A novel method for the synthesis of highlysubstituted iodine-containing furans has been developed by the cyclization of 1-(aryl ethynyl)-2,3 -epoxy alcohols (1-aryl-4,5-epoxyalk-1-yn-3-ols) with alcohols as nucleophiles under very mild reaction conditions. The resulting iodine-containing furans can be readily elaborated to more complex products using known organopalladium chemistry.
