  通过氮杂芳烃的净光化学碳缺失进行支架跳跃

  摘要：

  发现化学家通常通过迭代结构优化方法来识别特定目的的分子，但化合物系列中每个连续候选分子的制备很少能够以与其思维过程相匹配的方式进行。这是因为以简单的方式修改化合物核心所需的许多必要的化学转化并不适用于复杂的环境。我们报告了一种方法，通过允许化学家直接在化学上不同的杂芳族支架之间跳跃来解决这个问题的一个方面。具体来说，我们表明用 390 纳米光选择性光解喹啉 N-氧化物，然后进行酸促进重排，得到 N-酰基吲哚，同时显示出与医学相关功能的广泛相容性。演示了对具有药学意义的化合物的后期骨架修饰以及涉及连续单原子变化的更复杂转化的应用。

• Experimental and QSAR Studies on Antimicrobial Activity of Benzimidazole Derivatives
  作者：Ayarivan Puratchikody、Govindasamy Nagalakshmi、Mukesh Doble

  DOI：10.1248/cpb.56.273

  日期：——

  Twenty eight analogues of benzimidazoles had been synthesized and tested for their antimicrobial activity against four bacteria (Staphylococcus auerus, Escherichia coli, Bacillus pumilus and Proteus vulgaris) and two fungi (Aspergillus flavus and Aspergilus niger). Compounds with R as C6H4NO2 and R′ as SO2C6H4–CH3(p), with R as C6H4OCH3 and R′ as SO2C6H4–CH3(p), and with R as CH2C6H5 and R′ as CH2(CH2)9Cl exhibited comparable or higher antibacterial activity than Ciprofloxacin against S. auerus and E. coli and, higher activity than Nystatin against A. flavus. Several other compounds showed better activity than the standard antibiotic for E. coli. Compounds with R as CCl3 and R′ as SO2C6H4–CH3(p) or COC6H5 exhibited the lowest activity against all the organisms. Addition of methylene groups in the R′ position increased activity. Many of the compounds showed better activity than Ciprofloxacin for one or more organisms. Compound with R as CH2OC6H5 and R′ as CH2(CH2)9Cl exhibited higher activity against both the fungii than the control Nystatin. Quantitative structure activity relationships (QSARs) developed were good for all the organisms (R2=0.65 to 0.88; Radj2 = 0.63 to 0.86) and the predictive capability of the developed models was also reasonable (q2=0.52 to 0.83). The models had two to three independent variables. The data for the models which had three independent variables were divided into training and test/validation sets. The former set was used to develop the QSAR and these developed models were used to predict the activity of the test set data. In all the three cases the predictive capability of the models was good. The molecular descriptors identified were predominantly log P, electronic parameters, molecular size, shape and area. A positive correlation existed between the antibacterial activity and the first principal component.

  已经合成了28种苯并咪唑类衍生物，并对它们对四种细菌（金黄色葡萄球菌、大肠杆菌、短小芽孢杆菌和普通变形杆菌）和两种真菌（黄曲霉和黑曲霉）的抗微生物活性进行了测试。当R为C6H4NO2、R′为SO2C6H4-CH3(p)，R为C6H4O 、R′为SO2C6H4- (p)，以及R为 C6H5、R′为CH2( )9Cl时，这些化合物的抗菌活性与环丙沙星相当或更高，对金黄色葡萄球菌和大肠杆菌的活性高于制霉菌素对黄曲霉的活性。还有几种化合物对大肠杆菌的活性优于标准抗生素。R为CCl3、R′为SO2C6H4- (p)或COC6H5的化合物对所有生物体的活性最低。在R′位置添加亚甲基基团可以提高活性。许多化合物对一种或多种生物体的活性优于环丙沙星。R为 OC6H5、R′为 ( )9Cl的化合物对这两种真菌的活性高于对照制霉菌素。开发的定量结构-活性关系（QSARs）对所有生物体都很好（R2=0.65至0.88；Radj2 = 0.63至0.86），开发模型的预测能力也合理（q2=0.52至0.83）。这些模型包含两到三个独立变量。具有三个独立变量的模型的数据被分为训练集和测试/验证集。前者用于开发QSAR，这些开发的模型用于预测测试集数据的活性。在所有三种情况下，模型的预测能力都很好。识别的分子描述符主要是log P、电子参数、分子大小、形状和面积。抗菌活性与第一主成分之间存在正相关关系。

  practical intramolecular C–H amidation methodology has been developed using molecular iodine under basic conditions. The required imine substrates were readily obtained by condensation of simple o-phenylenediamine derivatives and aldehydes. The transition-metal-free cyclization reaction described here works well with crude imines and allows for the sequential synthesis of N-protected benzimidazoles

  在基本条件下，使用分子碘已开发出一种实用的分子内C–H酰胺化方法。通过简单的邻苯二胺衍生物和醛的缩合可以容易地获得所需的亚胺底物。本文所述的无过渡金属的环化反应可与粗亚胺很好地配合，无需分离较不稳定的缩合中间体，即可连续合成N-保护的苯并咪唑。这种操作简单的合成方法广泛适用于各种芳族，脂肪族和肉桂醛，以有效和可扩展的方式生产各种1,2-二取代的苯并咪唑衍生物。
• Metal-free cross-dehydrogenative coupling of benzimidazoles with aldehydes to N-acylbenzimidazoles
  作者：Lin Yu、Min Wang、Lei Wang

  DOI：10.1016/j.tet.2014.07.009

  日期：2014.9

  A novel and direct cross-dehydrogenative coupling (CDC) between benzimidazoles with aldehydes promoted by di-tert-butyl peroxide (DTBP) was developed. The reactions generated the corresponding N-acylbenzimidazoles in good yields under metal-free conditions. This method has broad substrate scope and high efficiency. (C) 2014 Elsevier Ltd.
