Interaction of 2 chloro pyrimidines with various substituted thioureas such as thiourea, N- phenylthiourea, 1,3 Dimethylthiourea, N- allylthiourea and ethyl thiourea were carried in presence of isopropanol as a medium. The product isolated in these reactions were characterized on the basis of elemental analysis, chemical characteristics and spectral studies.

Abstract:

Derivatives of piperidinylethyl, phenoxyethyl and fluoroethyl bromopyridyl thioureas were designed and synthesized as non-nucleoside reverse transcriptase inhibitors (NNRTIs) of HIV-1 reverse transcriptase (RT).

Benzothiazole derivatives are a class of privileged molecules due to their biological activity and pharmaceutical applications.

Herein, the copper(II)- and gold(III)-mediated cyclizations of thioureas to substituted 2-aminobenzothiazoles are reported.

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:

4-Thiazolidinones have been prepared by the reaction of various substituted Schiff bases 3 with Thioglycolic acid and Thiolactic acid. The intermediate Schiff bases 3 were synthesized by the condensation of various substituted 2-amino benzothiazole 1 with 1-(4'-methyl Phenyl)-3-methyl-5-pyrazolone 2. The starting compound substituted 2-amino benzothiazoles were prepared from various substituted amines via substituted phenyl thiourea. The structures of the compounds have been confirmed by elemental analysis and spectral analysis. The antibacterial activity of the compounds has also been screene

Abstract:

The cycloaddition reaction of 7-substituted 5H-benzocycloheptenes with singlet oxygen and the chemistry of the obtained endoperoxides were investigated. Reaction of carboethoxy-substituted endoperoxide with NEt3 gave a mixture of products; hydroxyketone, diketone, and carboethoxy-substituted ketoenol tautomers, whereas the reaction of methyl-substituted endoperoxide only formed a diketone under the same reaction conditions. Thermolysis, thiourea, and CoTPP reactions of the endoperoxides were also studied. The reaction mechanism and electronic effect of substituents were discussed.Key words: b

Abstract:

Supramolecular polymers are linear chains of low molar mass monomers held together by reversible and directional non-covalent interactions, which can form gels or highly viscous solutions if the self-assembled chains are sufficiently long and rigid. The viscosity of these solutions can be controlled by adding monofunctional compounds, which interact with the chain extremities: chain stoppers. We have synthesized new substituted ureas and thioureas and tested them as chain stoppers for a bis-urea based supramolecular polymer. In particular, the bis-thiourea analogue of the bis-urea monomer is s

Structures of title compounds were elucidated by their IR, 1H NMR spectral data, molecular weight determination, and microanalyses. Antimicrobial activities against gram-positive and gram-negative bacteria were evaluated by the Filter Paper Disc Method.

Abstract The objective of this study was to synthesize some novel substituted 4-(2-methoxynaphthalen-6-yl) pyrimidine- 2(1H)-thione compounds using sodium hydroxide catalyzed three component condensation and cyclization reaction of substituted 6-methoxy-2-acetonapthone, various substituted benzaldehydes and thiourea. These thione derivatives were characterized by their analytical, physical, and spectroscopic data. In addition, the in vitro antibacterial activities of these pyrimidine derivatives were evaluated using Bauer-Kirby disc diffusion method.

Abstract:

The disubstituted thiourea compounds have shown its reliability on their usages in various industries compared to the thiourea compounds. However, they also show capability to exist in different configurations, which would render them to possess different properties and hence affect their usability by unsuspected users. In this study, investigation was carried out on the polymorphism of five disubstituted thiourea compounds in which the phenyl rings and arylhalide acted as substituents.
