Synthesis, Structural Characterization, and Biological Evaluation of Novel Substituted 1,3-Thiazole Derivatives Containing Schiff Bases

Abstract

In this study, thiazole derivatives containing Schiff bases (7-9 a-f) were synthesized in moderate to high yields (49-94%) using the Hantzsch reaction with thiosemicarbazone derivatives (5a-c) and 2bromo- 1-phenylethanone derivatives (6a-f). The structures of synthesized compounds were elucidated by IR, H-1 NMR, C-13 NMR, elemental analyses, mass spectroscopy and X-ray diffraction analysis techniques. Moreover, the synthesized compounds were tested for their in vitro antifungal activity and most of them exhibited moderate to good activity against Fusariumoxysporumf.sp. lycopersici.
