The reaction of 2,3-disubstituted arylsulfonylaziridines with isocyanates in presence of sodium iodide yielding 4,5-disubstituted-2-imidazolidinones is somewhat specific rather than a general reaction, but whenever the reaction occurs, it does so in a totally stereospecific manner where imidazolidinones produced have the same geometric configuration as that of the starting aziridines.
