  α-ketoacetals, tosyl hydrazide, and a primary amine. Functional group tolerance is outstanding in both the α-ketoacetal and amine coupling partners providing access to 4-, 1,4-, 1,5-, and 1,4,5- substituted triazoles in excellent yield. This robust method results in densely functionalised 1,2,3-triazoles that remain challenging to prepare by azide-alkyne cycloaddition (AAC, CuAAC, RuAAC) methods and can be scaled

  已开发出一种可扩展的，无金属，无叠氮化物和无卤素的方法，用于合成取代的1,2,3-三唑。该反应通过α-酮缩醛，甲苯磺酰脲和伯胺的3组分偶联而进行。在α-酮缩醛和胺偶合伙伴中，官能团的耐受性均十分出色，从而能够以优异的产率获得4-，1,4-，1,5-和1,4,5-取代的三唑。这种稳健的方法导致了稠密官能化的1,2,3-三唑，这些化合物仍然难以通过叠氮化物-炔烃环加成（AAC，CuAAC，RuAAC）方法制备，并且可以在间歇式或流式反应器中进行规模化。还描述了脂族胺或苯胺的化学选择性反应的方法，揭示了这种新颖且用途广泛的转化的一些潜力。
