The novel reaction of [hydroxyl (((+)‐10‐camphorsulfonyl)oxy)iodo]benzene (1) with alkenoicacids was reported. When 1 reacted with various 4‐pentenoic acids in CH3CN, camphorsulfonylactons were obtained in excellent yields in short times, some had two diastereoisomers, whereas 1 reacted with 5‐hexenoic acid, giving middle yield of camphorsulfonylacton; however, 3‐butenoic and trans‐3‐hexenoic acids

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
