A novel and efficient procedure for the synthesis of polysubstituted pyrroles has been developed in this work. The polysubsituted pyrroles were synthesized directly from terminal alkenes, amines and β-keto esters through cross-couplingâcyclizationâoxidation in the presence of a catalytic amount of cuprous chloride. This method provides a one-pot synthesis route from terminal alkenes to polysubstituted pyrroles for the first time and opens a new area in cuprous catalysis.
