Abstract:

By the reaction of benzoyl chloride, potassium isothiocyanate and the appropriate halogenoaniline, i.e. 2/3/4-(bromo/iodo)aniline, we have obtained five new 1-benzoyl-3-(halogenophenyl)thioureas, namely, 1-benzoyl-3-(2-bromophenyl)thiourea and 1-benzoyl-3-(3-bromophenyl)thiourea, C14H11BrN2OS, and 1-benzoyl-3-(2-iodophenyl)thiourea, 1-benzoyl-3-(3-iodophenyl)thiourea and 1-benzoyl-3-(4-iodophenyl)thiourea, C14H11IN2OS. Structural and conformational features of the compounds have been analyzed using X-ray diffraction and theoretical calculations. The novel compounds were characterized by solid-

Abstract:

A series of novel thiourea and amide liquid crystals containing 5-membered isoxazoline and isoxazole rings were synthetized and the liquid crystal properties studied. Thioureas were obtained using a condensation reaction of benzoyl chlorides, arylamines and ammonium thiocyanate. The amides, on the other hand, were the byproduct of a quantitative reaction which used potassium cyanate as the starting material. Thiourea and amide derivatives were predominantly SmA mesophase inductors. A nematic mesophase was observed only for thioureas and amides containing an isoxazole ring. Additionaly, the liq

Abstract:

The molecular structure of the title compound, C14H13N3OS, adopts a cis–trans configuration with respect to the positions of the benzoyl and 6-methylpyridin-2yl groups relative to the S atom across the thiourea C—N bonds. In the crystal structure, the molecules are linked by N—H...S, C—H...S and C—H...O interactions, forming a one-dimensional chain parallel to the b axis.

Abstract:

The article presents data on the synthesis and study of the structure of thiourea derivatives of functionally substituted pyridines. New thiourea derivatives containing a pharmacologically active pyridine moiety in their structure were obtained. As the starting synton, 2-amino-5-bromopyridine, 2-amino-3-hydroxypyridine and 2-aminomethylpyridine were selected. It was shown that the interaction of 2-amino-5-bromopyridine, 2-amino-3-hydroxypyridine and 2-aminomethylpyridine with ethyl and phenylisothiocyanates in ethanol leads to the formation of the corresponding pyridine-containing thioureas.

Abstract:

Intramolecular hydrogen bonds of the N-H···O=C type have been detected in the derivatives of N-substituted N’-benzoyl- and N’-(2-chlorobenzoyl)thiourea on the basis of IR spectral studies. The title compounds can exist in two tautomeric forms.

Abstract:

The title compound, C14H11FN2OS, contains two molecules (AandB) in the asymmetric unit, with different conformations. In moleculeA, the dihedral angles between the central thiourea grouping and the phenyl and fluorobenzene rings are 28.77 (8) and 41.82 (8)°, respectively, and the dihedral angle between the ring planes is 70.02 (9)°. Equivalent data for moleculeBare 8.46 (8), 47.78 (8) and 52.99 (9)°, respectively. Both molecules feature an intramolecular N—H...O hydrogen bond, which closes anS(6) ring. In the crystal,A+Bdimers linked by pairs of N—H...S hydrogen bonds generateR22(8) loops.

Abstract:

1-Benzoylthioureas contain both carbonyl and thiocarbonyl functional groups and are of interest for their biological activity, metal coordination ability and involvement in hydrogen-bond formation. Two novel 1-benzoylthiourea derivatives, namely 1-benzoyl-3-(3,4-dimethoxyphenyl)thiourea, C16H16N2O3S, (I), and 1-benzoyl-3-(2-hydroxypropyl)thiourea, C11H14N2O2S, (II), have been synthesized and characterized. Compound (I) crystallizes in the space group P\overline{1}, while (II) crystallizes in the space group P21/c. In both structures, intramolecular N—H...O hydrogen bonding is present. The resu

Abstract:

5-Amino-1-phenylpyrazole-4-carboxamide was condensed with benzoyl isothiocyanate. The resulting thiourea was treated with dicyclohexylcarbodiimide and annulated with ethanolic ammonia to yield 4-amino-1-phenylpyrazolo[3,4-d]pyrimidin-6(5H)-one. This product is a 1-phenylpyrazolo[3,4-d] pyrimidine analogue of the biologically active natural product, isoguanosine.

Abstract:

The reaction mechanism of the title reaction was proposed on the bases of the kinetic study. The reaction takes place in two stages considerably differing in rates. In the first, faster stage, the anion of initial substance cyclizes to 1-methyl-3-benzoyl-2-thioxo-4-quinazolone. The reaction is reversible, the concentration of 1-methyl-3-benzoyl-2-thioxo-4-quinazolone decreases with increasing concentration of methanolate. In the second stage, the benzoyl group rearrangement in the given substance from nitrogen to sulfur and subsequent methanolysis to 1-methyl-2-thioxo-4-quinazolone take place.
