A novel practical synthesis of N-aryl-substituted azacycles from arylhydrazines is described. In this method, target azacycles were prepared via reaction of arylhydrazines with cyclic ethers in the presence of both titanium(IV) chloride and 1,5,7-triazabicyclo[4.4.0]dec-5-ene (TBD) as key combined reagents. Using this synthetic protocol with titanium(IV) chloride and TBD, reaction of arylhydrazines
描述了一种由芳基肼合成N-芳基取代的氮杂环的新实用合成方法。在该方法中,通过芳基肼与环醚在氯化钛 (IV) 和 1,5,7-三氮杂双环[4.4.0]dec-5-ene (TBD) 作为关键组合试剂的存在下反应制备目标氮杂环化合物. 使用这种与氯化钛 (IV) 和 TBD 的合成方案,芳基肼与环醚的反应成功地以高产率提供了各种N-芳基取代的氮杂环。这种使用芳基肼的简便合成方法将为从芳基肼合成氮杂环化合物提供有希望的指导。
