Oxygenation of various aldimines with tetrabutylammonium monoperoxysulfate produced the corresponding E- or a Mixture of E- and Z-oxaziridines with very high yields (greater than or equal to90%) and good to excellent selectivities (75-100%) within 20 min to 10 h in CH3CN at room temperature (similar to25 degreesC). The E/Z isomer ratio critically depends on the stereo-electronic nature of the substituents in the oxaziridines, solvent, and the presence of Lewis acids and bases. (C) 2003 Elsevier Ltd.
