A novel preparation of chiral 1,3-oxathianes via nucleophilic addition of hydroxy-thiols to electron-poor acetylenes, followed by iodine catalyzed photoinduced cyclization is reported. The stereochemical outcome of the reaction is determined with a conformationalstudy based on n.O.e. 1H-NMR differential spectroscopy experiments.
