Synthesis and evaluation of the anti-microbial activity of new heterocycles containing the 1,3,4-thiadiazole moiety.
A new series of thiadiazole-enaminones 4 were synthesized via reactions of 5-acetyl-1,3,4-thiadiazoles 3 with dimethylformamide-dimethylacetal (DMF-DMA). The simple phenyl substituted thiadiazole-enaminone 4f was used as a synthetic precursor for the preparation of a wide variety of new heterocyclic compounds, including the 5-substituted-1,3,4-thiadiazole derivatives 5, 6, 11, 12 and 13, which ...

متن کاملSynthesis and Microbial Studies of Some New Oxygen Heterocycles
In an attempt to find a new class of antimicrobial agents, a series of oxygen heterocyclic isocoumarins, dihydroisocoumarins, aromatic / aliphatic amino methyl isocoumarin derivatives having benzoyl group at 3 position in isocoumarin moiety was synthesized using simple appropriate starting material o-acyl benzoic acid and bromoacetophenone derivatives in presence of anhy. K2CO3 in ethyl methyl ...
