The first catalytic enantioselective iodoetherification of oximes is developed using commercially available N‐iodosuccinimide. In the presence of a dihydrocinchonidine‐derived thiourea (10 mol %), β,γ‐unsaturated oximes undergo facile iodoetherification to produce Δ2‐isoxazolines containing a quaternary stereogenic center generally in high yield with good to excellent enantioselectivity.
