Ring-Closing Olefin Metathesis Catalyzed by Well-Defined Vanadium Alkylidene Complexes

Vanadium-based catalysts have shown activity and selectivity in ring-opening metathesis polymerization of strained cyclic olefins comparable to those of Ru, Mo, and W catalysts. However, the application of V alkylidenes in routine organic synthesis is limited. Here, we present the first example of ring-closing olefin metathesis catalyzed by well-defined V chloride alkylidene phosphine complexes. The developed catalysts exhibit tolerance to various functional groups, such as an ether, an ester, a tertiary amide, a tertiary amine, and a sulfonamide. The size and electron-donating properties of the imido group and the phosphine play a crucial role in the stability of active intermediates. Reactions with ethylene and olefins suggest that both beta-hydride elimination of the metallacyclobutene and bimolecular decomposition are responsible for catalyst degradation.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 2812-46-6, in my other articles.

HIGHLY SENSITIVE CHEMOSENSOR FOR Cu2+ AND Hg2+ BASED ON ANTHRACENE ANCHORED CALIX[4]ARENE PYRIDINE AMIDE RECEPTOR

In this study, anthracene anchored calix[4]arene pyridine amide (ant-CLX4) receptor was synthesized for the detection of Hg2+ and Cu2+ metal ions and fully characterized by spectroscopic methods. The ion binding properties of ant-CLX4 towards some selected metal ions such as Cu2+, Hg2+, Cr3+, CO2+, Ag+, Tb3+, Zn2+, Cd2+, Ni2+, Ga3+, Mn2+, Yb3+ and Gd3+ were studied by absorption and emission spectra. The ant-CLX4 demonstrated excellent fluorescence response with quenching mechanism (turn-off) in the presence of trace amount of Hg2+ and Cu2+ ions. This quenching response of ant-CLX4 receptor showing the possible binding interaction between ant-CLX4 receptor and metal ions was also observed by a fluorescence color change from bright blue to colorless in presence of metal ions as Hg2+ and Cu2+. Furthermore, the binding stoichiometry of ant-CLX4 with metal ions was confirmed a 1:1 (ant-CLX4-Hg2+ and ant-CLX4-Cu2+) binding model by Job’s Plot method. The detection limits of copper and mercury ions were calculated to be 3.8 x10(-7) M and 3.3 x10(-7) M with a satisfying level for the detection of such ions in the micromolar scale, respectively. This work showed that anthracene anchored calix[4]arene pyridine amide (ant-CLX4) receptor could be used as a member of family of highly sensitive synthetic chemosensor towards toxic ions as Hg2+ and Cu2+.

Structure-Activity Relationships of New Natural Product-Based Diaryloxazoles with Selective Activity against Androgen Receptor-Positive Breast Cancer Cells

Targeted therapies for ER+/PR+ and HER2-amplified breast cancers have improved patient survival, but there are no therapies for triple negative breast cancers (TNBC) that lack expression of estrogen and progesterone receptors (ER/PR), or amplification or overexpression of HER2. Gene expression profiling of TNBC has identified molecular subtypes and representative cell lines. An extract of the Texas native plant Amyris texana was found to have selective activity against MDA-MB-453 cells, a model of the luminal androgen receptor (LAR) subtype of TNBC. Bioassay-guided fractionation identified two oxazole natural products with selective activity against this cell line. Conducted analog synthesis and structure activity relationship studies provided analogs with more potent and selective activity against two LAR. subtype cell line models, culminating in the discovery of compound 30 (CIDD-0067106). Lead compounds discovered have potent and selective antiproliferative activities, and mechanisms of action studies show they inhibit the activity of the mTORC1 pathway.

The Impact of Immunoglobulin G1 Fc Sialylation on Backbone Amide H/D Exchange

The usefulness of higher-order structural information provided by hydrogen/deuterium exchange-mass spectrometry (H/DX-MS) for the structural impact analyses of chemical and post-translational antibody modifications has been demonstrated in various studies. However, the structure-function assessment for protein drugs in biopharmaceutical research and development is often impeded by the relatively low-abundance (below 5%) of critical quality attributes or by overlapping effects of modifications, such as glycosylation, with chemical amino acid modifications; e.g., oxidation or deamidation. We present results demonstrating the applicability of the H/DX-MS technique to monitor conformational changes of specific Fc glycosylation variants produced by in vitro glyco-engineering technology. A trend towards less H/DX in Fc C gamma 2 domain segments correlating with larger glycan structures could be confirmed. Furthermore, significant deuterium uptake differences and corresponding binding properties to Fc receptors (as monitored by SPR) between alpha-2,3- and alpha-2,6-sialylated Fc glycosylation variants were verified at sensitive levels.

Ag1Pd1 Nanoparticles-Reduced Graphene Oxide as a Highly Efficient and Recyclable Catalyst for Direct Aryl C-H Olefination

The efficient and selective palladium-catalyzed activation of C-H bonds is of great importance for the construction of diverse bioactive molecules. Despite significant progress, the inability to recycle palladium catalysts and the need for additives impedes the practical applications of these reactions. Ag1Pd1 nanoparticles-reduced graphene oxide (Ag1Pd1-rGO) was used as highly efficient and recyclable catalyst for the chelation-assisted ortho C-H bond olefination of amides with acrylates in good yields with a broad substrate scope. The catalyst can be recovered and reused at least 5 times without losing activity. A synergistic effect between the Ag and Pd atoms on the catalytic activity was found, and a plausible mechanism for the AgPd-rGO catalyzed C-H olefination is proposed. These findings suggest that the search for such Pd-based bimetallic alloy nanoparticles is a new method towards the development of superior recyclable catalysts for direct aryl C-H functionalization under mild conditions.

The synthetic versatility of the Tiffeneau-Demjanov chemistry in homologation tactics

The Tiffeneau-Demjanov rearrangement can be regarded as an interesting alternative to the more common semi-pinacol transposition. It is usually employed for ring extension but, under specific conditions, it can also be used for ring contraction. Compared to other techniques, such as the Demjanov rearrangement or homologations with diazo compounds, the Tiffeneau-Demjanov pathway presents attractive features including high yielding and selective processes. Ring enlargements follow very strict and simple rules, such as the movement of the less substituted carbon and retention of the configuration. The rearrangement process is mainly affected by steric factors, due to presence of neighbouring groups, rather than electronic ones. The ring contraction may be achieved positioning the amine within the ring, thus achieving a high level of control. Unfortunately, applications of the reaction in modern homologation chemistry are rare; therefore, the aim of the review is re-proposing to the synthetic community the versatility of this venerable reaction and thus, spurring its employment for tackling challenging homologations processes.

Significance of N-moieties in regulating the electrochemical properties of nano-porous graphene: Toward highly capacitive energy storage devices

The effects of N doping concentration and dopant moieties on the electrochemical properties of nanoporous graphene and their dependence on annealing temperature are investigated. Four types of N moieties – amide, amine, graphitic-N, and oxidized-N – are obtained, which transformed into pyridinic-N and pyrrolic-N upon annealing. The diffusion coefficient (0′) of the ions in the electrode is the maximum at 400 degrees C because of a high level of N doping, whereas the second highest D’ value is obtained at 700 degrees C owing to a high level of reduction and N doping. The highest specific capacitance is obtained for the sample annealed at 400 degrees C. (C) 2018 The Korean Society of Industrial and Engineering Chemistry. Published by Elsevier B.V.

Synthesis of Fluorescent Diphenylanthracene-Based Calix[4]arene Derivatives and their Complexation with Alkali Metal Cations

Two novel fluorescent calix[4]arenes comprising diphenylanthracene moiety at the lower rim were synthetizedand their complexation with alkali metal cations in acetonitrile/dichloromethane and methanol/dichloromethane mixtures (phi = 0.5) was studied experimentally and by classical molecular dynamics and quantum chemical calculations. The monosubstituted calixarene derivative (L1) proved to be a poor cation receptor, whereas the ester-based macrocycle (L2) exhibited rather high affinity towards lithium, sodium and potassium cations, particularly in MeCN/CH2Cl2. All complexation reactions were enthalpically controlled, whereby the overall stability was the largest in the case of sodium complex. The computational investigations provided an additional insight into the complexation properties and structures of complex species. The molecular dynamics simulations indicated the occurrence of inclusion of solvent molecules in the calixarene hydrophobic cavity of the free and complexed ligand, which was found to significantly affect the complexation equilibria.
