  摘要：

  We describe herein a novel series of 3-amino-4-hydrazine-cyclobut-3-ene-1,2-diones as potent and selective inhibitors against the CXCR2 chemokine receptor and IL-8-mediated chemotaxis of a CXCR2-expressing cell line. Furthermore, these alkyl-hydrazine series inhibitors such as 5b demonstrated acceptable metabolic stability when incubated in human and rat microsomes. (C) 2009 Published by Elsevier Ltd.

  The synthesis of N-alkyl-1H-1,2,4-triazoles from N,N-dialkylhydrazones and nitriles via formal [3+2] cycloaddition including the C-chlorination/nucleophilic addition/cyclisation/dealkylation sequence was developed. This sequential reaction utilising the in situ generation of hydrazonoyl chloride based on the ambiphilic reactivity of hydrazones afforded a variety of multi-substituted N-alkyl-triazoles

  合成ñ -烷基-1 ħ从-1,2,4-三唑Ñ，Ñ -dialkylhydrazones和腈经由正式[3 + 2]环加成，包括Ç -chlorination /亲核加成/环化/脱烷基化序列被开发。这种基于腙的双亲反应性原位生成腙酰氯的连续反应以高产率提供了多种多取代的N-烷基-三唑。多取代三唑的合成效用也通过进一步的转化得到了证明。
