摘要
A novel series of ethyl-2-(3-((2-(4-(4-aryl)thiazol-2-yl)hydrazono)methyl)-4-hydroxy/isobutoxyphenyl)-4-methylthiazole-5-carboxylate derivatives (4a-f and 5a-f) were synthesized by employing one-pot multi-component approach involving ethyl 2-(3-formyl-4-oxy/isobutoxyphenyl)-4-methylthiazole-5-carboxylate, thiosemicarbazide and various phenacyl bromides/3-(2-bromoacetyl)-2H-chromen-2-one/2-(2-bromoacetyl)-3H-benzo[f]chromen-3-onein ethanol in the presence of catalytic amount of acetic acid. The structures of all the synthesized compounds were confirmed with spectral analysis, ie, IR, 1H NMR, 13C NMR and mass spectrometry, and all the compounds were screened for their in vitro antimicrobial activity.
