  Copper(II)-catalyzed oxidation of 4-carboxythiazolines and 4-carboxyoxazolines to 4-carboxythiazoles and 4-carboxyoxazoles

  摘要：

  A mild copper(II)-catalyzed oxidation of 4-carboxythiazolines and 4-carboxyoxazolines to 4-carboxythiazoles and 4-carboxyoxazoles has been developed. Various substrates with alkyl or aryl substitutions at 2-position on azoline ring could be smoothly oxidized to the desired products in good to excellent yields. Moreover, the hydrolysis of the ester group could be avoided under this method. (C) 2011 Elsevier Ltd. All rights reserved.

  Herein, we report a one‐electron strategy for catalytic amide synthesis that enables the direct carbamoylation of (hetero)aryl bromides. This radical cross‐coupling approach, which is based on the combination of nickel and photoredox catalysis, proceeds at ambient temperature and uses readily available dihydropyridines as precursors of carbamoyl radicals. The method's mild reaction conditions make

  在本文中，我们报告了一种催化酰胺合成的单电子策略，该策略可实现（杂）芳基溴化物的直接氨基甲酰基化。这种自由基交叉偶联方法基于镍和光氧化还原催化的结合，在环境温度下进行，并使用现成的二氢吡啶作为氨基甲酰基自由基的前体。该方法温和的反应条件使其能够耐受敏感的官能团底物，并允许在生物学相关的杂环中安装酰胺支架。此外，我们安装了带有电子贫乏和空间受阻胺部分的酰胺官能团，而这是用传统的脱水缩合方法难以制备的。

  heptafluoroisopropoxylation reactions through the invention of a series of redox-active N-OCF(CF3)2 reagents. These reagents were readily prepared from the oxidative heptafluoroisopropylation of hydroxylamines with AgCF(CF3)2. The substitutions on the nitrogen atom significantly affected the properties and reactivities of N-OCF(CF3)2 reagents. Accordingly, two types of N-OCF(CF3)2 reagents including N-OCF(CF3)2

  七氟异丙基 (CF(CF 3 ) 2 ) 在药物和农用化学品中很普遍。然而，七氟异丙氧基化(OCF(CF 3 ) 2 ) 化合物在很大程度上仍未得到充分探索，这可能是由于缺乏对这些化合物的有效获取。在此，我们通过一系列具有氧化还原活性的N -OCF(CF 3 ) 2试剂的发明，公开了实用且高效的七氟异丙氧基化反应。这些试剂很容易通过羟胺与 AgCF(CF 3 ) 2的氧化七氟异丙基化反应制备. 氮原子上的取代显着影响了N -OCF(CF 3 ) 2试剂的性质和反应性。因此，两种类型的N -OCF(CF 3 ) 2试剂包括N -OCF(CF 3 ) 2邻苯二甲酰亚胺A和N -OCF(CF 3 ) 2苯并三唑鎓盐O'用作OCF(CF 3 ) 2分别为阴离子和自由基前体。该协议能够对一系列底物进行直接七氟异丙氧基化，以中等至优异的产量提供相应的产品。
