A new method for the iodocyclization of olefinic dicarbonyl compounds with t-butyl hydroperoxide (TBHP) and I2 was developed. The in situ generated hypoiodous acid and tBuOI were used as active iodine cation reagents. This method allowed the synthesis of polysubstituted 5-iodomethyldihydrofurans under mild reaction conditions with cheap reagents and high atom economy.
