A series of 2‐oxazinones 1‐8 were synthesized from the cycloaddition reactions of oxetanes with isocya‐nates by utilizing the complex of diphenyltin diiodide with hexamethylphosphoric triamide (HMPA) as a catalyst. Moreover, the reactions with carbodiimides proceeded under milder conditions with the same catalyst system, and gave 2‐iminooxazines, 9 and 10 , in high yields.
