A novel and efficient one‐pot procedure was designed for the sulfonyloxylactonization of alkenoicacids by the reaction of alkenoicacids with m‐chloroperbenzoic acid and sulfonic acids in the presence of a catalytic amount of ammoniumiodide in a mixture acetonitrile/2,2,2‐trifluoroethanol (4 : 1) at room temperature for 24 h, which provided the corresponding sulfonyloxy lactones in moderate‐to‐good
