A one-pot multicomponent reaction for the synthesis of 3-sulfenylimidazo[1,2-a]pyridines from readily available 2-aminopyridines, ketones, and sulfonyl hydrazides, mediated by molecular iodine, has been developed. The transformations proceed smoothly with high efficiency and a broad substrate scope, affording the desired heterocyclic products in moderate to excellent yields.
