Alkylation of 1,3-benzothiazin-4-one 2-oxo-, 2-arylimino-, and 2-thioxo derivatives

Sodium salt of 3De -benzo[e][1,3]thiazine-2,4-dione is easily alkylated at position 3. In the case of 2-(arylimino)-2,3-dihydrobenzo[e][1,3]-thiazin-4-ones, the alkylation reaction at this position occurs regioselectively. Alkylation of 2-thioxo-2,3-dihydrobenzo[e][1,3]thiazin-4-one under the same conditions produced regioisomers, but S-alkylation at the exocyclic sulfur atom occurred in the presence of triethylamine. The reaction of 1-(4-oxo-3,4-dihydrobenzo[e][1,3]thiazin-2-ylidene)guanidine with methyl anthranilate led to the formation of tetracyclic quinazolinD3/4[2,1-b]quinazolinedione.

SYNTHESIS AND ANTIMICROBIAL ACTIVITY OF NOVEL OXAZOLIDINONES HAVING BENZO THIAZINE DERIVATIVES

In order to develop relatively small molecules as pharmacologically active molecules, a series of novel oxazolidinones having benzothiazine and their derivatives were synthesized and characterized by IR, H-1 NMR and Mass spectral studies. Various substituted oxazolidinone benzothiazines were prepared by simple refluxing in the presence of acetonitrile. Treatment of these oxazolidinone benzothiazine derivatives with methanesulfonyl chloride gives its sulphonate derivatives which on further treatment with sodium azide and triphenyl phosphine in acetic anhydride gave acetamide derivatives. Further the synthesized compounds were evaluated for antibacterial activity against Bacillus subtilis, Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa and antifungal activity against Candida albicans and Aspergillus niger.

Organic dyes festooned with fluorene and fused thiazine for efficient dye-sensitized solar cells

Five new metal free organic dyes festooned with fluorene and fused thiazine structural units such as FPAA1, FPAA2 and FPTAA1-FPTAA3 have been synthesized by adopting multistep synthetic strategy and investigated nanocrystalline TiO2 based dye-sensitized solar cell performance by utilizing the same as sensitizers. Further, electrochemical, photophysical, and computational studies have been explored. Computational studies have been carried out to determine the electronic distribution within the molecules. Of the devices fabricated, the ones incorporated with cyanoacrylic acid acceptor exhibit greater power conversion efficiencies along with superior electron life time, short-circuit current and open-circuit voltage than the others integrated with (4-oxo-2-thioxothiazolidin-3-yl)acetic acid acceptor. Among them, the dye FPAA1 possessing device exhibited highest PCE of 7.54% besides open circuit voltage (V-OC) of 751 mV, short circuit current density (J(SC)) of 15.65 mA cm(-2), and fill factor (ff) of 0.60.

Breslow Intermediates from a Thiazolin-2-ylidene and Fluorinated Aldehydes: XRD and Solution-Phase NMR Spectroscopic Characterization

The first generation and X-ray diffraction (XRD) analysis of a crystalline Breslow intermediate (BI) derived from a thiazolin-2-ylidene, that is, the aromatic heterocycle present in vitamin B-1, is reported. Key to success was the combined use of pentafluorobenzaldehyde and a thiazolin-2-ylidene carrying an enol-stabilizing dispersion energy donor as N-substituent. A so-called primary intermediate (PI) could be isolated in protonated form (pPI) as well and analyzed by XRD. Furthermore, the first stable BI derived from an aromatic thiazolin-2-ylidene and an aliphatic aldehyde (trifluoroacetaldehyde) was prepared and characterized by NMR spectroscopy in solution. When switching to a saturated thiazolidin-2-ylidene, reaction with pentafluorobenzaldehyde afforded a new BI in solution (NMR spectroscopy). Attempts to crystallize the latter BI resulted in the isolation of a novel thiazolidin-2-ylidene dimer that had undergone rearrangement to a hexahydro[1,4]-thiazino[3,2-b]-1,4-thiazine.

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 5326-23-8. HPLC of Formula: https://www.ambeed.com/products/5326-23-8.html.

The Metabolism of Methylene Blue and Its Derivatives in Japanese Eel (Anguilla Japonica)

Methylene blue (MB) is commonly used in aquaculture as a fungicide and antidotes. This study was designed to explore the pharmacokinetics of MB in Japanese eel (Anguilla Japonica) immersed in 10 mg L-1 and 20 mg L-1 MB for 0.5 h. The concentrations of MB and its derivatives in the blood, liver, kidney, skin and muscle were determined by HPLC after immersion. The results showed that the changes of drug concentrations in Japanese eel were basically the same in different dose groups, showing a general trend of increasing at first and then decreasing, but the peak time was slightly different. The peak concentration of the drug was positively correlated with the dose level. The peak concentrations of MB in MB (20 mg L-1) group, MB, azure A and azure B in the tissues of Japanese eel were significantly higher than those in MB (10 mg L-1) group. Moreover, MB, azure A and azure B remained for a long time and could still be detected at 64 days, and azure C was not detected in tissues.

Widely Electronically Tunable 2,6-Disubstituted Dithieno[1,4]thiazines-Electron-Rich Fluorophores Up to Intense NIR Emission

2,6-Difunctionalized dithieno[1,4]thiazines were efficiently synthesized by (pseudo)five- or (pseudo)three-component one-pot processes based on lithiation-electrophilic trapping sequences. As supported by structure-property relationships, the thiophene anellation mode predominantly controls the photophysical and electrochemical properties and the electronic structures (as obtained by DFT calculations). From molecular geometries and redox potentials to fluorescence quantum yields in solution, the interaction of the dithieno[1,4]thiazine-core with the substituents causes striking differences within the series of regioisomers. Most interestingly, strong acceptors introduced inanti-antidithieno[1,4]thiazines nearly induce a planarization of the ground-state geometry and a highly intense NIR fluorescence (phi(F)=0.52), whereas an equally substitutedsyn-syndithieno[1,4]thiazine exhibits a much stronger folded molecular structure and fluoresces poorly (phi(F)=0.01). In essence, electrochemical and photophysical properties of dithieno[1,4]thiazines can be tuned widely and outscore the compared phenothiazine with cathodically shifted oxidation potentials and redshifted and more intense absorption bands.

Organo-nanocatalysis: An emergent green methodology for construction of bioactive oxazines and thiazines under ultrasonic irradiation

A synergistic catalysts system ZnO NPs and Malic acid was used for the highly efficient and eco-friendly synthesis of oxazines and thiazines derivatives. Aldehyde, urea and alkyne derivatives are used as reactants under ultrasonication, which not only allows clean and rapid alteration but also simplifies experimental setup.
