The visible light promoted C–H sulfonylmethylation of imidazopyridines with easily accessible bromomethyl sulfones under mild reaction conditions was described. This protocol provides an effective and practical access to sulfonylmethylated imidazopyridines with good functional group tolerance. The desired products were provided in moderate to excellent yields for 50 examples at room temperature. The method could also be an attractive strategy to install a methyl group on imidazopyridines.

An iron(III)-catalyzed one-pot three-component cross-coupling nitration reaction of 2-aminopyridines, aldehydes and nitroalkanes, straightforwardly forms imidazo[1,2-a]pyridine derivatives and is described in this report. The system shows good functional-group tolerance and proceeds smoothly in moderate to good yields. An iron(III)-catalyzed one-pot three-component cross-coupling nitration reaction of 2-aminopyridines, aldehydes, and nitroalkane, leading to the straightforward formation of imidazo[1,2-a]pyridine derivatives has been reported. In this procedure, the starting materials are commercially available. The system shows good functional-group tolerance and proceeds smoothly in moderate to good yields. Copyright
