Cyclometalation on the substituted imidazo[1,2-a][1,8]naphthyridine platform involves either the C-3-aryl or C-4′-aryl ortho carbon and the imidazo nitrogen N-3′. The higher donor strength of the imidazo nitrogen in comparison to that of the naphthyridine nitrogen aids regioselective orthometalation at the C-3/C-4′-aryl ring with Cp*Ir-III (Cp* = eta(5)-pentamethylcyclopentadienyl). A longer reaction time led to double cyclometalations at C-3-aryl and imidazo C-5′-H, creating six- and five-membered metallacycles on a single skeleton. Mixed-metal Ir/Sn compounds are accessed by insertion of SnCl2 into the Ir-Cl bond. Pd(OAc)(2) afforded an acetate-bridged dinuclear ortho-metalated product involving the C-3-aryl unit. Metalation at the imidazo carbon (C-5′) was achieved via an oxidative route in the reaction of the bromo derivative with the Pd(0) precursor Pd-2(dba)(3) (dba = dibenzylideneacetone). Regioselective C-H/Br activation on a rigid and planar imidazonaphthyridine platform is described in this work.

The inhibition effect of three naphthyridine derivatives namely 2-amino-4-(4-methoxypheny1)-1,8-naphthyridine-3-carbonitrile (ANC-1), 2-amino-4-(4-methylpheny1)-1,8-naphthyridine-3-carbonitrile (ANC-2) and 2-amino-4-(3-nitrophenyI)-1,8-naphthyridine-3-carbonitrile (ANC-3) as corrosion inhibitors for N80 steel in 15% HCl by using gravimetric, electrochemical techniques (EIS and potentiodynamic polarization), SEM, EDX and quantum chemical calculation. The order of inhibition efficiency is ANC-1 > ANC-2 > ANC-3. Potentiodynamic polarization reveals that these inhibitors are mixed type with predominant cathodic control. Studied inhibitors obey the Langmuir adsorption isotherm. The quantum calculation is in good agreement with experimental results. (C) 2015 Elsevier B.V. All rights reserved.

Several 2-amino-6-aryl-1,8-naphthyridines were reported. The cyclocondensation of 2,6-diaminopyridine, 2-bromomalonaldehyde in phosphoric acid resulted in the formation of 2-amino-6-bromo-1,8-naphthyridine, which was converted into 2-amino-6-aryl-1,8-naphthyridines by palladium-catalyzed Suzuki reaction with arylboronic acid. It is shown that the Suzuki coupling with palladium catalyst (Pd-132) could be completed efficiently with lower catalyst loading and good to excellent yields. The title compounds were characterized by NMR spectra and mass spectra.

GlaxoSmithKline and Astex Pharmaceuticals recently disclosed the discovery of the potent H-PGDS inhibitor GSK2894631A la (IC50 = 9.9 nM) as part of a fragment-based drug discovery collaboration with Astex Pharmaceuticals. This molecule exhibited good murine pharmacokinetics, allowing it to be utilized to explore H-PGDS pharmacology in vivo. Yet, with prolonged dosing at higher concentrations, la induced CNS toxicity. Looking to attenuate brain penetration in this series, aza-quinolines, were prepared with the intent of increasing polar surface area. Nitrogen substitutions at the 6- and 8-positions of the quinoline were discovered to be tolerated by the enzyme. Subsequent structure activity studies in these aza-quinoline scaffolds led to the identification of 1,8-naphthyridine 1y (IC50 = 9.4 nM) as a potent peripherally restricted H-PGDS inhibitor. Compound 1y is efficacious in four in vivo inflammatory models and exhibits no CNS toxicity.

Aerial oxidation of the quadruply bonded Mo-2(OAc)(4) in the presence of HprNP (2-(2-pyrrolyl)-1,8-naphthyridine) in CH2Cl2 provide the dinuclear oxochloromolybdate [Mo2O2Cl2(mu(2)-O)(2)(HprNP)(2)] (1). The molecular structure of 1 consists of the [Mo2O2Cl2(mu(2)-O)(2)] core with the cisoid Mo=O bonds and each HprNP ligand chelating the Mo center through the naphthyridine unit. An alternate route to access oxomolybdates is to employ quadruply bonded [Re2Cl8](2-) to oxidize cis-[Mo-2(pyNP)(2)(OAC)(2)][BF4](2) (pyNP = 2-(2-pyridyl)1,8-naphthyridine). The isolated compound is the tetranuclear molybdenum cluster [Mo4Cl5O8(pyNP)(2)] (2). The molecular formula of compound 2 is best described as [Mo2Cl3O2(mu(2)-O)(eta(3)-pyNP)][mu(3)-O][Mo2Cl2O2(mu(2)-O)(2)(eta(2) -pyNP)], the fusion of two oxochlorodimolybdates linked through a mu(3)-oxo linkage. The oxidation of the [Mo-coproduct equivalent to Mo-coproduct] unit to highly oxidized oxomolybdates and subsequent dimerization to tetranuclear core offers prospect for accessing new types of oxo-chloro-molybdenum clusters exhibiting interesting structural motifs.

Two stereoisomers of cis-[Ru(bpy)(pynp)(CO)Cl]PF(6) (bpy = 2,2′-bipyridine, pynp 2-(2-pyridyl)-1,8-naphthyridine) were selectively prepared. The pyridyl rings of the pynp ligand in [Ru(bpy)(pynp)(CO) Cl](+) are situated trans and cis, respectively, to the CO ligand. The corresponding CH(3)CN complex ([Ru(bpy)(pynp)(CO) (CH(3)CN)](2+)) was also prepared by replacement reactions of the chlorido ligand in CH(3)CN. Using these complexes, ligand-centered redox behavior was studied by electrochemical and spectroelectrochemical techniques.

Arsenic ion is a well-known harmful heavy element widely existing in the environment. Arsenic pollution occurring frequently has become increasing a serious worldwide threat to human health and the environment. The development of sensitive and reliable methods to detect As3+ in water is of great importance to biochemical research and monitoring applications. Herein, a label-free fluorescence sensing platform was elaborately designed for As3+ monitoring using exonuclease III (Exo III)-assisted cascade target recycling amplification strategy. The triple-helix molecular switch was employed as the sensing element and 2-amino-5,6,7-trimethyl-1,8-naphthyridine was used as the signal indicator. The resulting biosensor is simple, ultrasensitive, and exhibits a limit of detection of 5 ng/L with high selectivity. Meanwhile, the proposed sensor is successfully applied to determination of As3+ in practical sample analysis (tap water, lake water and pond water). The results shown herein have important implications in the development of new fluorescent sensors for the fast, easy, and selective detection and quantification of As in water samples. More importantly, the proposed platform can be extended to detect other heavy metal ions with newly designed triple-helix molecular switch, as well as pesticide residue, antibiotic residues, and biomarkers by using aptamer sequences.

Chemical Research Letters, May 2021. Catalysts allow a reaction to proceed via a pathway that has a lower activation energy than the uncatalyzed reaction. catalysts provide a surface to which reactants bind. In an article, author is Nammalwar, Baskar, once mentioned the application of 6165-69-1, Name is 3-Thiopheneboronic acid. Now introduce a scientific discovery about this category, Quality Control of 3-Thiopheneboronic acid.

One-step syntheses of 2-alkyl- and 2,4-dialkyl-substituted quinoline-3-carboxylic acids and 1,8-naphthyridine-3-carboxylic acids are reported using a catalyst-free Friedlander reaction. The reaction is carried out in one step by simple heating of 2-aminobenzaldehyde, 2-amino-5-chlorobenzaldehyde, 2-aminonicotinaldehyde, or 2-aminoacetophenone with a beta-ketoester in toluene or xylene for 24 h. Under these conditions, the carboxylic acid product is isolated directly from the reaction mixture without need for further purification. The observation that the reaction starts slowly and accelerates as it proceeds suggests that the transformation is self-catalyzed. This hypothesis is also supported by the finding that attempts to extend the current reaction to diketones, which cannot hydrolyze to an acid, were generally unsuccessful. (C) 2014 Elsevier Ltd.
