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 کاملMethyl 2-acetamido-2-(4-hydroxy-2-methyl-1,3-dioxo-1,2,3,4-tetrahydroisoquinolin-4-yl)-4-methylpentanoate
In the isoquinoline ring system of the title mol-ecule, C(19)H(24)N(2)O(6), the N-heterocyclic ring is in a half-boat conformation. The mol-ecular structure is stabilized by an intra-molecular O-H⋯O hydrogen bond, which generates an S(7) ring motif. In the crystal, mol-ecules are linked via inter-molecular bifurcated N-H⋯(O,O) and weak C-H⋯O hydrogen bonds into a three-dimensional network.
متن کاملBut-2-enal 2,4-dinitrophenylhydrazone
In the title compound, C(10)H(10)N(4)O(4), the but-2-enal chain is almost planar, the largest deviation from the mean plane being 0.013 (1) Å, and this plane makes a dihedral angle of 9.95 (24)° with the benzene ring,. Of the two nitro groups, one is twisted with respect to the benzene ring, making a dihedral angle of 5.7 (1)°, whereas the other is nearly in the plane of the benzene ring, with ...
متن کامل2-Methyl-4-nitrophenol
The mol-ecule of the title compound, C(7)H(7)NO(3), is nearly planar [maximum deviation 0.112 (3) Å for one of the notro O atoms]. In the crystal structure, inter-molecular O-H⋯O and C-H⋯O inter-actions link the mol-ecules into a three-dimensional network.
متن کامل2, 4-Dihydroxy-5-Bromo [2’Methyl] Propiophenone Thiosemicarbazone [DHBMPT] as an Analytical Reagent: Studies on Pd (II) Chelate
2, 4-Dihydroxy-5-Bromo-[2’methyl]-Propiophenone thiosemicarbazone [DHBMPT] has been used for the spectrophotometric determination of Pd(II) at pH = 2.5. Job’s method of continuous variation and Yoe and Jones Mole ratio method show metal: ligand ratio in the complex to be 1:1. The molar absorptivity of complex at 390 nm was found to be 1.457 x10 lit.mol.cm and Sandell’s sensitivity was found to ...
