Benzo[b]thiophenium S,C-Ylides: Preparation, structure and comparison with thiophenium analogues

A series of new S,C-ylides derived from benzo[b]thiophene and beta-dicarbonyldiazocompounds were prepared and characterised. NMR (1H,13C) studies revealed that ylides substituted additionally at position 2 of the thiophene ring can exist as pairs of diastereoisomers, not interchangeable at room temperature. The slow exchange between two sites was attributed to the restricted rotation about the ylidic S-C bond. The crystal structure determined for one ylide demonstrated different molecular environment for two parts of the beta-dicarbonyl ylidic substituent with respect to the benzothiophene ring. The prepared ylides were found to be much less reactive than the previously studied thiophenium S,C-ylides.

Carbonyl-containing bisphosphonate esters as novel antiinflammatory and antiarthritic agents

A study of the decomposition of the pyrazoline bisphosphonate ester 2 identified 3 as the sole bisphosphonate component. Evaluation in a delayed- type hypersensitivity granuloma model of chronic inflammation in mice (DTH- GRA) showed 3 to be a potent inhibitor of granuloma formation (sc, 10 mg/kg, 45%), but in a murine model of antigen-induced arthritis (AIA), no significant inhibition was observed. As a result, new ketonic bisphosphonate tetraethyl esters were synthesized from vinylidenebisphosphonic acid tetraethyl ester 4 and activated carbonyl compounds in 13-84% yield. 6 significantly inhibited the pathology of both the DTH-GRA (sc, 25 mg/kg, 45%) and AIA models (sc, 25 mg/kg, 55%). Other compounds in the series were not as potent. Our results show that bisphosphonate ester 6 can inhibit the chronic inflammatory response associated with cutaneous granuloma formation and erosive arthritis.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 130-03-0, help many people in the next few years.Quality Control of Benzo[b]thiophen-3(2H)-one

Enantioselective Construction of Tertiary Boronic Esters by Conjunctive Cross-Coupling

Catalytic enantioselective conjunctive cross-coupling has been developed to construct tertiary alkylboronic esters. These reactions occur with good yield and enantioselectivity for a range of substrates. Mechanistic experiments reveal aspects of the catalytic cycle that allow hindered substrates to react without significant complicating side reactions.

Catalytic Deprotonative alpha-Formylation of Heteroarenes by an Amide Base Generated in Situ from Tetramethylammonium Fluoride and Tris(trimethylsilyl)amine

Heteroarene formylations in DMF solution proceed in the presence of an amide base catalyst generated in situ from tetramethylammonium fluoride (TMAF) and tris(trimethylsilyl)amine (N(TMS)3). The reaction proceeds at room temperature and has an operationally simple procedure. Various heteroarenes, including benzothiophene, thiophene, benzothiazole, oxazole, and indole derivatives, can be formylated with high functional group tolerance.

Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments. category: benzothiophene. Introducing a new discovery about 14315-11-8, Name is 4-Methylbenzo[b]thiophene

A method for measuring 1-octanol-water partition coefficients.

A new direct method to determine the 1-octanol-water partition coefficients (Kow, expressed as log Kow) was tested. A dialysis tubing was used to separate water from the octanol phase containing the analyte (naphthalene, aniline, benzo(b)thiopene, etc.), avoiding the frequently encountered problem of emulsions. Different tubings with molecular weight cutoffs of 2000-12,000 mol wt were equally suitable. The analyte concentrations were determined by LC, allowing compounds to be measured in impure samples. The correlation coefficient was 0.998 for log Kow between experimental and theoretical data. The method quickly determines log Kow without a great hardware expense. A >90% savings in equilibration time can be easily achieved by using ultrasonic agitation. The method is experimentally straightforward.

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.category: benzothiophene, you can also check out more blogs about14315-11-8
