In this work, the synthesis of novel triazole derivatives with barbi­turic motifs in good yields is described. The alkyne was prepared through the Knoevenagel reaction of barbituric derivatives with ortho and para O-propar­gylated hydroxybenzaldehyde. The... see more

The synthesis of a series of new 4-amino-5-alkyl-1,2,4-triazole(4H)-3-yl thioacetanilides and 4-pyrrolyl-5-alkyl-1,2,4-triazole(4H)-3-yl thioacetanilides has been described in the article. The key intermediates – 4-amino-5-alkyl-3-mercapto-1,2,4-triazoles... see more

The synthesis of a series of new 4-amino-5-alkyl-1,2,4-triazole(4H)-3-yl thioacetanilides and 4-pyrrolyl-5-alkyl-1,2,4-triazole(4H)-3-yl thioacetanilides has been described in the article. The key intermediates – 4-amino-5-alkyl-3-mercapto-1,2,4-triazoles... see more

Reactions of [5+1]-cyclocondensation of [2-(3-aryl-1H-1,2,4-triazol-5-yl)phenyl]amines with aliphatic and aromatic aldehydes produce the corresponding 5-R-2-aryl-5,6-dihydro- or 5-R-2-aryl-[1,2,4]triazolo[1,5-?]quinazolines depending on the cond... see more

The article is devoted to investigation of coordination compounds of palladium (II) with 3-(2-pyridyl)-1,2,4-triazole derivatives containing amino groups. We syntesized 4 ligands and 4 new coordination compounds. An interesting after removing of BOC-prote... see more

The development of new preparations in soft medical form with antifungal effect and the ability to exert an antimicrobial effect on the secondary microflora accompanying the infection with accompanying desensitizing action is extremely relevant, as well a... see more

Features of 5-trichloromethyl-2-aryl-5,6-dihydro-[1,2,4]triazolo[1,5-c]quinazolines formation as result of [5+1]-cyclocondensation of the corresponding [2-(3-aryl-1H-1,2,4-triazole-5-yl)phenyl]amines with chloral hydrate are described in the article. It h... see more

?etalcarbene compounds of a series of [1,2,4] and [1,2,3]triazoles have been synthesized to study their antimicrobial activity. Monocarbene complexes of palladium (9a) and copper(I) (9b,12,15), biscarbene complexes of palladium (4a) and copper(I) (4b,14),... see more

Nitrilimines (2a-e) react with aldehydemethoxycarbonylhydrazones (3-5) to afford 3-acetyl-5-alkyl-1-aryl-4-(methoxycarbonylamino)-4,5-dihydro-1H-1,2,4-triazoles (6-8a-e). Thestructure of these compounds was elucidated by IR, MS and NMR spectraldata.
