An efficient synthesis of 2-(perfluoroalkyl)pyrroles that employs a sequential one-pot three-component reaction between substituted ω-bromoacetophenones, anilines, and methyl perfluoroalk-2-ynoates has been developed. This transition-metal-free cascade process provides a practical way to construct perfluoroalkylated pyrroles in moderate to good yields.

A new, general copper-catalyzed oxidative tandem [4+2] cycloaddition of α-(N-arylamino) carbonyl compounds with aryl alkenes to produce highly substituted quinolines has been developed, which allows the formation of three new C–C bonds through a sequence of multiple C–H functionalizations, annulation, and [1,2]-aryl shifts.
