Copper(II)/Iron(III) Co-catalyzed Intermolecular Diamination of Alkynes: Facile Synthesis of Imidazopyridines
摘要:
A facile synthesis of imidazo[1,2-alpha]pyridines has been achieved by copper(II) and iron(III) co-catalyzed C-N bond formation. This reaction involves an intermolecular oxidative diamination of alkynes with high chemoselectivity and regioselectivity.
