  Treatment of diamides derived from α-amino acids with phosphorus pentasulfide or Lawesson's reagent was shown to provide a convenient method to prepare 5-aminothiazoles. By this method, in addition to mono-cyclic 5-aminothiazoles 19, novel bicyclic 5-aminothiazole derivatives such as 4,5,6,7-tetrahydrothiazolo[5,4-b]pyridines 11, 5,6,7,8-tetrahydro-4H-thiazolo[5,4-b]azepines 7, 4,5,6,7,8,9-hexahydrothiazolo[5

  结果表明，用五硫化二磷或Lawesson试剂处理α-氨基酸衍生的二酰胺可为制备5-氨基噻唑提供便利的方法。通过该方法，除了单环5-氨基噻唑19，新的双环5-氨基噻唑衍生物，如4,5,6,7-四氢噻唑并[5,4- b〕吡啶11，5,6,7,8-四氢-4- ħ -噻唑并[5,4- b ]吖庚因7，-4,5,6,7,8,9- hexahydrothiazolo并[5,4- b ]吖辛因16在中等制备到从简单的良好的产率和相关的化合物双酰胺，表明该方法具有广泛的通用性。

  The synthesis of N‐acylurea derivatives through the silver‐catalyzed coupling of readily available dioxazolones with isocyanides and water has been reported. The desired products were obtained in moderate to good yields. The reaction can be performed on gram scale. The 18O‐labelling experiment shows that water participates in this reaction. A possible reaction mechanism is proposed in which carbodiimide

  A highly enantioselective (49–99% ee) Michael addition/lactonization cascade process has been developed to construct 3,4-dihydropyran-2-one in the presence of a bifunctional squaramide. Various α,β-unsaturated N-acyl heterocycles were well tolerated and afforded 3,4-dihydropyran-2-ones in moderate to excellent isolated yields (50–99%). Both cyclic and acyclic β-diketones functioned as appropriate donors

  已经开发了一种高度对映选择性（49-99％ee）的迈克尔加成/内酯化级联方法，可在双功能方酰胺存在下构建3,4-二氢吡喃-2-酮。各种α，β-不饱和N-酰基杂环具有良好的耐受性，并以中等至极好的分离产率（50-99％）提供了3,4-二氢吡喃-2-酮。环状和非环状的β-二酮都可以作为合适的供体。所得的3，4-二氢吡喃-2-酮可容易地转化为草并cali醛。

• Hydroxamic Acids Block Replication of Hepatitis C Virus
  作者：Teng Ai、Yanli Xu、Li Qiu、Robert J. Geraghty、Liqiang Chen

  DOI：10.1021/jm501330g

  日期：2015.1.22

  Intrigued by the role of protein acetylation in hepatitis C virus (HCV) replication, we tested known histone deacetylase (HDAC) inhibitors and a focused library of structurally simple hydroxamic acids for inhibition of a HCV subgenomic replicon. While known HDAC inhibitors with varied inhibitory profiles proved to be either relatively toxic or ineffective, structureactivity relationship (SAR) studies on cinnamic hydroxamic acid and benzo[b]thiophen-2-hydroxamic acid gave rise to compounds 22 and 53, which showed potent and selective anti-HCV activity and therefore are promising starting points for further structural optimization and mechanistic studies.
