CuI/TBHP: A versatile reagent system for the synthesis of 5-iodomethyl-2-aryl-4,5-dihydrooxazoles from <i>N</i>-allylarylamides

<p>Herein, a novel reagent system using CuI/TBHP is described for the facile conversion of easily accessible <i>N</i>-allylarylamides into 5-iodomethyl-2-aryl-4,5-dihydrooxazoles in moderate to good yields. In this communication we describe CuI as the iodine source for the first time towards the intramolecular iodooxygenation of <i>N-</i>allylarylamides.</p
