Iodolactonization of gamma,delta-unsaturated anilides 2 in the presence of water and subsequent reduction of the resultant iodolactones 3 using zinc in acetic acid yield the carboxylic acids 4 without significant epimerization alpha to the carbonyl group. The diastereoselectivity inherent in iodolactonizations of anilides 2 resembles the kinetic stereoselection found for the corresponding transformations of related carboxylic acids.
