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.
Trisubstituted bicyclic heterocyclic compounds (e.g., chromenones and quinolines) and pharmaceutical compositions that modulate kinase activity, including PI3 kinase activity, and methods of treatment of diseases and conditions associated with kinase activity, including PI3 kinase activity, are described herein.
