  Novel selective thiazoleacetic acids as CRTH2 antagonists developed from in silico derived hits. Part 1

  摘要：

  Structure-activity relationships of three related series of 4-phenylthiazol-5-ylacetic acids, derived from two hits emanating from a focused library obtained by in silico screening, have been explored as CRTH2 (chemoattractant receptor-homologous molecule expressed on Th2 cells) antagonists. Several compounds with double digit nanomolar binding affinity and full antagonistic efficacy for human CRTH2 receptor were obtained in all subclasses. The most potent compound was [2-(4-chloro-benzyl)-4-(4-phenoxy-phenyl)-thiazol-5-yl] acetic acid having an binding affinity of 3.7 nM and functional antagonistic effect of 66 nM in a BRET and 12 nM in a cAMP assay with no functional activity for the other PGD2 DP receptor (27 mu M in cAMP).

• Copper-Catalyzed One-Pot Synthesis of Unsymmetrical Arylurea Derivatives via Tandem Reaction of Diaryliodonium Salts with <i>N</i>-Arylcyanamide

  日期：2014.9.5

  efficient “one-pot” approach to multiple substituted ureas from N-arylcyanamide and diaryliodonium salts has been presented. The two-step procedure involved the weak base-promoted chemoselective arylation of secondary amines with diaryliodonium and Cu-catalyzed nucleophilic addition of N-arylcyanamide with second diaryliodonium. The diverse unsymmetrical arylureas were obtained in up to 91% yield for 29 examples

  已经提出了一种有效的“一锅法”，用于从N-芳基氰酰胺和二芳基碘鎓盐中制备多种取代的尿素。该两步过程涉及仲胺与二芳基碘鎓的弱碱促进的化学选择性芳基化和第二仲芳基碘鎓的铜催化的N-芳基氰酰胺的亲核加成。对于29个实施例，以高达91％的收率获得了各种不对称的芳基脲。

  The synthesis of cyanamides and tetrazoles from isothiocyanates through tandem reaction using cobalt catalyst has been demonstrated. In the case of tetrazole preparation, the reaction involved addition/desulfurization/nucleophilic addition/electrocyclization, whereas aromatic cyanamides were constructed from isothiocyanates through addition/desulfurization. Cheap cobalt sulfate was used for the synthesis

  已经证明使用钴催化剂通过串联反应由异硫氰酸酯合成氰酰胺和四唑。在制备四唑的情况下，反应涉及加成/脱硫/亲核加成/电环化，而芳族氰胺是通过加成/脱硫由异硫氰酸酯构成的。廉价的硫酸钴被用于合成各种氰胺和四唑。另外，发现钴催化剂是以前没有报道的脱硫试剂。从起始前体以高产率到高产率获得了最终产物。

  An expansion of methodologies aimed at the formation of versatile organonitriles, via the intramolecular aminocyanation of unactivated alkenes, is herein reported. Importantly, the need for a rigid tether in these reactions has been obviated. The ease-of-synthesis and viability of substrates bearing flexible backbones has permitted for diastereoselective variants as well. We demonstrated the utility

  本文报道了旨在通过未活化烯烃的分子内氨基氰化形成多功能有机腈的方法的扩展。重要的是，在这些反应中不需要刚性系绳。带有柔性主链的底物的合成容易性和生存能力也允许非对映选择性变体。我们通过形成吡咯烷酮、哌啶酮、异吲哚酮和舒尔坦证明了这种方法的实用性。此外，还证明了这些基序随后转化为医学相关分子。双交叉 13C 标记实验与完全分子内环化机制一致。氘标记实验支持涉及跨烯烃的顺式加成的机制。

  practical process for the direct conversion of nitriles to cyanamides was newly discovered and exhibited a wide substrate scope as well as great functional group-tolerability (36 examples). In this efficient strategy, the in situ generated amidoximes obtained from the reaction of nitriles with hydroxylamine subsequently underwent Tiemann rearrangement, producing the corresponding cyanamides with great
