Soil-borne plant pathogens such as nematodes, fungi and some bacteria not only affect the plant cultures but also economy and environmental implications. As a result of these pathogens attacks, the yield and quality of crops is affected. Therefore, synthesis of new compounds to control these pat...
An irrefutable advancement has been noted for the infectious diseases caused due to ureolytic bacteria through the development of various drugs. Keeping in mind the extremely valuable synthetic utility and medicinal significance of thiourea derivatives, synthesis of new 3-trifluoromethyl benzoic...
Trifluoromethyl carbanions generated from the Ruppert reagent and TASF add to highly electron-deficient nitroarenes to produce σH adducts subsequently oxidized with dimethyldioxirane to substituted trifluoromethyl phenols.
The synthesis of the trifluoromethyl group containing enol ethers by the palladium-catalyzed intermolecular reaction of 2,3,3-trifluoroallylic carbonates with oxygen nucleophiles was accomplished. The reaction proceeds through the intermolecular attack of oxygen nucleophiles on the C-2 carbon at...
Ab initio conformers and dimers have been computed at RHF and B3LYP/6-31G* levels for isomers 2-chloro-3-hydroxybenzaldehyde and 3-chloro-4-hydroxybenzaldehyde to explain the observed infrared absorption and Raman vibrational spectral features in the region 3500–50 cm−1. The position of the chl...
Substituted α,α-bis(trifluoromethyl)salicylic alcohols react with dichlorido(thio)phosphates in the presence of NEt3 to afford 2-alkoxy-4,4-bis(trifluoromethyl)-4H-1,3,2-benzodioxaphosphinine 2-oxide(sulfides) in high yields. The latter can be of interest as potential cholinesterase inhibitors.
The first representatives of 3-trifluoromethyl-2-(dialkoxyphosphoryl)imidazo[1,2-a]pyridines have been synthesized by the reaction of N-(pyridin-2-yl)-perfluoropropanimidoyl chlorides with triethyl phosphite.
A one-pot multigram synthesis of 3-(trifluoromethyl)-1H-pyrazolo[3,4-b]pyridine starting from 2-fluoropyridine using directed ortho metallation (DoM) technique is described. The compound contains an anionically activatable trifluoromethyl group and is a versatile building block for the microwave...
5-Alkyl-4-amino-2-(trifluoromethyl)pyridines were prepared in good yields starting from the corresponding pyridinols either using condensation with tosyl isocyanate or by alkylation with 2-chloroacetamide and subsequent Smiles type rearrangement. The cyclisation of diazonium salts, generated fro...
Reactions of perfluoro-2-methylpent-2-ena or perfluoro-5-azanon-4-ene with a range of bidentate nitrogen nucleophiles (urea, acet-, benz-, 4-nitrobenz-amidine hydrochloride, 2-aminopyridine, 2-aminobenzimidazole, guanidine) in the presence of Et3N or KOH effectively provided partially fluorinate...
The reaction of α-halosubstituted β-ethoxyvinyl trifluoromethyl ketones with 2-aminopyridine gives 3-trifluoroacetyl imidazo[1,2-a]pyridine and 3-halo-1,1,1-trifluoro-4-(2-pyridinylamino)-3-buten-2-ones. The product ratio depends on the nature of the α-halogen atom and the solvent.
A convenient synthesis of N,N-bis(trifluoromethyl)anilines by means of dediazotation reactions of previously unknown aryldiazoniumbis(trifluoromethyl)imides in the presence of CuI salts are described. Properties and applications of N,N-bis(trifluoromethyl)anilines in syntheses of aromatic compou...
The FTIR and FT-Raman spectra of 2-(trifluoromethyl)aniline (2TFMA) and 3-(trifluoromethyl)aniline (3TFMA) have been recorded in the range 4000–400 and 4000–100 cm−1, respectively. The experimental vibrational frequencies were assigned and interpreted satisfactorily. The interpretation relies ...
The solubility of 2-chloro-3-(trifluoromethyl)pyridine was measured at 273.15 K–303.15 K under atmospheric pressure in methylbenzene, dichloromethane, ethanol, n-propanol, n-hexane, n-heptane and ethanol + 1-propanol binary solvents. The solubility of 2-chloro-3-(trifluoromethyl)pyridine in pur...
BackgroundGastric bypass surgery for weight reduction often corrects dysglycemia in diabetic patients, but a full understanding of the underlying biochemical pathways continues to be investigated.
Lithocholic acid (2) was identified as the second endogenous ligand of vitamin D receptor (VDR), though its binding affinity to VDR and its vitamin D activity are very weak compared to those of the active metabolite of vitamin D3, 1α,25-dihydroxyvitamin D3 (1). 3-Acylated lithocholic acids were...
(RS)-2-Amino-3-(3-carboxy-5-methyl-4-isoxazolyl)propionic acid (ACPA), which is a potent and selective agonist at (RS)-2-amino-3-(3-hydroxy-5-methyl-4-isoxazolyl)propionic acid (AMPA) receptors, has previously been shown to desensitize AMPA receptors to a much lower degree than AMPA itself. We n...
Vanadyl proline [VO(Hpro)(SO4)(H2O)3] (1, Hpro = proline), lysine trans-[VO(H2lys)2(H2O)3]Cl4·H2O (2, Hlys = lysine) and histidine [VO(H2his)(2,2′-bipy)(H2O)2]Cl3·H2O (3, Hhis = histidine) have been obtained in acidic conditions. Proline, lysine and histidine in 1–3 feature monodentate coord...
A tri-functional polyhedral oligomeric silsesquioxane (POSS) based silane precursor RxRyRz(SiO3/2)n (x + y + z = n = 6, 8, 10, ….) bearing 3-(N-(3-triethoxysilylpropyl)ureido)propyl, isooctyl and perfluoropropyl groups was synthesized and investigated as corrosion protective coating for AA 2024...
