A one-pot three-component reaction of several 2-ketoaldehydes, secondary amines and terminal alkynes to access 3-aminofurans proceeded well in [bmim][PF6] using a simple and cheap CuI catalyst. The resultant 3-aminofuran products were easily isolated using diethyl ether and the CuI/[bmim][PF6] system was reused six times with a slight decrease in the activity.
使用简单且廉价的 CuI 催化剂,在 [bmim][PF 6 ]中,几种 2-酮醛、仲胺和末端炔烃与 3-氨基呋喃的一锅三组分反应进行得很好。生成的 3-氨基呋喃产物很容易用乙醚分离,CuI/[bmim][PF 6 ] 体系重复使用六次,活性略有下降。
