An process for epoxidizing diversely functionalized olefins by oxorhenium catalysis employs conditions which control water concentration. By controlling water concentration, one can maximize monoperoxo complex formation and increase turnover which subsequently reduces diol side products obtained from epoxide ring opening and increases the yield of the desired epoxide product. The optimal range of water concentrations is 0.50-80.0 mol %. Using less than 0.5 mol % water does not result in practical turnovers and 1.0 equivalent of water (or more) is detrimental to the lifetime of the active catalytic species formed. More particularly, there are four aspects to controlling water concentration: 1) anhydrous oxidants using trialkylsilyl peroxides and an in situ source of BTSP eliminating the need for its isolation; 2) water removal agents including molecular sieves (Aldrich, 3 A, 4 A) and common inorganic dehydrating agents; 3) rhenium catalysts; and 4) a boiling reactor process in the context of oxorhenium catalyzed epoxidation.

The palladium-catalysed direct heteroarylation of the pyridyl-containing substrates, 2-(5-bromothiophen-2-yl)pyridine and 8-bromoquinoline, proceeds in moderate to high yields with a variety of heteroarenes in the presence of 1-2 mol% of a palladium catalyst. This approach allows the access to polyheteroaromatics which are interesting building blocks as (NC)-chelate ligands. The reaction proceeds regioselectively at the C5 position of thiophenes, thiazoles, furans or pyrroles and tolerates various substituents such as formyl, acetyl, ester, nitrile or chloro on the heteroarene. Therefore, this method allows a straightforward modulation of the electron density distribution on such derivatives.

Broadband irradiation of 3,5-diphenylisoxazole 1 in an argon matrix results in formation of azirine 3. Further irradiation of the matrix reduces the amount of azirine 3 with concurrent formation of ylide 4. Thus, it is theorized that the conversion of isoxazole 1 to azirine 3 goes through a triplet vinylnitrene 2 that does not intersystem cross to ketenimine 6. Hence, the reactivity of triplet vinylnitrene 2 is different from similar vinylnitrene intermediates with alpha-methyl substituents that intersystem cross to form corresponding ketenimines. Density functional theory calculations support the notion that the conjugation of the alpha-phenyl group to the vinylnitrene moiety in vinylnitrene 2 renders it more flexible than vinylnitrenes with alpha-methyl substituents, and therefore, vinylnitrene 2 intersystem crosses to azirine 3, rather than ketenimine 6.

One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, Product Details of 300-87-8, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 300-87-8, Name is 3,5-Dimethylisoxazole, molecular formula is C5H7NO

The mechanism and chemoselectivity in the cycloaddition of ynamides and isoxazoles have been explored by the density functional theory (DFT) in model systems composed of a Br°nsted acid (HNTf2), gold(i) [IPrAuNTf2] or platinum(ii) (PtCl2/CO) catalyst, either with or without the presence of H2O. The DFT calculations reveal that all these catalysts entail similar nucleophilic attack of isoxazole on the catalyst-ligated ynamide forming a vinyl intermediate, which can isomerize to an alpha-imino intermediate upon cleavage of the isoxazole N-O bond. The completely distinct reaction pathways are observed after the formation of the alpha-imino intermediate. For the Br°nsted acid catalyst, [5 + 2 + 1] cycloaddition with H2O is the favorable way to generate O-bridged tetrahydro-1,4-oxazepines. If the Br°nsted acid is replaced by a gold(i) catalyst, a [3 + 2] cycloaddition product is produced, either in the absence or in the presence of H2O. Regarding the Pt(ii) catalyst, 1,3-oxazepines are formed through [5 + 2] annulation. Furthermore, the [5 + 2] annulation product in this Pt(ii)-catalyzed system can also be predicted upon addition of H2O. The unique properties of the three selected catalysts were explored in detail through distortion/interaction analysis. The obtained theoretical data account for an observed disparate product formation when using three catalytic systems and provide a theoretical foundation to choose the optimal catalyst for the title reaction. These results can be of particular significance for synthetic chemists toward the design of catalytic systems and cycloaddition transformations involving ynamides, isoxazoles and related derivatives.

Introduction: Pocket-based drug design has contributed to major scientific breakthroughs in pharmaceutical research and development (R&D). The integrated use of experimental and computational methods, primarily during the early phases of drug discovery, has enabled the development of highly potent and selective small-molecule ligands. In this scenario, the targeting of protein-protein interactions (PPIs) has emerged as an attractive strategy for designing innovative drugs for highly complex diseases, such as cancer. Areas covered: This article focuses on the use of experimental and computational approaches with a diversity of PPI classes and discusses the relevant advances in the field, primarily for oncological applications. Analyses of the target binding pockets and medicinal chemistry approaches used to develop promising PPI inhibitors are provided, with an emphasis on data reported over the past 2 years. Expert opinion: PPI drug discovery is a challenging field that depends completely on accurate structural data. The integration of molecular docking, nuclear magnetic resonance and X-ray crystallography is a cornerstone for the current development of effective PPI inhibitors. Although this field has not reached its peak, several compounds have entered clinical trials over the past few years, providing promising perspectives for novel therapies for highly prevalent and life-threatening conditions.
