| Abstract: | A novel and efficient one‐pot procedure was designed for the sulfonyloxylactonization of alkenoic acids by the reaction of alkenoic acids with m‐chloroperbenzoic acid and sulfonic acids in the presence of a catalytic amount of ammonium iodide 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 yields. |
