摘要:
A three-component reaction of one molecule of imine and two molecules of allcynoates is realized with the catalysis of Cu(I) Fe(III) in a sequential manner to allow the direct synthesis of functionalized pyrroles, during which, one C-N bond and two C-C bonds are formed with high atom economy. This method benefits from easily available starting materials, low-cost catalysts, and convenient operations. (C) 2014 Published by Elsevier Ltd.
