چکیده
А para-chlorophenyl substituent was firstly obtained into the structure of pyridyl-substituted 4-nitrosopyrazole by cyclocondensation hydrazine hydrate with corresponding isonitroso-β-dicarbonyl compounds. The previously unknown 3(5)-(4-chlorophenyl)-5(3)-pyridine-(3(4))-yl-4-nitroso-1H-pyrazoles and 3(5)-alkyl(aryl)-5(3)-pyridine-(3(4))-yl-4-nitroso-1H-pyrazoles is proved studied in detail modern methods analysis: mass spectrometry, 1H- 13C NMR-spectroscopy

Synthesis of Substituted 2-Pyridyl-4-phenylquinolines
Abstract: The acid-catalyzed condensation of o-aminobenzophenones with aromatic acetyl derivatives, in a basic methanol/tetrahydrofuran medium, has been used to prepare a series of substituted 2-pyridyl-4-phenylquinolines. Derivatives having two aza binding sites can act as asymmetric bidendate ligands to complex transition metals such as ruthenium, osmium or iridium. All the compounds were cha...
متن کاملEfficient Synthesis and Antimicrobial Activity of 2-Pyridyl-4-thiazolidinones from 2-Chloro Nicotinaldehydes
Several new 2-pyridyl-4-thiazolidinones are synthesized in an efficient manner evading using any catalyst or base. Simple workup procedure, good yields, and mild reaction conditions are the salient features of this method. All the synthesized compounds are screened for antimicrobial activity against several organisms.

Selective synthesis of 4-(sulfonyl)-methyl-1H-pyrazoles and (E)-4,5-dihydro-1H-pyrazoles from N-allenic sulfonylhydrazones with sulfonyl group migrations has been developed. A key feature of these reactions is that the migrations of the sulfonyl groups to different positions can be controlled by changing the Lewis acids.

15 صفحه اولSynthesis of Dihydrooxepino[3,2-c]Pyrazoles via Claisen Rearrangement and Ring-Closing Metathesis from 4-Allyloxy-1H-pyrazoles.
Synthesis of novel pyrazole-fused heterocycles, i.e., dihydro-1H- or 2H-oxepino[3,2-c]pyrazoles (6 or 7) from 4-allyloxy-1H-pyrazoles (1) via combination of Claisen rearrangement and ring-closing metathesis (RCM) has been achieved. A suitable catalyst for the RCM of 5-allyl-4-allyloxy-1H-pyrazoles (4) was proved to be the Grubbs second generation catalyst (Grubbs2nd) to give the predicted RCM p...
