Notes:
Thiazoles substituted in positions 2 and 4 by hydroxy, mercapto and amino groups were synthesized, as well as its carbamate derivates and formylhydrazones. The research of the reaction of the formylhydrazide with 4-imino-2-thiazolidinone has not given the pyrazolo [3,4-d]- thiazol-2-one, but the 4-formylhydrazono-2-thiazolidine. The detailed tautomeric study of each of the heterocyclic compounds has been carried out by infrared spectroscopy, nuclear magnetic resonance of proton and of 13-carbon, and of masses.
