A metal-free cyclization of N-propargylamides for the synthesis of various oxazolines and oxazoles via a 5-exo-dig process is presented. Using (diacetoxyiodo)benzene (PIDA) as a reaction promoter and lithium iodide (LiI) as an iodine source, intramolecular iodooxygenation of N-propargylamides proceeded readily, leading to the corresponding (E)-5-iodomethylene-2-oxazolines in good to excellent isolated

visible light irradiation. Twelve 2-aryl oxazole-5-carbaldehydes, six of them so far unpublished, were formed in 30–90 % yield, from various N-(propargyl)benzamides in the reaction with benzeneseleninic acid in the presence of eosin Y. Notably, the coproduct diphenyl diselenide is quantitatively recovered and can be reused.
