The tandem hydroamination–annulation reaction of 4-pentyne-nitriles in the presence of amine nucleophiles and a cooperatively operating catalyst system, consisting of Ph3PAuCl and Zn(ClO4)2, provides an efficient route to 2-aminopyrroles. Two regioisomeric 2-aminopyrroles were formed in moderate to good yields.
在胺亲核试剂和由 Ph3PAuCl 和 Zn(ClO4)2 组成的协同操作催化剂体系存在下,4-戊炔腈的串联氢胺化-成环反应提供了一条有效的途径制备 2-氨基吡咯。两种区域异构体2-氨基吡咯以中等至良好的产率形成。
