A synthesis of 2-((4-phenyl-5-(2-(p-tolylamino)ethyl)-4H-1,2,4-triazol-3-yl)thio)-N’-(1-phenylethylidene)acetohydrazide from 2-[(3-{2-[(4-methylphenyl)amino]ethyl}-4-phenyl-4,5-dihydro-1H-1,2,4-triazol-5-yl)sulfanyl]acetohydrazide and acetophenone is reported. The title compound has been tested to possess 1.5-fold higher antioxidant ability than the control, butylated hydroxytoluene, as determi...
The new polyheterocyclic compound, 2-benzyl-7-(4-chlorophenyl)-3-morpholino-6-((1-phenyl-1H-1,2,3-triazol-4-yl)methyl)-6,7-dihydro-5H-pyrrolo[3,4-b]pyridin-5-one, was synthesized by a sequential combination of 4-chlorobenzaldehyde, (1-phenyl-1H-1,2,3-triazol-4-yl)methanamine, 2-isocyano-1-morpholino-3-phenylpropan-1-one, and maleic anhydride under microwave-assisted one-pot process [Ugi-Zhu/aza...
Both the acetyl and phenyl substituents of the central pyrazole ring in the title compound, C(24)H(20)N(2)O(3)S, are twisted with respect to the pyrazole ring, with the twist involving the phenyl ring being greater [67.4 (1) and 29.6 (2)°]. The tolyl substituent is disordered over two positions in a 1:1 ratio; the mean planes of the aromatic ring are aligned at 67.7 (3) and 69.4 (3)° with respe...
A number of N-(arylcarbamothioyl)cyclohexanecarboxamide derivatives (aryl substituents: phenyl, 2-chlorophenyl, 3-chlorophenyl, 4-chlorophenyl, o-tolyl, p-tolyl, 3-methoxyphenyl, 4-methoxyphenyl and naphthalen-1yl) have been synthesized. The compounds obtained were characterized by elemental analyses, IR spectroscopy and (1)H-NMR spectroscopy. N-(naphthalen-1-ylcarbamothioyl)cyclohexanecarboxam...
In the title compound, C(16)H(17)N(3)S, the amino-thio-urea unit is nearly planar (r.m.s. deviation = 0.0425 Å), and is twisted with respect to the tolyl and phenyl rings by 57.84 (7) and 15.88 (14)°, respectively; the tolyl and phenyl rings are twisted by 65.64 (11)° to each other. Inter-molecular N-H⋯S and weak C-H⋯S hydrogen bonds are present in the crystal structure.
The title compound, C(15)H(21)N(3)O(3)S, is known to be an impurity of gliclazide [systematic name: N-(hexa-hydro-1H-cyclopenta[c]pyrrol-2-ylcarbamo-yl)-4-methyl-benzene-sulfonamide], a sul-fonyl-urea anti-diabetic drug. Gliclazide has a p-tolyl group substituting the sulfonamide functionality, while the title mol-ecule contains an o-tolyl group. Both five-membered fused rings adopt envelope co...
In the title compound, C(19)H(18)N(2)O(2), the dihedral angle between the mean planes of the fused chromeno and isoxazole units is 43.71 (7)°. The isoxazole and pyran rings exhibit envelope and half chair conformations, respectively. The crystal packing is stabilized by inter-molecular C-H⋯π inter-actions.
