A convenient CuI/DBU catalyzed one-pot method has been developed for the synthesis of 1,4-disubstituted 1,2,3-triazoles through the coupling of aryl iodides with sodium azide, followed by the intermolecular cyclization between the generated aryl azides and phenylacetaldehyde derivatives or alkynes in DMSO. The established protocol was compatible with a wide scope of substrates in good to excellent
通过芳基碘化物与叠氮化钠的偶合反应,然后在生成的芳基叠氮化物和芳烃之间进行分子间环化反应,已经开发了一种方便的CuI / DBU催化一锅法,用于合成1,4-二取代的1,2,3-三唑。 DMSO中的苯乙醛衍生物或炔烃。既定的方案以良好至优异的产率与广泛范围的底物相容。
