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4A分子筛存在下,醛、末端炔烃和胺的铁催化无配体一锅三组分偶联反应能以良好至优异的产率生成相应的炔丙胺,底物范围广泛,且经济环保(见方案)。
