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.
cross-coupling reaction between α-amino carbonylcompounds and azoles by copper catalysis using di-tert-butyl peroxide (DTBP) as an oxidant is described. A diverse range of azoles undergo the dehydrogenative imidoylation smoothly with various α-amino carbonylcompounds for the exclusive formation of the corresponding N-imidoyl azoles in high yields under air. The synthetic method has the advantages of good

A novel copper‐catalyzed oxidative alkylation of α‐amino carbonyl compounds with ethers has been established for the selective synthesis of α‐etherized α‐amino carbonyl compounds. This oxidative alkylation is achieved by dual C(sp3)H bond oxidative cross‐coupling, and its scope is expanded to α‐amino ketones, α‐amino esters and α‐amino amides.

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.
