title: (Diacetoxy)iodobenzene-Mediated Oxidative C-H Amination of Imidazopyridines at Ambient Temperature.
abstract: (Diacetoxy)iodobenzene (PIDA)-mediated direct oxidative C-H amination for the synthesis of 3-amino substituted imidazopyridines has been achieved under metal-free conditions at room temperature in short reaction times. This methodology is also applicable for the regioselective amination of indolizines. Experimental results suggest that the reaction likely proceeds through a radical pathway.
