3-triazoles were conveniently and quantitatively prepared by 1,3-dipolar cycloaddition of heterocyclic ketene aminals with fluoroalkanesulfonyl azide, followed by elimination of fluoroalkanesulfonyl amide at room temperature without any catalyst. fluoroalkanesulfonyl azide - ketene aminals - 1,3-dipolar cycloaddition - heterocycles - 1,3-diazaheterocycle-fused 1,2,3-triazole
通过与氟代链烷磺酰基叠氮化物将杂环烯酮缩醛的1,3-偶极环加成,然后在室温下不用任何催化剂消除氟代链烷磺酰基酰胺,可方便地定量制备一系列1,3-二氮杂杂环稠合的1,2,3-三唑。 氟烷磺酰基叠氮化物-乙烯酮缩醛-1,3-偶极环加成-杂环-1,3-二氮杂杂环稠合的1,2,3-三唑
