  Synthesis and biological evaluation of new N-acyl-homoserine-lactone analogues, based on triazole and tetrazole scaffolds, acting as LuxR-dependent quorum sensing modulators

  摘要：

  New analogues of N-acyl-homoserine-lactone (AHL), in which the amide was replaced by a triazole or tetrazole ring, were prepared and tested for their activity as LuxR-dependent QS modulators. Several compounds showed a level of antagonistic or agonistic activity, notably some 1,4-triazolic and 1,5-tetrazolic derivatives, whereas the 2,5-tetrazolic compounds were inactive. In 1,5-tetrazoles, substituted with butyrolactone and an alkyl chain, the activity was reversed, depending on the connection between the lactone and the tetrazole. The C-N connected compounds were agonists whereas the C-C connected ones were antagonists. (C) 2012 Elsevier Ltd. All rights reserved.

  吡啶基-三唑配体体系，用于高效CuI催化的叠氮化物-炔烃环加成反应

  摘要：

  吡啶基-三唑配体系统（包括N 2 -2-吡啶基1,2,3-三唑和N 1 / N 2取代的2-（NH（1,2,3-三唑-4-基）吡啶被发现是CuI催化的叠氮化物-炔烃环加成（CuAAC）反应的优良配体。催化剂负载量低，反应时间短，催化剂易于回收利用，环境温度和开瓶条件使该催化系统非常实用。碘化物阴离子可形成碘桥，与这些配体一起构建稳定的双核Cu（I）配合物，这是实现高催化活性的关键。虽然CuBr和CuCl不适合该配体系统，因为Br和Cl原子的尺寸不合适，无法形成相应的双核Cu（I）配合物。

  new magnetic heterogeneous copper catalyst was prepared by immobilization of copper ions onto a cross-linked polymeric nanocomposite composed of starch grafted polyacrylamide and functionalized Fe3O4 magnetic nanoparticles. The resulting support was loaded with large amounts of copper ions (1.6 mmol g−1). The prepared catalyst is highly active in Huisgen 1,3-dipolar cycloaddition reactions of different

  通过将铜离子固定在由淀粉接枝的聚丙烯酰胺和功能化的Fe 3 O 4磁性纳米粒子组成的交联聚合物纳米复合材料上，制备了一种新型的磁性异质铜催化剂。所得的载体上载有大量的铜离子（1.6mmol g -1）。所制备的催化剂在低催化剂量下对不同叠氮化物和炔烃的Huisgen 1,3-偶极环加成反应具有很高的活性。在温和的条件下以高收率生产了各种相应的1,2,3-三唑。该催化剂易于回收并再用于十个反应循环，没有观察到明显的催化活性损失。

  new approach exploiting the dual properties of thiol‐grafted cellulose paper for promoting copper‐catalyzed [3+2]‐cycloadditions of organic azides with alkynes and adsorbing residual copper species in solution was developed. The thiol‐grafted cellulose paper, used as a paper strip, effects the reduction of CuII to catalytically active CuI and acts as a powerful adsorbent for copper, thereby facilitating

  An efficient copper-catalyzed three-component tandem reaction of alkynes, α-diazo esters, and TMSN3 to construct triazoles has been developed. Through this strategy, a number of diverse N-substituted 1,2,3-triazoles were conveniently obtained in moderate to good yields from simple and readily available starting materials using K2CO3 as the base.
