A tri‐umph in many respects: The iron‐catalyzed ligand‐free, one‐pot three‐component coupling reactions of aldehydes, terminal alkynes, and amines in the presence of 4 A molecular sieves yields the corresponding propargylamines in good to excellent yields, displays a broad substrate scope, and is economical and environmentally friendly (see scheme).
在许多方面都做到了三步走:在4 A分子筛的存在下,铁,醛,末端炔烃和胺的无铁催化的单锅三组分偶联反应可产生相应的炔丙基胺,收率好至极好,显示基材范围广,经济且环保(请参阅方案)。
