Cascade Trisulfur Radical Anion (S-3(center dot-)) Addition/Electron Detosylation Process for the Synthesis of 1,2,3-Thiadiazoles and Isothiazoles

Trisulfur radical anion (S-3(center dot-)) mediated reactions with in situ formed azoalkenes and alpha,beta-usaturated N-sulfonylimines for the construction of 1,2,3-thiadiazoles and isothiazoles has been developed. S-3(center dot-) is in situ generated from potassium sulfide in DMF. These two approaches provide a new, safe, and simple way to construct 4-subsituted 1,2,3-thiadiazoles, 5-subsituted 1,2,3-thiadiazoles, and isothiazole in good yields. The reactions include the formation of the new C-S and N-S bonds via S-3(center dot-) addition and electron detosylation under mild conditions.

A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 18621-17-5. COA of Formula: C16H17NO.

Transition Metal-Free Synthesis of Substituted Isothiazoles via Three-Component Annulation of Alkynones, Xanthate and NH4I

A protocol was described to access diverse isothiazoles with functionalization potential via transition metal-free three-component annulation of alkynones, potassium ethylxanthate (EtOCS2K) and ammonium iodide (NH4I). A sequential regioselective hydroamination/thiocarbonylation/intramolecular cyclization cascade achieved the efficient formation of consecutive C-N, C-S and N-S bonds in a one-pot process.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 103-60-6, you can contact me at any time and look forward to more communication. SDS of cas: 103-60-6.

Isothiazole ring skeleton was formed by the treatment elf substituted 2-alkylthio-3-acyl-4-quinolinone with O-(mesitylene-sulfonyl)hydroxylamine(MSH). A mixture of alkyl transferred 3-methyl-9-alkyl-4,9-dihydroisothiazolo[5,4-b]quinolin-4-one as a major product and dealkylated 3-methyl-4,9-dihydroisothiazolo[5,4-b]quinolin-4-one as a minor product was obtained from unsubstituted 2-alkylthio-3-acyl-4-quinolinone in the presence of K2CO3. When 2 equivalents of MSH were used in the absence of K2CO3 only dealkylated product was obtained in quantitative yield.

Quantum-Chemical Investigation of Azoles 1. Alternative Electrophilic Substitution Mechanisms in 1,2-and 1,3-Azoles

Quantum-chemical calculations were performed for the molecular structures of 1,2-azoles (pyrazole, isoxazole, isothiazole), 1,3-azoles (imidazole, oxazole, thiazole), and the corresponding intermediates of electrophilic substitution reactions (with protons as the model electrophiles): azolium ions, bipolar ions (ylides/carbenes), cationic sigma-complexes, as well as activation energy values were calculated for the decomposition of ylides. The calculations were performed for gas phase and aqueous solutions according to the B3LYP method in a 6-31G(d) basis set, with corrections for the zero-point vibration energy. The solvation effects were taken into account by using the overlapping spheres model (IEFPCM). The results of the calculations explained some features of electrophilic substitution in azoles according to two alternative mechanisms: the classical addition-elimination with cationic sigma-complex intermediates, and the mechanism of elimination-addition that involves ylides (carbenes) as key intermediates.

New routes to benzothiophenes, isothiazoles and 1,2,3-dithiazoles

4,5-Dichloro-1,2,3-dithiazolium chloride 1 condenses with active methylene compounds, such as malononitrile, barbituric acid and Meldrum’s acid, to give the dithiazol-5-ylidene derivatives, such as 3, 4 and 5, in modest yields. Better yields are obtained from 4-chloro-1,2,3-dithiazole-5-thione 6. Thus the thione 6 condenses with diphenyldiazomethane in a very mild version of the Barton double extrusion synthesis of hindered alkenes; this requires neither heat to extrude nitrogen nor a phosphine to abstract sulfur, to give the alkene 7 (83%) (Scheme 1). This alkene rearranges at room temperature, with loss of hydrogen chloride and sulfur, to give the benzothiophene 13 (89%) in a new thiophene ring-forming reaction (Scheme 2). The thione 6 also condenses with tetracyanoethylene oxide to give a better yield of the dicyanomethylene compound 3 (70%) (Scheme 4). Compound 3, in turn, reacts with morpholine and with chloride ions (Scheme 5) to give 3-morpholino-19 (60%) and 3-chloro- 20 (100%) isothiazole-4,5-dicarbonitrile, in a new isothiazole ring synthesis. Mechanisms are proposed for all of these reactions.

Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law. In my other articles, you can also check out more blogs about 1775-95-7. Formula: C13H10N2O3.

Volatile constituents from in vitro and ex vitro plants of Petiveria alliacea L.

In this work, the volatile compounds extracted by simultaneous distillation and extraction as well as the volatile constituents by solid phase micro-extraction (SPME) from different structures (in vitro and ex vitro roots, leaves, and inflorescence) of Petiveria alliacea were analyzed by GC/FID and GC/MS. Forty-one different compounds were identified. Differences were observed between plant structures and origin (either in or ex vitro). However, sulfur compounds were common to all samples, like bis(phenyl-methyl)-disulfyde, isothiazole (1,2-thiazole), 2-thiopropane, dimethyl sulphyde, ethylene disulfyde, and 2,3-dimethyl-thiirane. In vitro plant roots exhibited higher chemical diversity among the analyzed plant structures. Substances found in all analyzed structures of P. alliacea by SPME were benzaldehyde, calamenene and the hydrocarbons dodecane, tridecane, and tetradecane.

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 103-60-6. Category: isothiazole.
