  Synthesis and biological evaluation of 5-substituted and 4,5-disubstituted-2-arylamino oxazole TRPV1 antagonists

  摘要：

  The synthesis and structure-activity relationships of a series of 5-monosubstituted and 4,5-disubstituted 2-arylaminooxazoles as novel antagonists of the transient receptor potential vanilloid 1 (TRPV1) receptor are described. The 7-hydroxy group of the tetrahydronaphthyl moiety on the 2-amino substituent of the oxazole ring was important for obtaining excellent in vitro potency at the human TRPV1 receptor, while a variety of alkyl and phenyl substituents at the 4- and 5-positions of the oxazole ring were well tolerated and yielded potent TRPV1 antagonists. Despite excellent in vitro potency, the 5-monosubstituted compounds suffered from poor pharmacokinetics. It was found that 4,5-disubstitution on the oxazole ring was critical to the improvement of the overall pharmacokinetic profile of these analogues, which led to the discovery of compound (R)-27, a novel TRPV1 antagonist with good oral activity in preclinical animal models of pain.

  镍催化直接C ？有机硅试剂对杂芳烃的氢化和烯基化作用

  摘要：

  打破沉默：在镍催化剂的存在下，杂芳烃与芳基或烯基硅烷的直接交叉偶联有效地进行，从而有效地形成了广泛的芳基和烯基-杂芳基键（请参见方案； DMAc = N，N-二甲基乙酰胺，bpy = 2,2'-联吡啶）。这种催化作用代表了在催化CH官能化化学中使用有机硅烷的新途径。

• Copper-Mediated CH/CH Biaryl Coupling of Benzoic Acid Derivatives and 1,3-Azoles
  作者：Mayuko Nishino、Koji Hirano、Tetsuya Satoh、Masahiro Miura

  DOI：10.1002/anie.201300587

  日期：2013.4.15

  intermolecular direct biaryl coupling of benzoic acid derivatives and 1,3‐azoles has been developed. The key to success is the installation of an amide‐based bidentate coordinating group, which is easily removed and transformed into the parent ester groups after the coupling reaction. Kinetic studies indicate that the rate‐limiting step is the aromatic CH bond cleavage of benzoic acid derivatives.

  热电偶：已开发出一种不含贵金属的铜介导的苯甲酸衍生物和1,3-唑类分子间直接联芳基偶合剂。成功的关键是安装基于酰胺的双齿配位基团，该基团在偶联反应后很容易被除去并转变为母体酯基团。动力学研究表明，限速步骤是苯甲酸衍生物的芳香族CH键裂解。

• Nickel- and Copper-Catalyzed Direct Alkynylation of Azoles and Polyfluoroarenes with Terminal Alkynes under O₂ or Atmospheric Conditions

  The direct C−H alkynylation of azoles with terminal alkynes proceeds efficiently under a nickel/O2 catalytic system. On the other hand, a copper/air catalyst enables the coupling of polyfluoroarenes with terminal alkynes. These catalyses provide new accesses to arylacetylenes through the formal direct Sonogashira coupling.

  日期：2010.4.16

  A highly efficient and versatile Pd-catalyzed direct alkynylation reaction of heterocycles with 1-bromoalkynes was developed. The substrate scope of the reaction was very broad to include not only azoles but also azolines for the first time, thus offering an important advance in the direct functionalization of heterocycles.
