✦ Synopsis

The mass spectrometric behaviour of 11 2-aryl-thiazolidine-4-carboxylic acids has been studied under electron impact conditions. On the basis of our high-and low-resolution measurements, deuterium labelling experiments and collision-induced dissociation studies the main fragmentation pathways have been established. In the high resolution spectrum of 2-phenyl-thiazolidine-4-carboxylic acid several peaks were found to be doublets. Some of the chemical formulae were unexpected. With the help of tandem mass spectrometry the formation of these ions was explained.

Fragmentation pathways of the title compounds were studied using accurate mass measurements and collision-induced dissociation spectra. Substituents in the ortho position of the aryl group at the pyrimidine ring were found to play a special role in the electron impact (EI) induced fragmentation of t
