Oxidation of prochiral sulphonimines (RSO2N = CHAr) with (1S)-(+)-PCA, followed by fractional crystallization of the crude reaction products, provides highly optically-pure N-sulphonyl-3-aryloxaziridines 1H-NMR spectra recorded in the presence of chiral solvent or shift reagent, CD spectra, and the results observed by using them as new chiral oxidizing reagents, are also reported.
