  使内环化再次变得有利：通过叠氮化物基团对2-叠氮基芳基溴化物进行锂化/环化的概念上新的苯并三唑合成方法

  摘要：

  尽管苯并三唑是重要的且无处不在，但目前仅有一种概念上的合成方法：将两个邻氨基与亲电氮原子桥连。在此，我们公开了新的可行的选择-将内获得2 azidoaryl lithiums -cyclization原位从2 azidoaryl溴化物。使用二十四个带有各种烷基，烷氧基，全氟烷基和卤素取代基的实例来说明反应的范围。我们发现叠氮化物基团的导向作用允许在含有几个溴原子的芳基叠氮化物中进行选择性的金属-卤素交换。此外，（2-溴苯基）重氮甲烷经历类似的环化以生成吲唑。因此，芳基锂的环化包含邻-X = Y = Z基团是合成芳族杂环的一种新的通用方法。DFT计算表明，观察到的内选择性适用于经历“ 1,1-加成”（即叠氮化物，重氮化合物和异腈）的其他官能团的阴离子环化反应。与此相反，与遵循“1,2-加成”图案（氰酸酯，硫氰酸酯，异氰酸酯，异硫氰酸酯，和腈）的杂原子官能团的环化反应倾向于外-cyclizat

  日期：2001.4.1

  Planar N-aromatic maleimides were found to have a low relative excited-state triplet yield, showing significant shift of the primary maleimide UV absorption band with changes in solvent polarity, and did not initiate free radial polymerization upon direct UV excitation. Twisted N-aromatic maleimides have a higher relative triplet yield, show negligible shift of the primary maleimide UV absorption band

  使用丙烯酸酯单体与各种 N-芳族马来酰亚胺组合制备可光聚合组合物。N-芳族马来酰亚胺分为两组：可以采用平面构象的组和不能采用平面构象的组。使用单晶 X 射线衍射光谱、激光闪光光解光谱、紫外-可见吸收光谱和光差扫描量热法对马来酰亚胺进行了表征。发现平面 N-芳族马来酰亚胺具有较低的相对激发态三重态产率，显示初级马来酰亚胺 UV 吸收带随溶剂极性的变化而显着偏移，并且在直接 UV 激发时不会引发自由基聚合。Twisted N-aromatic maleimides 具有较高的相对三重态产率，显示初级马来酰亚胺紫外吸收带的可忽略的偏移，具有溶剂极性，并在直接激发时引发自由基聚合。发现添加二苯甲酮会显着...

  disclosed that the known IKK-β inhibitor IMD-0354 potently suppresses colistin resistance in several Gram-negative strains. In this study, we explore the structure-activity relationship (SAR) between the IMD-0354 scaffold and colistin resistance suppression, and identify several compounds with more potent activity than the parent against highly colistin-resistant strains of Acinetobacter baumannii and Klebsiella

  由多重耐药（MDR）细菌，特别是革兰氏阴性菌引起的感染是一个不断升级的全球健康威胁。临床医生常常被迫使用最后手段抗生素粘菌素。然而，粘菌素耐药性正变得越来越普遍，导致可能出现多重耐药革兰氏阴性菌感染没有治疗选择的情况。开发规避细菌耐药机制的佐剂是开发新抗生素的一种有前途的正交方法。我们最近披露，已知的 IKK-β 抑制剂 IMD-0354 可有效抑制几种革兰氏阴性菌株的粘菌素耐药性。在这项研究中，我们探索了 IMD-0354 支架与粘菌素耐药性抑制之间的构效关系 (SAR)，并鉴定了几种比母体对鲍曼不动杆菌和肺炎克雷伯菌高度粘菌素耐药菌株具有更有效活性的化合物。

  in aryl azides containing several bromine atoms. Furthermore, (2-bromophenyl)diazomethane undergoes similar cyclization to give an indazole. Thus, cyclizations of aryl lithiums containing an ortho–X = Y = Z group emerge as a new general approach for the synthesis of aromatic heterocycles. DFT computations suggested that the observed endo-selectivity applies to the anionic cyclizations of other functionalities
