PYRAZOLINES AND ISOXAZOLINES (I). SYNTHESIS AND ANTIMICROBIAL ACTIVITIES OF P-(1-ACYL-3-METHYL-5-ARYL-4 PYRAZOLINOYL / P-(3-METHYL-5-ARYL-4ISOXAZOLINOYL) ARSANILIC ACID
4-(acetoacetamido) arsanilic acid (II), which was then condensed with aryl aldehydes. The resulting product on reaction with hydrazine hydrate and hydroxyl amine hydrochloride yielded Pyrazolines (IV) and Isoxazolines (V), respectively. The antimicrobial activity of compounds against a number of microorganisms was evaluated. Some of these compounds showed significant antimicrobial activity
متن کامل5-Methyl-3-phenylisoxazole-4-carboxylic acid
In the title compound, C11H9NO3, the phenyl and isoxazole rings form a dihedral angle of 56.64 (8)°. The carb-oxy group is almost in the same plane as the isoxazole ring with a C-C-C-O torsion angle of -3.3 (2)°. In the crystal, pairs of O-H⋯O hydrogen bonds link the mol-ecules into head-to-head dimers. C-H⋯N hydrogen bonds and π-π stacking inter-actions between phenyl rings [centroid-centroid ...
متن کامل5-Methyl-1,2-oxazole-3-carboxylic acid
In the crystal structure of the title compound, C(5)H(5)NO(3), all the non-H atoms are approximately coplanar: the carb-oxy O atoms deviating by 0.013 (2) and -0.075 (2) Å from the isoxazole ring plane. In the crystal, the molecules form inversion dimers linked by pairs of O-H⋯O hydrogen bonds and the dimers stack via π-π inter-actions [centroid-centroid distance = 3.234 (2) Å].

متن کامل1-Methyl-1H-indazole-3-carboxylic acid
The asymmetric unit of the title compound, C(9)H(8)N(2)O(2), contains two mol-ecules. In the crystal structure, both mol-ecules form inversion dimers via pairs of O-H⋯O hydrogen bonds, and a C-H⋯O inter-ation is also seen.
