Triazole derivatives constitute an important group of heterocyclic compounds have have been the subject of extensive study in the recent past. These compounds have shown a wide range of biological and pharmacological activities. In this work, new fused tricyclic 1-(3-nitrophenyl)-5,6-dihydro-4H-[1,2,4]triazolo[4,3-a][1,5]-benzodiazepines have been synthesized by the thermal cyclization of N'-(2...

The present work includes synthesis of new series heterocyclic derivatives containing 6-amino-1,3-dimethyl uracil moiety linked to 1,2,4-triazole [6-8 and 10]. first way reaction 6-amino-1,3-dimethyluracil with ethyl chloroacetate K2CO3 as catalyst in DMF solvent gives ester derivative [1]. Then, compound [1] was converted into (semicarbazide, thiosemicarbazide, phenylsemicarbazide hydrazide de...

The reaction of 5-(1-adamantyl)-4-amino-3-mercapto-1,2,4-triazole (5) with various aromatic aldehydes in ethanol or acetic acid yielded the corresponding 4-arylideneamino derivatives 6a-v. Treatment of the 4-(2,6-difluoro- and dichlorobenzylideneamino) derivatives 6o and 6q with 1-substituted piperazines, and formaldehyde solution in ethanol afforded good yields of the corresponding 5-(1-adaman...

A novel approach was carried to prepare trans-CuCl2L2 complex with the ligand L, (E)-(4-chlorophenyl)-N-(3-phenyl-4H-1,2,4-triazol-4-yl)methanimine which formed in situ during reaction of CuCl2 4-(4-chlorobenzylideneamino)-5-phenyl-2H-1,2,4-triazole-3(4H)-thione. The synthesized compounds were characterized by applying various spectroscopic techniques. crystal structure unambiguously determined...

The olefin moiety presents in styrylsulfonylmethyl-1,2,4-triazolylamine (1) was exploited to build up five-member heterocycle-pyrazoles. series of novel pyrazolyl-1,2,4-triazole amine derivatives (2-3) have been synthesized. All the entitles compounds were characterized by 1H and 13C NMR spectra.

Pesticides are used on a large scale for agricultural purposes. The adverse effects of pesticides on both human health and the environment are a matter of public concern. Thus both the actual state and residue levels of pesticides in agricultural products should be extensively monitored. One of the new classes of pesticide is the triazole derivatives, which are very effective fungicides. In thi...

Introduction: Searching for new compounds with anti-anxiety activity resulting from the combination of privileged scaffolds is a promising direction in medicinal chemistry and development drugs. Anxiolytic potential cytotoxic properties previously synthesized molecules, containing fragments 2,3-benzodiazepine 1,2,4-triazole – 6-(4-methoxyphenyl)-7H-[1,2,4]triazolo[3,4-A][2,3]benzodiazepines und...

2-(2-Alkoxycarbonyl-1-arylamino-1-propenyl)benzimidazolium and 5-(2-alkoxycarbonyl-1-arylamino-1-propenyl)triazolium salts were synthesized in good yields from the reaction of benzimidazole and triazole carbenes with ketenimines. Upon treatment with a base, both salts were converted into novel 1,3-dipoles which underwent [3+2] cycloaddition reactions with electron-deficient alkynes and allenes ...
