IR and NMR spectra of some 2-aryl-thiazolidine-4-carboxyli acids and MS spectra of two of them have been recorded. As indicated by IR, the 2-aryl-thiazolidine-4-carboxylic acids in solid state mainly exist in the zwitterion form. These compounds are rather stable and a considerable similarity among them in cleavage were found in MS spectra. The NMR spectra revealed the existence of diasteroisomers for these compounds and the influence of the substituents on the electron density of the carbon atoms of the benzere ring is much greater than on that of the thiazolidine ring.
