The novel reaction of [hydroxyl (((+)‐10‐camphorsulfonyl)oxy)iodo]benzene (1) with alkenoic acids was reported. When 1 reacted with various 4‐pentenoic acids in CH 3 CN, 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 reacted with 1 slowly in CH 2 Cl 2 , only unsaturated lactones were provided.
