Abstract:

N-aryl derivative is an important motif prevalent in natural products and drugs. A fibroin assisted copper-promoted C-N coupling reaction using aryl halides and imidazole to afford the N-aryl compounds in excellent yields was reported. The reaction could be scaled up to multi-gram quantities and used to synthesize 2-phenylindole and 1,2,3-1H-triazole. The reaction mechanism was proposed based on the previous reports.

Key words: Fibroin, Copper, C-N coupling, Ligand
