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.

Catalytic asymmetric synthesis of 1,1-disubstituted tetrahydro-beta- carbolines by phase-transfer catalyzed alkylations

Efficient catalytic asymmetric synthesis of 1,1-disubstituted tetrahydro-beta-carbolines has been achieved via asymmetric alkylation of 1-cyanotetrahydro-beta-carbolines using a binaphthyl-modified N-spiro-type chiral phase-transfer catalyst. This is a valuable example of hitherto difficult highly enantioselective alkylations at alpha-carbon of the cyano group under phase-transfer conditions.

Synthesis of a novel family of photochromic amorphous molecular materials based on dithienylethene, their photochromic properties and application for dual image formation

A novel family of photochromic amorphous molecular materials containing a dithienylethene moiety, 1-{5-[4-(di-p-tolylamino)phenyl]-2-methylthiophen-3-yl}-2- (2,5-dimethylthiophen-3-yl)-3,3,4,4,5,5-hexafluorocyclopentene, 1-{5-[4-(di-p-tolylamino)phenyl]-2-methylthiophen-3-yl}-2- (2-methylbenzo[b]thiophen-3-yl)-3, 3,4,4,5,5-hexafluorocyclopentene and 1,2-bis{5-[4-(di-p-tolylamino)phenyl]-2-methylthiophen-3-yl}-3, 3,4,4,5,5-hexafluorocyclopentene, have been designed and synthesised. These compounds, together with their photocyclised products, were found to readily form amorphous glasses with well-defined glass transition temperatures and to undergo photochromism as amorphous films as well as in solution. These compounds are characterised by high quantum yields for the photocyclisation reactions, very low quantum yields for the reverse ring-opening reactions and, hence, almost 100% fractions of the photocyclised form at the photostationary state in solution. These results suggest that the anti-parallel conformer is more populated than the parallel conformer. Optical dichroism was induced by irradiation of coloured films of the photocyclised compounds with linearly polarised red light, and dual image formation at the same location was realised by utilising this phenomenon.

Discovery of the alpha7 nicotinic acetylcholine receptor agonists. (R)-3?-(5-chlorothiophen-2-yl)spiro-1-azabicyclo[2.2.2]octane-3, 5?-[1?,3?]-oxazolidin-2?-one as a novel, potent, selective, and orally bioavailable ligand

Recent advances in molecular biology suggest that neuronal nicotinic acetylcholine receptors play important roles in the central nervous system (CNS). Of these receptors, the alpha7 group has recently attracted interest for its CNS-related actions and is looked to as a potential new class of pharmacological targets for cognition, schizophrenia, sensory gating, and anxiety. In the course of a research program aimed at the discovery of alpha7 receptor agonists with high affinity, subtype selectivity, and good pharmacokinetic profile, we discovered (R)-3?-(5-chlorothiophen-2-yl) spiro-1-azabicyclo[2.2.2]octane-3,5?-[1?,3?] oxazolidin-2?-one (25). Compound 25 has potent binding affinity (K i = 9 nmol/L) and good selectivity toward the other nicotinic subtypes (alpha4beta2 and alpha1beta2gammadelta) and has been found in pharmacokinetic evaluation to have good oral bioavailability and brain permeability.

Rational design of a visible-light photochromic diarylethene: a simple strategy by extending conjugation with electron donating groups

Photochromic diarylethenes have been widely used in many fields. However, their cyclization process must be induced by UV light. In this article, a simple strategy is developed by extending pi-conjugation with electron donating groups. The modified dirylethene derivative can photocyclolize under 405-nm light with a good photochromic efficiency. Meanwhile, its absorption and moderate fluorescence can be switched effectively in both directions by visible lights (405 and 520 nm, respectively) in different solutions and in living cells. We believe that this simple method will become a versatile strategy for developing various dirylethylenes with visible-light photochromism.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Recommanded Product: 3-Bromo-2-methylbenzo[b]thiophene, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 10243-15-9, in my other articles.

Benzothiophene or benzofuran bridges in diaryl ethenes: Two-step access by Pd-catalyzed C-H activation and theoretical/experimental studies on their photoreactivity

A series of terarylenes incorporating benzothiophene (BT)/benzofuran (BF) as the central ethene unit was synthesised by using sequential Pd-catalysed C – H activation reactions. This new methodology allows the easy modification of the nature of the pendant heteroarene groups. Diaryl ethene (DAE) derivatives with thiophene, thiazole, pyrrole, isoxazole and pyrazole rings were prepared. A large number of asymmetrical DAEs are easily accessible by this new method in both the BT and BF series. The study of their photochromic properties in solution revealed that the nature of the heteroarene and of the central unit drastically modify their photochromic behaviour. TD-DFT calculations were performed to assess the nature of the relevant excited states.

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 6287-82-7, help many people in the next few years.Recommanded Product: 2,3-Dibromobenzo[b]thiophene
