A FACILE SYNTHESIS OF N-ARYL AZIRIDINES

Reaction of N-aryl-β-amino alcohols with p-toluenesulphonyl chloride under phase transfer catalytic condition gave the corresponding N-aryl aziridines in good yields, whereas N-alkyl-β-amino alcohol for e.g., L-ephedrine] gave the corresponding N-tosyl derivative as the major product, along with the expected N-alkyl aziridines in lower yield.
