制备方法与用途

制备

将亚硝酸钠（20克，288毫摩尔）在40毫升水中制成的溶液滴加到3-氨基-4-硝基吡啶（40克，288毫摩尔）与140毫升34%氟硼酸搅拌混合物中。滴加过程中保持温度在-8℃至-2℃之间。滴加后0.5小时，过滤反应液，并用34%氟硼酸（35毫升）、乙醚（80毫升）洗涤固体产物，在室温下使用高真空干燥12小时。干燥后的固体加热至120℃分解。分解后，将剩余的油状物用80毫升10%碳酸氢钠溶液处理，并用二氯甲烷萃取。合并的萃取液经硫酸钠干燥、过滤并在减压下除去溶剂，得到标题化合物，为浅黄色固体。

  copper-catalyzed reaction of nitroarenes with aryl boronic acids to form diarylamines that uses phenyl silane as the stoichiometric terminal reductant is described. This cross-coupling reaction requires as little as 2 mol % of CuX and 4 mol % of diphosphine for success and tolerates a broad range of functional groups on either the nitroarene or the aryl boronic acid to afford the amine in good yield.

• Lead identification and structure–activity relationships of heteroarylpyrazole arylsulfonamides as allosteric CC-chemokine receptor 4 (CCR4) antagonists
  作者：Afjal H. Miah、Royston C. B. Copley、Daniel O'Flynn、Jonathan M. Percy、Panayiotis A. Procopiou

  DOI：10.1039/c3ob42443j

  日期：——

  A knowledge-based library of aryl 2,3-dichlorophenylsulfonamides was synthesised and screened as human CCR4 antagonists, in order to identify a suitable hit for the start of a lead-optimisation programme. X-ray diffraction studies were used to identify the pyrazole ring as a moiety that could bring about intramolecular hydrogen bonding with the sulfonamide NH and provide a clip or orthogonal conformation that was believed to be the preferred active conformation. Replacement of the core phenyl ring with a pyridine, and replacement of the 2,3-dichlorobenzenesulfonamide with 5-chlorothiophenesulfonamide provided compound 33 which has excellent physicochemical properties and represents a good starting point for a lead optimisation programme. Electronic structure calculations indicated that the preference for the clip or orthogonal conformation found in the small molecule crystal structures of 7 and 14 was in agreement with the order of potency in the biological assay.

  基于知识的芳基2,3-二氯苯磺酰胺类化合物库被合成并筛选为人CCR4拮抗剂，旨在确定一个适合作为先导优化计划起点的候选化合物。X射线衍射研究用于鉴定吡唑环为一个可以通过分子内氢键与磺酰胺NH结合并提供被认为是优选活性构象的夹子或正交构象的基团。用吡啶替换核心苯环，并用5-氯噻吩磺酰胺替换2,3-二氯苯磺酰胺得到了化合物33，其具有优异的物化性质，并代表了一个良好的先导优化计划起点。电子结构计算表明，小分子晶体结构中发现的夹子或正交构象的偏好与生物测定中的效力顺序一致。
