In the presence of 1.1 equiv of (Diacetoxyiodo)benzene (PIDA) and suitable halogen sources, a variety of olefins underwent haloamidation, haloetherification, and halolactonization to the corresponding 1,2-bifunctional cyclic skeletons in very good isolated yields. Subsequent mild nucleophilic substitution gives key intermediates for biologically interesting compounds in high yields.
