Synthesis, potentiometric titrations and antioxidant activities of some 4-acylamino-4,5-dihydro-1H-1,2,4-triazol-5-one derivatives
Five novel 3-alkyl-4-cinnamoylamino-4,5-dihydro-1H-1,2,4-triazol-5-ones (2) were synthesized by the reactions of 3-alkyl-4-amino-4,5-dihydro-1H-1,2,4- triazol-5-ones (1) with cinnamoyl chloride and characterized by elemental ...
Photochemistry of nitro-substituted (E)-2-azachalcones with theoretical calculations and biological activities
Four new stereoselective dimerization products (4a-c, 5) of m- and p-nitro-substituted (E)-2-azachalcones (2 and 3) were synthesized and tested for antimicrobial and antioxidant activities. Compounds 1-3 showed very good ...
