Abstract:

In this study, hexasubstituted thiourea was carried out via reaction of isothiocyanato cyclophosphazene intermediates with a series of aromatics amines and amino acids in a one-pot reaction system. The reaction was not as straightforward as typical thiourea synthesis. Six unexpected thiourea derivatives3a–fwere formed in the presence of cyclotriphosphazene moieties in good yields (53–82%). The structures of3a–fwere characterized by elemental analysis and FTIR,1H,13C, and31P NMR spectroscopies. The occurrence of reverse thioureas formation in a one-pot reaction system is discussed.

Abstract:

Environmental pollution with chiral organic compounds is an emerging problem requiring innovative sensing methods. Amino-functionalized thioureas, such as 2-(dimethylamino)cyclohexyl-(3,5-bis(trifluoromethyl)phenyl)thiourea (Takemoto’s catalyst), are widely used organocatalysts with virtually unknown environmental safety data. Ecotoxicity studies based on the Vibrio fischeri luminescence inhibition test reveal significant toxicity of Takemoto’s catalyst (EC50 = 7.9 mg/L) and its NH2-substituted analog (EC50 = 7.2–7.4 mg/L). The observed toxic effect was pronounced by the influence of the trifl

The proposed mechanism indicates that the regioselective formation of the target thiazolidinones is a consequence of a different reactivity of the reagents and a varying stability of the intermediates, 1-alkyl-3-(anthracen-9-yl)-2-[(methoxycarbonyl)methyl]isothioureas 4a-

The reactivity lowering of the N'-monosubstituted thioureas is ascribed to the intramolecular hydrogen bond C=O...H-N due to which these compounds in their ground states exist in the six-membered cyclic conformation unfavourable for the cyclization.

A series of thiourea ligand , N-N'- diphenyl thiourea [I] [DPTH], N-phenyl-N'-[2-phenoyl] thiourea [II] [PPTH], N-phenyl-N'-[2-chlorophenyl] thiourea III [PCPTH], N-phenyl-N'- [5-chloro-2-methyl phenyl] thiourea IV [PCMPTH] and N- phenyl -N'-(5-chloro-2-methoxy phenyl) thiourea V (PCMTPTH) and their transition metal complexes of the type ML2 and ML2 Cl2 have been synthesized by reacting phenyl isothiocyanate with substituted aniline and transition metal salts. These newly synthesized ligands and their complexes were characterized by elemental and spectral studies. Based upon these studies it w

Abstract:

Kinetics of nucleophilic addition reaction of 9-isothiocyanatoacridine with seventeen aliphatic and aromatic amines in organic solvents has been studied by the VIS spectroscopic method. 9-Isothiocyanatoacridine reacted by about two orders of magnitude faster than phenyl isothiocyanate. The reaction rates of aliphatic amines were markedly affected by steric effects. Excepting 1-acridin-9-yl-3-butylthiourea (IIIo), the products obtained exhibited weaker fluorescence than the starting 9-isothiocyanatoacridine.

Abstract:

Background: Urease enzyme catalyzes the hydrolysis of urea into ammonia and CO2, excess ammonia causes global warming and crop reduction. Ureases are also responsible for certain human diseases such as stomach cancer, peptic ulceration, pyelonephritis, and kidney stones. New urease inhibitors are developed to get rid of such problems. Objective: This article describes the synthesis of a series of novel 1-aroyl-3-(2-oxo-2H-chromen-4- yl)thiourea derivatives (5a-j) as Jack bean urease inhibitors. Methods: Freshly prepared aryl isothiocyanates were reacted with 4-aminocoumarin in the same pot in

Abstract:

A series of some novel 2,4-diaryl-3,5-bis(arylimino)-1,2,4-thiadiazolidine derivatives were synthesized and evaluated for anti-inflammatory activity. In the SAR study, the phenyl ring on 3 and 4 position of 1,2,4-thiadiazolidine ring substituted with chloro, nitro and methoxy groups showed better activity. The title compounds were synthesized from two steps; the first step involved the synthesis of diaryl substituted thioureas then, it was cyclised to give the 1,2,4-thiadiazole system in the presence of oxidizing agent (hydrogen peroxide and concentrated hydrochloric acid) in the second step.
