Synthesis of 3-Nitro-2-arylimidazo[1,2-a]pyridines Using Sodium Dichloroiodide
摘要:
Moderate to good yields of various 3-nitro-2-arylimidazo[1,2-a]pyridines have been easily achieved in the reaction of 2-aminopyridines and nitrostyrenes in the presence of sodium dichloriodide. The procedure is simple and various functional groups are tolerated in this reaction system.
A copper-catalyzed method for the synthesis of imidazo[1,2-a]pyridines with aminopyridines and nitroolefins using air as oxidation agent in a one-pot procedure has been developed. In this process, the reaction appears to be very general and suitable for construction of a variety of imidazo[1,2-a]pyridines.

Bu4NI-Catalyzed Synthesis of Imidazo[1,2-a]pyridines via Oxidative Coupling of Aminopyridines with Nitroolefins
A metal-free method for the synthesis of imidazo[1,2-a]pyridines via double C–N oxidativecoupling of aminopyridines with nitroolefins using TBAI as the catalyst and TBHP as oxidation agent has been developed.
Metal-free synthesis of imidazopyridine from nitroalkene and 2-aminopyridine in the presence of a catalytic amount of iodine and aqueous hydrogen peroxide
We have developed a metal-free synthetic method for 3-nitroimidazo[1,2-a]pyridines from nitroalkenes and 2-aminopyridines using catalytic amounts of iodine and aqueous hydrogen peroxide as a terminal oxidant.
