Design and Synthesis of 2-Methyl and 2-Methyl-4-Nitro Imidazole Derivatives as Antifungal Agents
Two series (a and b) of N- substituted heteroaromatic compounds related to clotrimazole were synthesized. Imidazole ring of the clotrimazole was replaced by 2-methylimidazole in series a, and by 2-methyl-4-nitroimidazole in series b. O-cholortrityl moiety of clotrimazole was also replaced by trityl, mono or dimethoxy trityl. Chemical structures...
متن کامل1-(2-Methyl-6-nitro-4-phenyl-3-quinolyl)ethanone
In the title compound, C(18)H(14)N(2)O(3), the quinoline ring system is almost planar [maximum deviation = 0.013 (2) Å] and forms a dihedral angle of 60.36 (7)° with the benzene ring. The nitro group is slightly twisted from the attached quinoline ring system, forming a dihedral angle of 9.06 (19)°. In the crystal packing, inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into chains pro...
متن کاملGreen synthesis and evaluation of 5-(4-aminophenyl)-4-aryl-4H-1, 2, 4-triazole-3-thiol derivatives
The green synthesis of 5-(4-aminophenyl)-4-aryl-4H-1,2,4-triazole-3-thiol was achieved in four steps, In first step, 4-amino benzoic acid refluxed in ethanol along with catalyst Conc. Sulphuric acid to produce ethyl-4-amino benzoate I. Further compound I refluxed with hydrazine hydrate in ethanol to produce 4-amino benzohydrazide II. Compound II refluxed in ethanolic potassium hydroxide with ca...
متن کامل(E)-1-Nitro-4-(2-nitroethenyl)benzene
The asymmetric unit of the title compound, C(8)H(6)N(2)O(4), consists of two independent mol-ecules with similar geometries, each adopting a trans configuration about the olefinic double bond. The two mol-ecules are both almost planar (r.m.s. deviations = 0.034 and 0.035 Å) and form a dihedral angle of 83.62 (2)°. Short N⋯O contacts [2.834 (3)-2.861 (3) Å] are observed between the nitro groups ...
متن کامل2-(4-Methylphenyl)-1-phenylsulfonyl-3-nitro-1,2-dihydroquinoline
In the title compound, C(22)H(18)N(2)O(4)S, the dihedral angle between the phenyl-sulfonyl ring and the methyl-phenyl ring is 67.78 (7)°. In the crystal, mol-ecules are linked by weak inter-molecular C-H⋯O inter-actions into a zigzag chain along the [101] direction.
