An efficient one‐pot synthesis of 1,2,3‐triazoles via the three‐component coupling reaction between propargyl bromide, secondary amines, and 3‐azidopyridine in the presence of CuI as catalyst has been presented. The reaction is highly regioselective and afforded novel 1,4‐disubstituted‐1,2,3‐triazoles in excellent yields by the [3 + 2] Huisgen cycloaddition reaction. This method avoids isolation and
有人提出了在CuI作为催化剂的情况下,通过炔丙基溴,仲胺和3-叠氮基吡啶之间的三组分偶联反应,有效地一锅法合成1,2,3-三唑。该反应具有高度的区域选择性,并通过[3 + 2] Huisgen环加成反应以优异的收率提供了新型1,4-二取代-1,2,3-三唑。该方法避免了末端乙炔的分离和处理。纯化的简便性使该方法在广泛的范围内清洁,安全地合成1,2,3-三唑。
