Synthesis of Quinolyl Substituted Thiazolidines and Dihydrothiazoles Based on 2-{1-[2-Methyl-4-(methylthio)- quinolin-3-yl]propan-2-ylidene}hydrazinocarbothioamides Substituted in the Benzene Ring

The diverse biological activity of heterocyclic compounds makes them one of the most important areas of pharmaceuticals and organic synthesis. In this work, a synthesis of new hetarylquinolines containing thiazolidine and dihydrothiazole rings was carried out on the basis of 2-{1-[2-methyl-4-(methylthio)-quinolin-3-yl]propan-2-ylidene}hydrazinocarbothioamides substituted in the benzene ring. The synthesis was conducted using readily available and non-toxic starting materials, ensuring a practical and accessible methodology. The results of this work may serve as a foundation for further studies aimed at exploring the biological and applied potential of these compounds.
