Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>A novel and efficient one‐pot procedure was designed for the sulfonyloxylactonization of alkenoic acids by the reaction of alkenoic acids with <italic>m‐</italic>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.</p> </abstract>
