Two Approaches for the Synthesis of Fused Dihydropyridines via a 1,6-Electrocyclic Reaction: Fluorescent Properties and Prospects for Application

Reactions of penta-2,4-dienethioamides with acetylenedicarboxylic acid, methyl and ethyl esters, and methyl propiolate were systematically studied, and a number of new 2,3-dihydro-5H-thiazolo-[3,2-a]pyridines (DTPs) and 4H,6H-pyrido[2,1-b][1,3]thiazines (PTZs) were prepared. A possible mechanism for a multistep domino transformation is suggested, and the key step is the 1,6-electrocyclic reaction. An additional alternative method for the synthesis of new heterocyclic systems was achieved. Evidence of the electrocyclic mechanism of a key step was collected from the analysis of the spatial structure of the synthesized bicyclic nonaromatic pyridines by X-ray diffraction and quantum chemical calculations, as well as from the thermodynamic quantities. DTPs exhibited yellow fluorescence in solution and yellow to red emissions in the solid state. Biological investigations demonstrated the ability of DTPs to penetrate living and fixed cells and presumably accumulate in lysosomes.

Electrochemical Evaluation and DFT Studies of 2-(4-chlorophenyl)-3-hydroxy-4,6-dioxo-8-phenyl-4,6-dihydropyrimido[2,1-b][1,3]thiazine-7-carbonitrile of Carbon Steel Corrosion in Hydrochloric Acid

In present study corrosion inhibition property of 2-(4-chlorophenyl)-3-hydroxy-4,6-dioxo-8-phenyl-4,6-dihydropyrimido[2,1-b][1,3]thiazine-7-carbonitrile (CHPPC) in 1.0 M HCl was investigated using electrochemical impedance spectroscopy, potentiodynamic polarization and DFT studies. From electrochemical measurements it is observed that inhibition efficiency increases with CHPPC concentration and maximum efficiency (98.9) was obtained at 1.0 mM. The potentiodynamic study reveals that pyrimidothiazine derivative is a mixed type inhibitor with predominant cathodic action. EIS plot indicates that the addition of inhibitor increases the charge-transfer resistance (Rct) and decreases the double-layer capacitance (Cdl) of the corrosion process, these observation reveal that investigated pyrimidothiazine derivative inhibits carbon steel corrosion by adsorption mechanism. Adsorption of pyrimidothiazine derivative on carbon steel surface obeys the Langmuir adsorption isotherm. The effect of temperature on the corrosion rate was investigated and some thermodynamic parameters were also calculated in order to explain the mechanism of adsorption. A theoretical study of the corrosion inhibition efficiency of this pyrimidothiazine derivative, was carried out using density functional theory (DFT) at the B3LYP/6-31G(d) level of theory.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 7143-01-3. COA of Formula: C2H6O5S2.

Decolorization of heterocycle dye Neutral Red by white-rot fungus Perenniporia subacida

A white-rot fungus Perenniporia subacida was developed for decolorizing twelve structurally various dyes from anthraquinone, azo, heterocycle, thiazine, and triphenylmethane groups. Among them, heterocycle dye Neutral Red with preferable decolorization performance was selected for further experiments and this strain could be utilized sequentially for three consecutive cycles with declining decolorization (%). After a 10-day incubation period, higher dye uptake (96.56%) was obtained at constant inoculum and agitation speed with the optimum physicochemical parameters like initial pH at 4.0, temperature at 35 degrees C, initial dye concentration at 100 mg/L, and ionic strength at 0.1 mol/L. Noteworthy induction of various dye decolorizing enzymes viz. lignin peroxidase, laccase, manganese peroxidase, tyrosinase, and nicotinamide-adenine dinucleotide hydrogen-2,6-dichlorophenol indophenol reductase compared to control, point out toward their involvement in overall decolorization and degradation process. Analytical studies like fourier transform infrared spectroscopy and gas chromatography-mass spectroscopy were used to identify the degraded metabolites and scrutinize the degradation process. Phytotoxicity studies indicated that the fungal treatment favors detoxification of dye Neutral Red. It is suggested that P. subacida has great potential for decolorizing heterocycle dyes.

New short and general synthesis of three key Maillard flavour compounds: 2-Acetyl-1-pyrroline, 6-acetyl-1,2,3,4-tetrahydropyridine and 5-acetyl-2,3-dihydro-4H-1,4-thiazine

A new general synthetic route towards three key Maillard flavour compounds, namely 2-acetyl-1-pyrroline, 6-acetyl-1,2,3,4-tetrahydropyridine and 5-acetyl-2,3-dihydro-4H-1,4-thiazine, was developed. The key step in the process is the methylenation reaction of azaheterocyclic carboxylic esters by means of dimethyltitanocene, giving rise to intermediate vinyl ethers which can be considered as excellent and stable precursors for the title compounds, as a simple acidic treatment of these precursors suffices to release the characteristic Maillard flavours.

DECOLORIZATION KINETICS OF ACID AZO DYE AND BASIC THIAZINE DYE IN AQUEOUS SOLUTION BY UV/H2O2 AND UV/FENTON: EFFECTS OF OPERATIONAL PARAMETERS

The photochemical decolorization of two dyes, namely Acid Yellow 54 and Basic Blue 9, was studied using the UV/H2O2 and UV/Fenton processes. The effects of the amount of H2O2 and FeSO4 as well as the initial pH solution on decolorization kinetics of both the dyes were investigated. The pseudo-first order kinetic model was applied to predict the decolorization of the selected dyes at the different operational conditions and results showed that this model fitted very well with the experimental data. The obtained results also showed the efficiency of UV/Fenton process to quickly degrade aqueous effluents polluted by Acid Yellow 54 and Basic Blue 9 compared to the UV/H2O2 process.

2,1-Benzothiazine 2,2-Dioxides. 5. Hydrolysis of Alkyl 1-R-4-Hydroxy-2,2-Dioxo-1H-2 lambda(6),1-Benzo-Thiazine-3-Carboxylates

Hydrolysis of 1-R-4-hydroxy-2,2-dioxo-1De-2 lambda(6),1-benzothiazine-3-carboxylate esters in HCl-AcOH-H2O mixture at 60A degrees D was accompanied by decarboxylation and led to 1-R-4-oxo-3,4-dihydro-1H-2 lambda(6),1-benzo-thiazine-2,2-diones. In the alkaline medium, regardless of the type of the substituent at position 1, analogous structural transformations occurred at first, but the thiazine ring was also destroyed along with the ester fragment when performing the reaction for a longer time.

Ecofriendly pH-Tunable Hydrogels for Removal of Perilous Thiazine Dye

Reactive dyes are extremely toxic and harmful to the environment even present at very low concentration. In this study, sodium alginate based reusable hydrogels was prepared for the removal of methylene blue from waste water. pH-tunable hydrogels was prepared by the introduction of ionic pendant functionalities on sodium alginate (SA) by the utilization of ethylene glycol and acrylic acid through condensation followed by free radical polymerization. The structure, formation and thermal stability of hydrogel was identified by Fourier transform infra red spectroscopy and thermogravimetric analysis respectively. Swelling nature at different pH ranges and the humidity contents of both dried and dye adsorbed hydrogels was investigated. The morphology of the dry and dye adsorbed hydrogel was also studied using scanning electron microscopy. The swelling studies infer that pronounced swelling obtained at higher pH than at lower pH. The surface morphology of plain hydrogel before and after adsorption of methylene blue (MB) was examined by SEA analysis. The adsorption tendency of the SEA hydrogel in MB was steadily investigated at different pH, contact time, concentration dye and adsorbent dosage. All prepared hydrogels were performed well in the removal of MB from waste water up to 80-98%. Recycling of hydrogels has a vital role for waste water treatment and it can be done by desorption studies which shows that 0.1 N HCl revealed higher elution efficiency i.e. 90.00%. Furthermore, adsorption-desorption studies suggested that SA based hydrogels contributes to enhance the removal efficacy, which renders the hydrogels well-designed for the efficient removal of cationic dyes (MB). However, polyol based hydrogels have been chosen for an adsorbent because of low-cost, ecofriendly, biocompatible and efficient biosorbents. [GRAPHICS] .

Crystal structure of meso-3,3 ‘-(1,4-ohenylene)bis(2-phenyl-2,3,5,6-tetrahydro-4H-1,3-thiazm-4-one)

The crystal structure of the title compound – meso-C26H24N2O2S2 with two stereocenters – has half the molecule in the asymmetric unit with the other half generated by a crystallographic center of inversion. The thiazine ring is in a conformation that is between half-chair and envelope [theta = 52.51 (17)degrees]. The phenyl ring on the 2-carbon atom of the thiazine ring is pseudo-axial. The central phenyl ring of the molecule is close to orthogonal to the phenyl rings on either side with an angle of 76.85 (11)degrees between those planes. In the crystal, pairwise, weak C-H center dot center dot center dot O hydrogen bonds between the central phenyl ring and the oxygen atoms of neighboring molecules result in continuous strips propagating along the a-axis direction. Hydrophobic interactions of the C-H center dot center dot center dot pi type are also observed.
