Synthesis of Fused 1,2,4-Dithiazines and 1,2,3,5-Trithiazepines

Reacting (Z)-N-(4-chloro-5H-1,2,3-dithiazol-5-ylidene)-1H-pyrazol-5-amines 5 with Et2NH and then with concd H2SO4 gives 5H-pyrazolo[3,4-e][1,2,4]dithiazine-3-carbonitriles 7 in good yields (74-85%) and 6H-pyrazolo[3,4-f][1,2,3,5]trithiazepine-4-carbonitriles 9 as minor products (0-6%). Furthermore, the 1,3-dimethylpyrazole analogue 5a was transformed into the dithiazine 7a in two discrete steps, allowing the isolation of a disulfide intermediate (Z)-2-[(diethylamino)disulfan-yl]-2-[(1H-pyrazol-5-yl)imino]acetonitrile (8a). The one-pot, two-step reaction also worked with electron-rich hydroxy- and methoxy-substituted anilines. Thermolysis of the pyrazolo[3,4-e][1,2,4]dithiazines 7 gave the ring-contracted 1H-pyrazolo[3,4-d]thiazole-5-carbonitriles 6 (94-100%). With active sulfur, 1,3-dimethyl-5H-pyrazolo[3,4-e][1,2,4]dithiazine-3-carbonitrile (7a) gave 1,3-dimethyl-6H-pyrazolo[3,4-f][1,2,3,5]trithiazepine-4-carbonitrile (9a), but on prolonged reaction times, it gave 5,7-dimethyl-5H-[1,2,3]dithiazolo[4,5-b]pyrazolo[3,4-e][1,4]thiazine (13). Finally, in the absence of acid, heating a solution of (Z)-2-[(diethylamino)disulfanyl]-2-[(1,3-dimethyl-1H-pyrazol-5-yl)imino]acetonitrile (8a) gave 4,6,10,12-tetramethyl-6H-pyrazolo[3,4-f]pyrazolo[3′,4′:4,5]pyrimido[6,1-d][1,2,3,5]trithiazepine-8,12b(10H)-dicarbonitrile (19) (67%).

Electric Literature of 92-30-8, Consequently, the presence of a catalyst will permit a system to reach equilibrium more quickly, but it has no effect on the position of the equilibrium as reflected in the value of its equilibrium constant.I hope my blog about 92-30-8 is helpful to your research.

Synthesis and antioxidant activity of some 1-aryl/aralkyl piperazine derivatives with xanthine moiety at N4

Piperazine nucleus is one of the most important heterocyclic systems exhibiting remarkable pharmacological activities. Thus, in the current study six new aryl/aralkyl substituted piperazine derivatives, containing methylxanthine moiety were synthesized and their structures were confirmed by IR and H-1 NMR analysis. All compounds were in vitro screened for their activity as antioxidants using DPPH (2,2 ‘-Diphenyl-1-picrylhydrazyl), ABTS (2,2 ‘-azinobis-(3-ethylbenzo thiazine-6-sulfonic acid)) and FRAP (ferric reducing/antioxidant power) methods. The antioxidant activity of the studied compounds against lipid peroxidation was also measured. The highest antioxidant activity was demonstrated by compound 3c. It is obvious that the presence of a hydroxyl group in the structure is essential for the antioxidant properties and should be taken into consideration in further design of structures with potential antioxidant properties.

EXPERIMENTAL AND THEORETICAL INVESTIGATION OF OPTICAL SPECTRA OF METHYLENE GREEN IN SOLUTIONS

The hybrid multilevel approach based on molecular dynamics, quantum mechanics, and statistical theory has been applied to profiles of electronic absorption bands of a number of thiazine dyes (phenothiazine, methylene blue, and methylene green), whose photochemical and biological properties depend on the external medium. The effect of single fragments of the methylene green (MG) molecule on its spectral-luminescent properties is studied. The most preferred geometry for the MG molecule is identified, and its relations with the spectral properties and the solvent nature are established. The energies of the electron states are calculated, and their nature is revealed. The electrostatic potential is analyzed, and the places of the most probable interaction of the molecule with the medium are found. Conclusions on the mechanism of forming the MG absorption spectrum are made based on the observations and calculations performed within the framework of the present work. It is established that the formation of the N-H bonds leads to the formation of an inactive lower excited singlet state and delocalization of the electron charge upon excitation. The position of the maximum of the long-wavelength absorption band of the MG correlates with the donor number of solvents in the series acetonitrile < water < ethanol < isopropanol < dimethyl sulfoxide. The position of the MG electron transition in the region of 630 nm is determined by the interaction of nitrogen and sulfur atoms of the central ring rather than by the increased number of substituents in the structure of the molecule.

An Efficient One-Pot Synthesis of Benzo[1,4]Thiazines, Benzo[1,3]Thiazoles and Benzo[1,5] Thiazepines

Background: One-pot reactions have gained considerable and wide range of interests in the field of chemistry due to their simplicity and economy. Comparing to the step-by-step reactions that involve the formation of individual bonds for a given target product, the greatest attribute of one-pot reactions, is the formation of several bonds in one-pot operation without intermediate isolation, reaction condition changing and further reagents adding. Objective: We developed an one-pot, rapid, simple and eco-friendly synthetic strategy for benzothiazines, benzothiazoles and benzothiazpines through the interaction of o-aminothiophenol with ketones, nitriles and chalcones, respectively. Method: A mixture of o-aminothiophenol ketones, nitriles and chalcones was refluxed or stirred at room temperature in glacial acetic acid containing a catalytic amount of concentrated H2SO4 for 3h. Then, the resulting precipitate was collected by filtration, washed with water and crystallized from the appropriate solvent. Results: The interaction of o-aminothiophenol with aromatic and aliphatic ketones containing active alpha-hydrogens afforded the corresponding 2H-benzo[1,4] thiazines and 4H-benzo[1,4] thiazines, respectively. Similarly, the cyclic ketones afforded the corresponding tricyclic compounds. Treatment of o-aminothiophenol with nitriles under the same reaction condition gave benzo[1,3] thiazoles. Further, cyclocondensation with chalcones under the same reaction condition at room temperature yielded the corresponding benzo[1,5] thiazepines. The reaction mechanism was investigated and the structures of all new compounds were elucidated using spectral analysis. Conclusion: An efficient, simple and environmentally friendly synthesis of benzothiazines, benzothiazoles and benzothiazepines in one-pot synthesis has been developed. With this catalytic reaction, a very cheap sulfuric acid was used as a catalyst.

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 2235-54-3 is helpful to your research. Product Details of 2235-54-3.

Synthesis, Anticancer Evaluation, and Molecular Docking Studies of Novel (4-Hydroxy-2-Thioxo-3,4-Dihydro-2H-[1,3]Thiazin-6-Yl)-Chromen-2-Ones via a Multicomponent Approach

A series of coumarin-substituted 1,3-thiazine-2-thione derivatives (4a-m) were synthesized via the multicomponent reaction of 3-chloro-3-(2-oxo-2H-chromen-3-yl)acrylaldehyde (1) carbon disulfide (2), and various primary amines (3), in presence of triethylamine and acetonitrile under stirring with good yields. The structures of all the synthesized compounds were characterized by analytical and spectral studies. Further, the synthesized compounds were screened for their in vitro antiproliferative activities against different cancer cell lines (A549, MDA-MB-231, MCF7, HeLa, and B16F10). Studies on the molecular interactions to recognize the hypothetical binding motif of the title compounds with the target Hsp 100 were carried out employing the Schrodinger software. Compounds 4a, 4c and 4m showed activity against all the five cell lines compared with the reference drug, and 4a exhibited the least IC50 concentration of 7.56 +/- 1.07g/mL against MCF7. This in vitro anticancer result was supported by in silico docking and in silico ADME (absorption, distribution, metabolism, and excretion) studies as well.

Stereoselective Polymer-Supported Synthesis of Morpholine- and Thiomorpholine-3-carboxylic Acid Derivatives

Herein we report the polymer-supported synthesis of 3,4-dihydro-2H-1,4-oxazine-3-carboxylic acid derivatives using immobilized Fmoc-Ser(tBu)-OH and Fmoc-Thr(tBu)-OH as the starting materials. After the solid-phase-synthesis of N-alkyl-N-sulfonyl/acyl intermediates, the target dihydrooxazines were obtained using trifluoroacetic acid-mediated cleavage from the resin. This approach was also studied for the preparation of dihydrothiazines from immobilized Fmoc-Cys(Trt)-OH. Inclusion of triethylsilane in the cleavage cocktail resulted in the stereoselective formation of the corresponding morpholine/thiomorpholine-3-carboxylic acids. Stereochemical studies revealed the specific configuration of the newly formed stereocenter and also the formation of stable N-acylmorpholine rotamers.
