A new iron-catalyzed chemoselective intramolecular hydroamination and hydroalkoxylation of the readily available α-allenic amines and alcohols to valuable unsaturated 5-membered heterocycles, 2,3-dihydropyrrole and 2,3-dihydrofuran, is reported. Effective selectivity control is achieved by a metal–ligand cooperative activation of the substrates. The mild reaction conditions and the use of low amounts
报道了一种新的铁催化的化学选择性分子内加氢胺化反应,以及将容易获得的α-烯丙胺和醇加氢成有价值的不饱和5元杂环,2,3-二氢吡咯和2,3-二氢呋喃的方法。有效的选择性控制是通过底物的金属-配体协同活化来实现的。温和的反应条件和少量空气和水分稳定的铁催化剂的使用,使得在不存在碱或任何敏感添加剂的情况下,能够以良好的收率对各种带有不同官能团的烯进行加氢官能化。
