  been made of the reaction of aryl oxygen compounds with elemental fluorine in hydrogen fluoride and acetonitrile. Hydrogen fluoride acted as a good solvent in the reaction of salicylic acid, salicylaldehyde and phenyl salicylate. Salicylalcohol gave a mixture of fluorination and oxidation products. Diphenyl derivatives were also fluorinated and gave mainly monofluoro compounds.

  As a part of our systematic study of antimycobacterially active derivatives of salicylamides, a series of nineteen derivatives of N-(2-pyridylmethyl)salicylamides and N-(3-pyridylmethyl)salicylamides was synthesised. The compounds exhibited in vitro activity against Mycobacterium tuberculosis and M. avium. Their lipophilicity, R M, was measured by thin layer chromatography on silica gel impregnated with trioctadecylsilane and the logarithm of the partition coefficient (octanol-water), logP, was calculated. Both the parameters of lipophilicity correlated. The quantitative relationship between the structure and antimycobacterial activity was calculated. Antimycobacterial activity increased with an increase in lipophilicity. The N-(2-pyridylmethyl)salicylamide derivatives were more active than the derivatives of isomeric N-(3-pyridylmethyl)salicylamides. The geometry of compounds was calculated and the calculation was verified by measuring the length of the hydrogen bond between hydroxyl and carbonyl groups on the salicylic moiety.

  摘要：作为我们系统研究水杨酰胺类抗结核活性衍生物的一部分，合成了一系列19个N-(2-吡啶甲基)水杨酰胺和N-(3-吡啶甲基)水杨酰胺衍生物。这些化合物在体外显示出对结核分枝杆菌和分枝杆菌的活性。通过在三十八烷基硅烷浸渍的硅胶上进行薄层色谱测量它们的亲脂性R M，并计算了分配系数（辛醇-水）的对数值logP。两个亲脂性参数相关。计算了结构与抗结核活性之间的定量关系。随着亲脂性的增加，抗结核活性增强。N-(2-吡啶甲基)水杨酰胺衍生物比同分异构体N-(3-吡啶甲基)水杨酰胺衍生物更活跃。计算了化合物的几何结构，并通过测量水杨酸基团上羟基和羰基之间氢键的长度来验证计算结果。

  The series of derivatives of substituted N-pyridinylsalicylamides were synthesized. The compounds were evaluated for in vitro antimycobacterial activity against Mycobacterium avium and two strains of Mycobacterium kansasii. In the quantitative structure activity relationships analysis (QSAR), the Free-Wilson and Hansch approaches were used but the analysis was not significant. (The standard deviations

  合成了一系列取代的N-吡啶基水杨酰胺衍生物。评价化合物对鸟分枝杆菌和堪萨斯分枝杆菌的两种菌株的体外抗分枝杆菌活性。在定量结构活性关系分析（QSAR）中，使用了Free-Wilson和Hansch方法，但该分析并不重要。（回归系数的标准偏差大于系数的值）。分子被分离为分子中的杂环和水杨基部分，并且还研究了取代基对水杨基部分的影响。5-氯吡啶-2-基以及水杨基部分被4或5位上的氯取代对分枝杆菌活性增加的影响最大。

  The Ni-catalyzed C−O/O−H annulation of salicylate esters with alkynes, leading to the production of chromone derivatives is reported. The key step in the reaction is the cleavage of an acyl C-O bond. The presence of a base is essential for the reaction to proceed.

  Herein, we report a catalytic radical-Smiles rearrangement system of arene migration from ether to carboxylic acid with riboflavin tetraacetate (RFT), a readily available ester of natural vitamin B2, as the photocatalyst and water as a green solvent, being free of external oxidant, base, metal, inert gas protection, and lengthy reaction time. Not only the known substituted 2-phenyloxybenzoic acids

  在此，我们报道了一种芳烃从乙醚迁移到羧酸的催化自由基-Smiles重排系统，以核黄素四乙酸酯（RFT）（一种容易获得的天然维生素B2酯）为光催化剂，以水为绿色溶剂，不含外部氧化剂、碱、金属、惰性气体保护、反应时间长。不仅是已知的取代的2-苯氧基苯甲酸底物，而且一组基于萘和杂环的类似物首次被转化为相应的芳基水杨酸酯。机理研究，特别是一些动力学同位素效应（KIE）实验，表明双功能黄素光催化剂能够实现连续的电子转移-质子转移过程。
