Abstract The fragmentation of 1,3-oxazolidines under electron-impact and chemical-ionization (with methane as the gas reagent) conditions and the effect of the substituent in the 2 position of the heteroring on the stability of the molecular ions (M+) and on the character of the fragmentation of 1,3-oxazolidines were studied. It is shown that splitting out of an alkyl group from the 2 position is characteristic for electron impact. Processes involving alkylation and protonation with the formation of cluster ions are most characteristic for chemical ionization. In analogy with hydrolysis in the condensed phase, protonated 1,3-oxazolidine molecules split out an aldehyde molecule.
