CuCl catalyzed green and efficient one-pot synthesis of aminoindolizine frameworks via three-component reactions of aldehydes, secondary amines, and terminal alkynes in PEG
The one-pot three-component reaction of several 2-ketoaldehdyes, secondary amines and terminal alkynes to access 3-aminofurans was proceeded well in [bmim][PF6] using a simple and cheap CuI catalyst. The resulted 3-aminofuran...
