Abstract
Various types of five-membered heterocyclic compounds such as 2-iminodioxolanes, 2-oxazolidinones, and 2-iminooxazolidines, can be obtained from the cycloaddition of oxiranes with isocyanates or carbodiimides catalyzed by organotin iodide-Lewis base complexes under very mild conditions (40°C, 2h).Keywords
