Abstract:

The addition of (chlorocarbonyl)phenyl ketene 2 to 5-alkylpyrazol-3(4H)-ones 1 led to the formation of 3-hydroxypyrazolo[1,2-a]pyrazole-dione/pyrazolo[1,2-a]pyrazole-trione derivatives 3. This is ascribed to hydrogen exchange in initially formed unstable, mesoionic pyrazolo[1,2-a]pyrazol-4-ium-5-olates. In contrast, condensation of the same ketene with 3-alkyl-1-phenyl-2-pyrazolin-5-ones 4 afforded 4-hydroxy-3-alkyl-1,5-diphenylpyrano[2,3-c]pyrazol-6-one derivatives 5. The latter reaction provides a new and rapid route to 4-hydroxy-2-pyrones fused to pyrazole rings, in good to excellent yields

Abstract:

3-Amino-4-cyanopyrazole I reacts with hydroxylamine and with hydrazine to yield 1H,6H-3-aminopyrazolo[3,4-c]pyrazole (III and IV). Diazotized IV couples with 2-naphthol to give the arylazo derivative VI which cyclizes to 9H-naphthol[2,1-e]pyrazolo[3',4':3,4]pyrazolo[5,1-c]-[1,2,4]triazine VII by means of acetic acid. The pyrazol-5-ylthiourea obtained from I and phenyl isothiocyanate undergoes base-catalyzed cyclization to give pyrazolo[3,4-d]pyrimidinethione derivative IX.

Abstract:

Synthetic access to 6,7-dihydro-4H-pyrazolo[5,1-c][1,4]oxazines has been achieved in 3–4 steps from commercially available pyrazoles. Optimization of a protected hydroxyethyl group on N1 enabled the regiocontrolled construction of pyrazole-5-aldehydes in high yields; subsequent deprotection and reduction generated fused heterocyclic scaffolds bearing multiple substitution patterns. Moreover, the intermediate pyrazole lactols were shown to be versatile synthetic building blocks.

Subsequent perfluoroacylations of the vinyl ethers followed by reaction of the resulting perfluoroacyl enol ethers with hydrazine affords a range of 5-aryl-3-perfluoroalkyl pyrazoles in good yields.;Alternative methodology for the synthesis of 5-aryl-3-perfluoroalkyl pyrazoles is then described

Abstract:

The bibliographic study of chalcones of the type 1,3-aryl(heteryl)propen-2-one with thiosemicarbazidic 4- and 1,4-disubstituted and thisemicarbazonic groups respectively gives us the information that they have a wide spectrum of biological activity, but methods of their synthesis are less described in the literature, and they became our object of study. 4,5-Dihydro-1-H-(pyrazol-3-yl)phenylhydrazinecarbothioamides 3a and 3b were obtained according to the following scheme:Reagents and reaction conditions: i, ii) 2-Py, 25oC – 24h, 90-95oC – 3h, 77-82%; iii) DMF, CH3COOH, 70-80oC, 2-3h, 60-63%.

Abstract:

The coordination properties of 3-(4-chlorophenyl)-1H-pyrazole (HL) was investigated and its complex with Ni(II) ion was synthesized. The structure of the ligand was proven using SC-XRD, while both the ligand and the complex were characterized by spectroscopic, and thermogravimetric measurements. The purity and composition of the complex were confirmed by PXRD, elemental analysis, and conductometric measurements. Besides, the search for CSD was made to establish the frequency of different coordination modes of similar compounds. It was found that monodentate coordination of the neutral ligand m

Abstract:

This mini-review summarizes the kinetic data obtained for the substitution reactions of some palladium(II) complexes containing bis-pyrazolylpyridine derivatives as pincer-type ligands with biologically significant nitrogen- and sulfur-donor biomolecules as nucleophiles. Three structurally different palladium(II) complexes were selected: [Pd(L1)Cl]+(Pd1), [Pd(L2)Cl]+(Pd2) and [Pd(L3)Cl]+(Pd3) (where L1 = bis(2-(1H-pyrazol-1-yl)ethyl)amine, L2 = 2,6-bis(5-(tert-butyl)-1H-pyrazol-3-yl)pyridine, and L3 = 2,6-bis(5-(tert-butyl)-1-methyl-1H-pyrazol-3-yl)pyridine, while for the entering nucleophiles
