Morpholinium hydrogen Sulphate as Brønsted acidic ionic liquid was used as an efficient and reusable catalyst for the onepot synthesis of 2,4,5-trisubstituted imidazoles that achieved by three component cyclocondensation of 1,2-dicarbonyl compound, aromatic or aliphatic aldehyde and ammonium acetate under thermal solvent-free conditions. The key advantages(More)
A simple highly versatile and efficient synthesis of 2,4,5-trisubstituted imidazoles is achieved by three component cyclocondensation of 1,2-dicarbonyl compounds, aldehydes and ammonium acetate as ammonia source in thermal solvent free condition using Brønsted acidic ionic liquid diethyl ammonium hydrogen phosphate as catalyst. The key advantages of this(More)
A novel series of pyrazoles containing benzenesulfonamides, 1,3,4-oxadiazole-2-thiones, 4-substituted-1,2,4-triazole-3-thiones, and 2-substituted-1,3,4-thiadiazoles has been synthesized. Anti-inflammatory activity of some synthesized compounds was evaluated in vivo utilizing a standard acute carrageenan-induced paw edema method. The most active(More)
The title compound, C26H25BrN2, is isomorphous with the chloro derivative [2-(4-chloro-phen-yl)-1-pentyl-4,5-diphenyl-1H-imidazole; Mohamed et al. (2013 ▶). Acta Cryst. E69, o846-o847]. The two phenyl rings and the 4-bromo-phenyl ring are oriented at dihedral angles of 30.1 (2), 64.3 (3) and 42.0 (2)°, respectively, with respect to the imidazole ring. In(More)
Here we report the first encapsulation of three carbamylated amylose namely R-, S- and R/S-amylose 2,3(3,5-dimethylphenylcarbamate)-6-ethylphenylcarbamate in organic polymer monolith in situ capillary columns. The columns were investigated for the enantioselective nano-liquid chromatographic separation of a set of racemic pharmaceuticals, namely, α- and(More)
The title compound, C24H21ClN2O, crystallizes with two unique mol-ecules in the asymmetric unit. In each mol-ecule, the central imidazole ring is substituted at the 2-, 4- and 5-positions by benzene rings. The 2-substituted ring carries a Cl atom at the 4-position. One of the imidazole N atoms in each mol-ecule has a propan-2-ol substituent. In the crystal,(More)
The asymmetric unit of the title compound, C34H16O5, contains two independent mol-ecules (A and B) with similar conformations. The two benzene rings attached to the nine-membered ring are inclined to one another at 63.62 (14)° in mol-ecule A and 68.23 (12)° in mol-ecule B. One intra-moleculer C-H⋯O hydrogen bond occurs in mol-ecule A and two are observed in(More)
The asymmetric unit of the title compound, C(25)H(22)N(2)O, contains two independent mol-ecules (A and B), with significantly different conformations. In mol-ecule A, the central imidazole ring makes dihedral angles of 88.26 (10) and 12.74 (11)° with the two phenyl rings, and 22.06 (9)° with the benzene ring. In mol-ecule B, one of the phenyl rings is(More)
The central imidazole ring in the title compound, C28H30N2O2, makes dihedral angles of 28.42 (13), 71.22 (15) and 29.50 (14)°, respectively, with the phenyl rings in the 4- and 5-positions and the 3,4-di-meth-oxy-phenyl group. In the crystal, mol-ecules are linked by C-H⋯O and C-H⋯N hydrogen bonds, weak π-π stacking inter-actions [centroid-centroid distance(More)
The title compound, C24H19ClN2, crystallizes with two independent mol-ecules in the asymmetric unit. The prop-2-enyl substituents on the imidazole rings adopt similar conformations in the two mol-ecules. The 4-and 5-substituted phenyl rings and the benzene ring make dihedral angles of 67.06 (8), 5.61 (8) and 41.09 (8)°, respectively, with the imadazole ring(More)
