Good nucleophilicity of the ring nitrogen in chiral (2R,1'R)-2-acyl-(1'-phenylethyl)aziridines initiated the reaction with various acid chlorides to form the corresponding acylaziridinium ion intermediates whose rings were opened by the chloride anion to yield the beta-amino-alpha-chlorocarbonyl compounds. The subsequent displacement of the chloride with the internal oxygen nucleophile originated from methylchloroformate, acetyl chloride, and methyl chlorooxoacetate yielded oxazolidin-2-ones, beta-amino-alpha-acetyloxypropionates, and morpholin-2,3-diones, respectively.
