Synthesis and antimicrobial properties of novel 2,5-disubstituted 1,3,4-oxadiazoles
The search for better antimicrobial agent due to rapid appearance of multidrug resistant microorganism and antimicrobial properties of semicarbazones and 2,5-disubstituted 1,3,4-oxadiazoles prompted us to undertake the synthesis of a few novel N-[5-(4-substitutedphenyl)-1,3,4-oxadiazol-2-yl]-N-(4substitutedbenzaldehyde)-semicarbazone and N-[5-(4-substitutedphenyl)-1,3,4-oxadiazol-2-yl]-N-[1-(4s...
متن کاملA Simple, Practical and Efficient Method for the Synthesis of New Disubstituted 1,3,4-oxadiazoles
Reactions of N-isocyaniminotriphenylphosphorane with α- chloroketones in the presence ofaromatic carboxylic acids proceed smoothly at room temperature and in neutral conditions toafford new disubstituted 1,3,4-oxadiazole derivatives in high yields.

متن کاملReaction of 2 , 5 - Disubstituted - l , 3 , 4 - oxadiazoles
Some 5-aryl-2-mercapto-1,3,4-oxadiazole (I) reacted with maleic anhydride, maleic acid and p-benzoquinone affording 2-(5-aryl-1,3,4-oxadiazol-2-ylthio)succinic anhydrides (II), 2-(5-aryl-1,3,4-oxadiazol-2-ylthio)succinic acids (III) and 2-(2,5-dihydroxyphenylthio)-5-aryl-l,3,4-oxadiazoles (IV), respectively. Treatment of 2-methylthio-5-phenyl-l,3-oxadiazole (V) with amines gives 2-[(alkyl or ar...
متن کاملSynthesis, characterization, antimicrobial and antioxidant activity of some disubstituted [1,3,4]-oxadiazoles carrying 4-(methylsulfonyl/sulfinyl)benzyl moieties
Disubstituted [1,3,4]-oxadaiazoles (6a-b), Mannich bases (7a-f) and S-alkylated derivatives (8a-f) have been synthesized from 4-(methylsulfonyl/sulfinyl)phenylaceticacid (3a-b) through a multi-step reaction sequence starting from (4-methylthio)phenylacetonitrile (1). The structures of new compounds were established on the basis of their elemental analysis, IR, H NMR, C NMR and mass spectral dat...
