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 کاملSynthesis of 4- and 5- nitro-substituted heteroaryl cinnamoyl derivatives
In the condensation of the 4and 5-nitro-substituted 2-acetyl-1,3-indandione with heteroaryl aldehydes in the presence of alkaline or acidic catalysts, the corresponding cinnamoyl derivatives are obtained that possess anticoagulant activity, compared with that of 2-acetyl-1,3-indandione. It has been proven that some of the sodium salts of the cinnamoyl-indandione possess anticoagulant activity. ...
متن کاملThe Synthesis and Molecular Structure of 2-(4-Methoxybenzyl)-4-nitro-2H-indazole
Two novel indazole derivatives protected with p-methoxybenzyl group were synthesized and characterized. The crystal and molecular structure of 2-(4-methoxybenzyl)-4-nitro-2H-indazole as one out of the two regioisomers is reported. The compound was obtained from a saturated petroleum ether/ethyl acetate mixture and crystallizes in the triclinic space group P1. The unit cell parameters are: a = ...
متن کامل4-Nitro-N-(4-nitrobenzoyl)benzamide
The central acetyl-acetamide moiety in the title compound, C(14)H(9)N(3)O(6), is buckled [e.g. the C-N-C-O torsion angle is 14.3 (6)°] but the r.m.s. deviation for the five atoms is 0.044 Å. The benzene rings lie on the same side of the central plane, forming dihedral angles of 37.17 (15) and 28.58 (19)° with it. The dihedral angle between the two rings is 17.8 (2)° indicating that the mol-ecul...
متن کامل4-Methoxy-2-nitro-4′-(trifluoromethyl)biphenyl
The title compound, C(14)H(10)F(3)NO(3), was prepared by a palladium-catalysed Suzuki-Miyaura coupling reaction. The dihedral angle between the nitro group and its parent benzene ring is 66.85 (19)° while the dihedral angle between the two benzene rings is 49.98 (9)°. The CF(3) group is disordered over two sets of sites with occupancies of 0.457 (8) and 0.543 (8).
