Enamine esters or ketones could undergo homocoupling by the action of (diacetoxyiodo)benzene in the presence of BF 3 -OEt 2 , giving rise to pyrrole products. This reaction could be used to synthesize symmetric polysubstituted pyrroles. Some asymmetric polysubstituted pyrroles could also be prepared using this protocol.
