Synthesis and evaluation of the antibacterial, antioxidant activities of novel functionalized thiazole and bis(thiazol-5-yl)methane derivatives

Novel functionalized thiazoles were prepared by the Hantzsch reaction from 3-[(4-hydroxyphenyl)carbamothioylamino]-2-methylpropanoic acid and the corresponding alpha-halocarbonyl compounds in good yields. A series of chemical transformations of the obtained products were carried out, and new functionalized thiazole derivatives with aliphatic, aromatic and heterocyclic substituents were synthesized. 4-Phenyl-substituted N-(4-hydroxyphenyl)-N-carboxyalkylaminothiazoles were used as precursors for the synthesis of bis(thiazol-5-yl)methane derivatives, which then were screened for their antibacterial, antioxidant activities.
