A series of novel 1,2,3-thiadiazolo-5-carboxylic acid hydrazide Schiff’s bases 4a–4r were prepared starting from ethyl-4,4,4-trifluoroacetoacetate and ethyl carbazate in four steps. All the compounds were screened for antibacterial activity against various bacterial strains at 150 μg/ml concentration and found no activity. Similarly, all the compounds were(More)
The present article describes synthesis of new diethyl 2,6-dimethyl-4-(4-(2-substituted amino-2-oxoethoxy) phenyl)-1,4-dihydropyridine-3,5-dicarboxylates (6a–10b) following multistep synthetic route. Structures of newly synthesized intermediates and title compounds were established by spectral and elemental analyses. The final compounds were screened for(More)
