An Efficient Strategy for the Synthesis of 1,6-Naphthyridine-2,5-dione Derivatives under Ultrasound Irradiation

A flexible and efficient three-component reaction has been established for the synthesis of bioactive 1,6-naphthyridine-2,5-diones by using low-cost and readily accessible aminopyridinones, aromatic aldehydes, and Meldrum’s acid as starting materials. The main advantage of this synthetic method is that the yields of the resulting 1,6-naphthyridine-2,5-dione derivatives under ultrasound irradiation in water with acetic acid as catalyst are higher than those from the classical-heating method. The probable reaction mechanism indicates that the process involves a Knoevenagel condensation, Michael addition, and cyclization sequence.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 13922-41-3 is helpful to your research. Name: Naphthalen-1-ylboronic acid.

Synthesis and Neurotropic Activity of Triazolo[3,4-a]-and Triazolo[5,1-a][2,7]Naphthyridines

Methods for synthesizing new substituted 7,8,9,10-tetrahydro[1,2,4]triazolo[3,4-a][2,7]naphthyridines from -hydrazino-7-isopropyl-3-chloro-5,6,7,8-tetrahydro[2,7]naphthyridine-4-carbonitrile were developed. It was shown that heating triazolo[3,4-a][2,7]-naphthyridines in an excess of amines produced isomeric triazolo[5,1-a][2,7]naphthyridine derivatives. These isomers were interconverted using a Dimroth rearrangement. The neurotropic activity of the synthesized compounds was studied.

Expeditious Sonochemical Synthesis of New 1,8-Naphthyridine Derivatives and their Inhibitory Activity on HepG2 Cell Line

A new series of 2-phenyl-1,8-naphthyridine derivatives were synthesized via traditional heating and under ultrasonic irradiation to run out comparative study and confirm the utility of the green chemistry in organic synthesis. An improvement in the rates and yields were observed upon carrying out the reactions under environmentally benign protocol. The newly produced compounds were scanned in vitro for their adverse activity on HepG2 (Human liver) carcinoma cell lines. Results revealed that the tested compounds possess an inhibitory effect on the growth of HepG2 carcinoma cells. The naphthyridinyl pyridine derivatives 4c and 5c showed significant cytotoxic activity. The oxo-pyridine derivative 4c was more potent than the reference drug doxorubicin (DOX), while the imino-pyridine derivative 5c showed slight reduction in the potency. On the other hand, Mannich bases (2a,c,d,e) showed good activity and the styryl derivatives (6b-d) showed moderate activity when compared to (DOX).

Synthesis, crystal structures and photophysical properties of novel copper(I) complexes with 4-diphenylphosphino-1,5-naphthyridine ligands

Two new copper(I) complexes [Cu(L-1)(2))PF6 (L-1 = 4-diphenylphosphino-1,5-naphthyridine, 1) and]Cu(L-2)(2)] PF6 (L-2 = 4-diphenylphosphino-8-methyl-1,5-naphthyridine, 2), have been prepared and characterized. In each of them, the coordinate geometry of Cu atom is a distorted square planar configuration with bond distances and angles in the normal range. Moreover, compound 2 features one-dimensional zigzag chains which are cross-linked by the metal complex cations and PF6- anions through hydrogen bonding interactions. The HOMO-LUMO energy gaps of 1-2 estimated by the cyclic voltammetry (CV) show values in the order of 1 > 2. Both 1 and 2 show low-energy bands ranging from 360 to 430 nm and available florescence in the solid state at room temperature with lambda(max) = 532-541 nm. The UV-vis absorption spectra of 1-2 show obvious red-shifts compared with those of the corresponding quinoline containing Cu(I) complexes [Cu(QN)(2)]PF6 (QN = 8-diphenylphosphino quinoline), exhibiting the HOMO-LUMO energy gaps of 1-2 should be narrower than that of [Cu(QN)(2)]PF6.

Bispyranopyrazoles as Green Corrosion Inhibitors for Mild Steel in Hydrochloric Acid: Experimental and Theoretical Approach

In the present study, we have synthesized two novel corrosion inhibitors BP-1 and BP-2 and evaluated their corrosion inhibition property on mild steel (MS) in acid solution through weight loss and electrochemical corrosion techniques. The corrosion test results reveal that both compounds inhibit corrosion by an adsorption mechanism and display inhibition efficiency more than 95% at a low concentration of 1.72 x 10(-4) M. From the surface analysis of the protective film on MS, it was corroborated that adsorption of inhibitor molecules occurred on the MS surface through chemisorption, which further suppresses the corrosion rate. Density functional theory simulated data helps correlate the experimental trend with the theoretical study.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.

Chemistry of Substituted Thiazinanes and Their Derivatives

Thiazinanes and its isomeric forms represent one of the most important heterocyclic compounds, and their derivatives represented a highly potent drug in disease treatment such as, 1,1-dioxido-1,2-thiazinan-1,6-naphthyridine, which has been shown to have anti-HIV activity by a mechanism that should work as anti-AIDS treatment, while (Z)-methyl 3-(naphthalen-1-ylimino)- 2-thia-4-azaspiro[5 5]undecane-4-carbodithioate showed analgesic activity, cephradine was used as antibiotic and chlormezanone was utilized as anticoagulants. All publications were interested in the chemistry of thiazine (partially or fully unsaturated heterocyclic six-membered ring containing nitrogen and sulfur), but no one was dealing with thiazinane itself which encouraged us to shed new light on these interesting heterocycles. This review was focused on the synthetic approaches of thiazinane derivatives and their chemical reactivity.

Axial interaction of the [Ru-2(CO)(4)](2+) core with the aryl C-H bond: Route to cyclometalated compounds involving a metal-metal-bonded diruthenium unit

Room-temperature activation of the aromatic C-H bond by the [Ru-2(CO)(4)](2+) core has been achieved. The reactions of 2-phenyl-1,8-naphthyridine (phNP) and 2-(2,5-dimethyl-3-furyl)-1,8-naphthyridine (Me-2-fuNP) with [Ru-2(CO)(4)(MeCN)(6)][BF4](2) in dichloromethane provide the agostic-cyclometalated compounds [Ru-2(phNP)(C6H4-NP)(CO)(4)][BF4] (1) and [Ru-2(Me(2)fuNP)(C4OMe2-NP)(CO)(4)][BF4] (2), respectively. In both compounds, one of the ligands is ortho-metalated, while the second ligand is engaged in an agostic interaction. The ortho metalation is preferred over the potential S coordination for 2-(2-thienyl)1,8-naphthyridine (thNP), yielding [Ru-2(thNP)(C4H2S-NP)(CO)(4)][BF4] ( 3). In acetonitrile, the compound [Ru-2(thNP)(2)(CO)(4)][BF4](2) (4) is obtained exclusively. The donation of a C-H bonding electron pair to the Ru-Ru sigma* LUMO and back-donation from the filled Ru-Ru pi* orbital to the C-H sigma* orbital cause facile C-H bond cleavage. In contrast, the isoelectronic [Rh-2](4+) provides the agostic compounds [Rh-2(OAc)(3)(phNP)Cl] (5) and [Rh-2(L)(eta(1)-L)(OAc)(2)(CH3CN)(2)][BF4](2) (L = phNP, np1NP (2-(2- naphthyl)-1,8-naphthyridine) for compounds 6 and 7, respectively). The molecular structures of compounds 1-3, 5, and 7 have been established by X-ray crystallography.
