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 compounds were evaluated for their in vitro antibacterial antifungal and antioxidant activities. In vitro antimicrobial evaluation of these compounds indicated their specificity towards Gram-positive species. p-Tolyl and m-chlorophenyl substituents on the arylamino moiety (compounds 4b and 4g) exhibited the lowest minimum inhibitory concentrati

A regioselective synthesis of 3-alkyl-2-[(anthracen-9-yl)imino]thiazolidin-4-ones 2a-2e and 2-(alkylimino)-3-(anthracen-9-yl)thiazolidin-4-ones 3a-3e from appropriate thioureas using methyl bromoacetate or bromoacetyl bromide, respectively, has been rationalized by DFT calculations of model thiourea and its phenyl derivative. 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-

Abstract:
N-(3-Chloro-2-benzo[b]thienocarbonyl)-N'-monosubstituted thioureas, when irradiated with a high-pressure mercury discharge lamp through a pyrex or quartz filter, give the corresponding benzothienothiazine derivatives in lower yields than the analogous N',N'-disubstituted thioureas. 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.

New derivatives of the quinolizidine alkaloid, (–)-cytisine, with a substituted 2-pyridone ring and a thiourea moiety in the bispidin fragment of the molecule were synthesized. The ability of the synthesized cytisine-containing thioureas to inhibit the reproduction of human parainfluenza virus type 3 was assessed. It was found that the derivatives obtained by the reaction of benzoyl or phenyl isothiocyanate with (–)-cytisine, as well as its 9-bromo or 9,11-derivative, effectively suppress the reproduction of human parainfluenza virus type 3 (their selectivity indices are 56, 58 and 95, respect

Abstract The application of acid corrosion inhibitors is an absolute necessity to prevent damage to process equipment during acid cleaning operations. The use of organic acids and mineral acids that are not HCl has expanded because of environmental concerns and issues of compatibility with alloys such as stainless or duplex steel. Inhibitors which are used to protect the metals from corrosion by organic acids often contain a number of highly toxic compounds based on amine technology such as quaternary amines, amine ethoxylates, imidazolines and polyamides as well as sulfur compounds such as th
