J Org Chem. 2016 Mar 4;81(5):1778-85. doi: 10.1021/acs.joc.5b02429. Epub 2016 Feb 22.

Abstract

A copper-catalyzed and microwave-assisted synthesis of fully substituted pyrroles has been developed. A series of pentasubstituted pyrroles, especially α-arylpyrroles, could be obtained in moderate to good yields (up to 93%) through a tandem propargylation/alkyne azacyclization/isomerization sequence from readily available β-enamino compounds and propargyl acetates.
