-value pharmacophores, in a single step from readily accessible amides, Langlois’ reagent, and alkynes. The current methodology can also be successfully extended to difluoromethylamidation of alkynes. Additionally

  炔烃的自由基 1,2-双官能化反应已发展成为制备多取代亚烷基的通用方法。然而，尽管生成的烯胺在天然分子、生物活性和药物化合物中普遍存在，但仍缺乏进行碳胺化的强有力的催化策略。在此，我们表明，明智地安装在胺上的二齿配位基团可以作为实现炔烃自由基三氟甲基酰胺化的有效工具。该策略表现出广泛的底物范围和良好的官能团兼容性，适合天然化合物和生物学相关基序的后期功能化，从而可以直接合成大型 CF 3文库含有烯酰胺的高价值药效团，只需一步即可从易于获得的酰胺、朗格卢瓦试剂和炔烃中获得。目前的方法还可以成功扩展到炔烃的二氟甲基酰胺化。此外，还进行了各种机理实验，如竞争实验、H/D同位素交换实验、自由基陷阱实验、哈米特研究和动力学研究，以更好地理解反应机理。
• Cobalt Complexes Appended with <i>para</i>- and <i>meta</i>-Arylcarboxylic Acids: Influence of Cation, Solvent, and Symmetry on Hydrogen-Bonded Assemblies

  The present work shows the syntheses, structures, and hydrogen-bonding-based self-assembly of Co3+ coordination complexes containing appended arylcarboxylic acid groups. The carboxylic acid groups are present at either the para or the meta position of the appended arene ring. Every Co3+ coordination complex offers both hydrogen-bond donors (in O-H groups of atylcarboxylic acid) and acceptors (in C=O-amide groups as well as C=O-acid of arylcarboxylic acid) in a single molecule. As a consequence, all molecules self-assemble in a highly complementary and unique structural fashion via an array of inter- and intramolecular hydrogen bonding. The position of carboxylic acid, presence of cation, type of cation, and solvent of crystallization has significantly affected/altered the self-assembly process of complementary functional groups.

  A practical preparation of nitroarylamines from protected arylamines was herein disclosed. In this system, sodium nitrite acted as a nitration reagent in the presence of sodium persulfate without any transition-metal catalysts. This efficient site-selective protocol took place at room temperature for a short time through a free radical pathway.
