Abstract Fragmentations induced by collision‐activated dissociation of α‐ O ‐ and α‐ N ‐substituted oxazolidines are demonstrated under ammonia chemical ionization (CI) and electron impact (El) conditions. Discrimination of these regioisomers is achieved using either conventional EI mass spectra or daughter ion mass spectra of the protonated molecules under ammonia CI conditions.
