Author is Wang, Ze-Shu; Chen, Yang-Bo; Zhang, Hao-Wen; Sun, Zhou; Zhu, Chunyin; Ye, Long-Wu.

Here, a novel and practical radical SMILESs rearrangement triggered by photoredox-catalyzed regioselective ketyl-ynamide coupling is reported, which represents the first radical SMILESs rearrangement of ynamides. This method enables facile access to a variety of valuable 2-benzhydrylindoles with broad substrate scope in generally good yields under mild reaction conditions. In addition, this chem. can also be extended to the divergent synthesis of versatile 3-benzhydrylisoquinolines through a similar ketyl-ynamide coupling and radical SMILESs rearrangement, followed by dehydrogenative oxidation Moreover, such an ynamide SMILESs rearrangement initiated by intermol. photoredox catalysis via addition of external radical sources is also achieved. By control experiments, the reaction was shown to proceed via key ketyl radical and α-imino carbon radical intermediates.

A Journal, Journal of Surface Investigation: X-Ray, Synchrotron and Neutron Techniques called Study of Supported Metal Catalysts by the Methods of the Small-Angle Scattering of Neutrons and X-rays, Author is Larichev, Yu. V.; Ivankov, O. I., which mentions a compound: 14898-67-0, SMILESS is Cl[Ru](Cl)Cl.[H]O[H], Molecular Cl3H2ORu, HPLC of Formula: 14898-67-0.

The possibility of analyzing deposited metal catalysts by small-angle neutron scattering through contrast variation based on the use of H2O/D2O mixtures is shown. The use of the contrasting technique makes it possible to selectively obtain the size distribution of metal particles in a wide range of sizes. The reliability of the obtained size distributions of metal particles is confirmed by the addnl. data of transmission electron microscopy and X-ray diffractometry. Variation in the contrast in small-angle neutron scattering with the use of deuterated liquids is shown to have greater possibilities with respect to the structural anal. of deposited catalysts in comparison with small-angle X-ray scattering.

The chemical properties of alicyclic heterocycles are similar to those of the corresponding chain compounds. Compound: [Ir(dtbbpy)(ppy)2]PF6, is researched, Molecular C40H40F6IrN4P, CAS is 676525-77-2, about The Tandem Photoredox Catalysis Mechanism of [Ir(ppy)2(dtb-bpy)]+ Enabling Access to Energy Demanding Organic Substrates, the main research direction is photoredox catalyst photoinduced electron transfer dehalogenation.Application of 676525-77-2.

We report the discovery of a tandem catalytic process to reduce energy demanding substrates, using the [Ir(ppy)2(dtb-bpy)]+ (1+) photocatalyst. The immediate products of photoinitiated electron transfer (PET) between 1+ and triethylamine (TEA) undergo subsequent reactions to generate a previously unknown, highly reducing species (2). Formation of 2 occurs via reduction and semisatn. of the ancillary dtb-bpy ligand, where the TEA radical cation serves as an effective hydrogen atom donor, confirmed by NMR, mass spectrometry, and deuterium labeling experiments Steady-state and time-resolved luminescence and absorption studies reveal that upon irradiation, 2 undergoes electron transfer or proton-coupled electron transfer (PCET) with a representative acceptor (N-(diphenylmethylene)-1-phenylmethanamine; S). Turnover of this new photocatalytic cycle occurs along with the reformation of 1+. We rationalize our observations by proposing the first example of a mechanistic pathway where two distinct yet interconnected photoredox cycles provide access to an extended reduction potential window capable of engaging a wide range of energy demanding and synthetically relevant organic substrates including aryl halides.

Aromatic heterocyclic compounds can be classified according to the number of heteroatoms or the size of the ring. The authors also want to convey more information about this compound (cas:89396-94-1) through the article.

Background: The benefits of percutaneous coronary intervention (PCI) in acute myocardial infarction (AMI) are limited by reperfusion injury. In animal models, nicorandil, a hybrid of an ATP-sensitive K+ (KATP) channel opener and nitrates, reduces infarct size, so the Japan-Working groups of acute myocardial Infarction for the reduction of Necrotic Damage by a K-ATP channel opener (J-WIND-KATP) designed a prospective, randomized, multicenter study to evaluate whether nicorandil reduces myocardial infarct size and improves regional wall motion when used as an adjunctive therapy for AMI. Methods and Results: Twenty-six hospitals in Japan are participating in the J-WIND-KATP study. Patients with AMI who are candidates for PCI are randomly allocated to receive either i.v. nicorandil or placebo. The primary end-points are (1) estimated infarct size and (2) left ventricular function. Single nucleotide polymorphisms (SNPs) that may be associated with the function of KATP-channel and the susceptibility of AMI to the drug will be examined Furthermore, a data mining method will be used to design the optimal combined therapy for post-myocardial infarction (MI) patients. Conclusions: It is intended that J-WIND-KATP will provide important data on the effects of nicorandil as an adjunct to PCI for AMI and that the SNPs information that will open the field of tailor-made therapy. The optimal therapeutic drug combination will also be determined for post-MI patients.

Application of 14898-67-0. Aromatic compounds can be divided into two categories: single heterocycles and fused heterocycles. Compound: Ruthenium(III) chloride xhydrate, is researched, Molecular Cl3H2ORu, CAS is 14898-67-0, about Photo-degradation of salicylic acid over ruthenium oxide incorporated titania bifunctional photo-catalyst: An approach for direct cleavage of Caro-O bond via hydro-deoxygenation. Author is Wu, Wen-Chia; Yang, Chung-Sung; Chang, Chi-Chia.

Ruthenium oxide incorporated titania (RIT) photocatalyst, with verified ruthenium oxide ratio, have been prepared for photo-degradation In monitoring the photo-catalytic reaction of salicylic acid over RIT, two degradation steps are observed The first one is the de-carboxylation. The other step is the hydro-deoxygenation. The final product collected from the degradation is benzene. On the basis of exptl. results, the photo-induced e-h pair from the crystalline domain of titania in RIT plays the key role in inducing the de-carboxylation degradation As for the hydro-deoxygenation reaction, the Ru0/ Ru4+ ratio of incorporated ruthenium oxide in RIT is the pivitol factor in the direct cleavage of Caro–O bond of phenol. The best selectivity for Caro–O bond cleavage (71.9%) is shown in the RIT-1, Ru/Ti = 3.53%, route. If the ratio of Ru/Ti reaches to 10.81% (RIT-3), the selectivity decreases to 4.8%.

Computed Properties of C10H7NO3. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: 4-Hydroxyquinoline-2-carboxylic Acid, is researched, Molecular C10H7NO3, CAS is 492-27-3, about Kynurenic acid in neurodegenerative disorders-unique neuroprotection or double-edged sword?. Author is Ostapiuk, Aleksandra; Urbanska, Ewa M..

A review. The family of kynurenine pathway (KP) metabolites includes compounds produced along two arms of the path and acting in clearly opposite ways. The equilibrium between neurotoxic kynurenines, such as 3-hydroxykynurenine (3-HK) or quinolinic acid (QUIN), and neuroprotective kynurenic acid (KYNA) profoundly impacts the function and survival of neurons. This comprehensive review summarizes accumulated evidence on the role of KYNA in Alzheimer′s, Parkinson′s and Huntington′s diseases, and discusses future directions of potential pharmacol. manipulations aimed to modulate brain KYNA. The synthesis of specific KP metabolites is tightly regulated and may considerably vary under physiol. and pathol. conditions. Exptl. data consistently imply that shift of the KP to neurotoxic branch producing 3-HK and QUIN formation, with a relative or absolute deficiency of KYNA, is an important factor contributing to neurodegeneration. Targeting specific brain regions to maintain adequate KYNA levels seems vital; however, it requires the development of precise pharmacol. tools, allowing to avoid the potential cognitive adverse effects. Boosting KYNA levels, through interference with the KP enzymes or through application of prodrugs/analogs with high bioavailability and potency, is a promising clin. approach. The use of KYNA, alone or in combination with other compounds precisely influencing specific populations of neurons, is awaiting to become a significant therapy for neurodegenerative disorders.
