Synthesis and in vitro antioxidant activities of novel 4-(3-methyl-2- thienylmethyleneamino)-4,5-dihydro-1H-1,2,4-triazol-5-one derivatives with their acidic properties
In the present study 3-alkyl(aryl)-4-amino-4,5-dihydro-1H-1,2,4-triazol-5- ones 2a-i reacted with 3-methyl-thiophene-2-carboxyaldehyde to afford the corresponding 3-alkyl(aryl)-4-(3- methyl-2-thienylmethyleneamino)-4,5-dihydro- ... -
Synthesis of 1,2,4-Triazole derivatives and determination of protonation constant
A microwave irradiation method has been developed for the synhesis of some 1,2,4-triazole derivatives using environmentally benign solvent ethanol in open vessels. Twelve 1,2,4-triazole derivatives were synthesized in good ... -
Synthesis of novel triazol compounds containing isatin as potential antibacterial and antifungal agents by microwave and conventional methods
Özil, Musa; Menteşe, Emre; Yılmaz, Fatih; İslamoğlu, Fatih; Kahveci, Bahittin (Sage Publishing, 2011)Microwave irradiation has been used to accelerate the conversion of isatin (1a) and 5-nitroisatin (1b) into their Schiff bases 3-[5?-aryl(alkyl)- 2?,4?-dihydro-1?,2?,4?-triazol-3?-on- 4?-yl]iminoisatin (3a-g) and ... -
Synthesis of unsymmetrical 3,5-disubstituted 1,2,4-triazole derivatives with their pKa values
Bekircan, Olcay; İslamoğlu, Fatih; Menteşe, Emre; Kahveci, Bahittin (Chiminform Data S A, 2014)Acylhydrazones (2a-b) were synthesized by the condensation of iminoester hydrochlorides (1a-b) with benzhydrazide. the treatment of acylhydrazones With hydrazine hydrate afforded 4-amino-4H-1,2,4-triazoles. (3a-b). ... -
