Abstract:
In the title pyrazolone derivative, C15H12N2O, the five-membered ring is approximately planar (r.m.s. deviation = 0.018 Å), and the N- and C-bound benzene rings are inclined to this plane [dihedral angles = 21.45 (10) and 6.96 (10)°, respectively] and form a dihedral angle of 20.42 (10)° with each other. Supramolecular layers are formed in the crystal structureviaC—H...O and C—H...N interactions, and these are assembled into double layers by C—H...π and π–π interactions between the pyrazole and C-bound benzene rings [ring centroid–centroid distance = 3.6476 (12) Å]. The double layers stack alo

Abstract:
In this paper, an efficient synthetic route from pyrazole-chalcones to novel 6-aryl-5-hydroxy-2-phenylpyrano[2,3-c]pyrazol-4(2H)-ones as 3-hydroxyflavone analogues is described. The methylation of 5-hydroxy-2,6-phenylpyrano[2,3-c]pyrazol-4(2H)-one with methyl iodide in the presence of a base yielded a compound containing a 5-methoxy group, while the analogous reaction of 5-hydroxy-2-phenyl-6-(pyridin-4-yl)pyrano[2,3-c]pyrazol-4(2H)-one led to the zwitterionic 6-(N-methylpyridinium)pyrano[2,3-c]pyrazol derivative.

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%.
