Ruthenium catalysts

A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 15746-57-3, Name is Cis-Dichlorobis(2,2′-bipyridine)ruthenium(II), molecular formula is C20H16Cl2N4Ru. In a Article，once mentioned of 15746-57-3, Formula: C20H16Cl2N4Ru

Synthetic amino acids suitable for the assembly of small, redox-active metallopeptides are described. Nalpha-((1,1-Dimethylethoxy)carbonyl)-N ?-(2-pyridylmethyl)-L-lysine (1), Nalpha-acetyl-S-(2-pyridylmethyl)-L-cysteme (2), and Nalpha-acetyl-S-(2-(2-pyridyl)ethyl)-L-cysteine (3) have been synthesized by alkylation of the Nalpha-protected amino acids. Their [Ru(bipy)2]2+ complexes [(bipy)2Ru(BocLysCH2py)]2+ (4), [(bipy)2Ru(AcCysCH2py)]2+ (5), and [(bipy)2Ru-(AcCys(CH2)2py)]2+ (6) have been prepared by reactions of the ligands with [Ru(bipy)2Cl2]. On the basis of 1H-NMR spectroscopy, 4-6 can be described best as trans-tetrapyridine complexes with the lysine amino N atom and the cysteine S atom occupying one of the apical positions. It was shown by luminescence spectroscopy that 4 can serve as a possible photoredox-active module for the construction of photochemically active peptides. The redox properties of the complexes are described with the aid of the Lever parameters. It was demonstrated that the amino acid ligands in 5 and 6 can be viewed as methionine units. Particularly interesting is the unique redox chemistry of 4. Upon metal oxidation, a two-electron ligand oxidation occurred, followed by fast hydrolytic cleavage of the lysine-methylpyridine N-C bond. The physical and chemical properties of the compounds are discussed in terms of future applications in biomimetic chemistry such as the activation of small molecules.

We performed measurements of magnetic susceptibility, electrical resistivity, and magnetoresistance in magnetic fields of up to 18 T in the magnetic superconductor RuGd1.4Ce0.6Sr2Cu2O10 – delta synthesized in oxygen pressures up to 95 atm. The magnetic-susceptibility data show the occurrence of an antiferromagnetic state below TN? 175 K, followed by the development of a weak ferromagnetic state near TM ? 100 K, and followed further by the onset of superconductivity (SC) at Tc ? 42 K. The electrical resistivity as a function of temperature shows an evolution from nonmetal-to-SC behavior in samples prepared in a flux of O2 to a well defined metal-like behavior in samples prepared under 95 atm pressure of O2. The electron-phonon coupling constant was calculated from transport data to be lambdatr?0.17, a value comparable with other cuprates, indicating weak electron-phonon coupling in these ruthenates. The values of the upper critical field Hc2 for the O2 high-pressure treated samples were obtained from the magnetoresistivity data yielding Hc2ab(0)?39 T, and the out-of-plane superconducting coherence length xic(0) ? (0) ? 28 A . Based on the similarities between these ruthenates and the superconductor YBa2Cu3O7 – delta, we estimated Hc2c(0) ? 8 T and xiab(0) ? 140 A . We used these parameters to discuss the coexistence of long-range magnetic order and superconductivity on a microscopic scale on these materials.

Blockage of more than one oncoprotein or pathway is now a standard approach in modern cancer therapy. Multiple inhibition is typically achieved with two or more drugs. Herein, we describe a pharmacophore merging strategy combining the JAK2/FLT3 inhibitor pacritnib with the pan-HDAC inhibitor, vorinostat, to create bispecific single molecules with both JAK and HDAC targeted inhibition. A preferred ether hydroxamate, 51, inhibits JAK2 and HDAC6 with low nanomolar potency, is <100 nM potent against HDACs 2 and 10, submicromolar potent against HDACs 1, 8, and 11, and >50-fold selective for JAK2 in a panel of 97 kinases. Broad cellular antiproliferative potency is supported by demonstration of JAK-STAT and HDAC pathway blockade in several hematological cell lines, inhibition of colony formation in HEL cells, and analysis of apoptosis. This study provides new tool compounds for further exploration of dual JAK-HDAC pathway inhibiton achieved with a single molecule.

Pinnatoxins belong to an emerging class of potent marine toxins of the cyclic imine group. Detailed studies of their biological effects have been impeded by unavailability of the complex natural product from natural sources. This work describes the development of a robust, scalable synthetic sequence relying on a convergent strategy that delivered a sufficient amount of the toxin for detailed biological studies and its commercialization for use by other research groups and regulatory agencies. A central transformation in the synthesis is the highly diastereoselective Ireland-Claisen rearrangement of a complex alpha,alpha-disubstituted allylic ester based on a unique mode for stereoselective enolization through a chirality match between the substrate and the lithium amide base. With synthetic pinnatoxin A, a detailed study has been performed that provides conclusive evidence for its mode of action as a potent inhibitor of nicotinic acetylcholine receptors selective for the human neuronal alpha7 subtype. The comprehensive electrophysiological, biochemical, and computational studies support the view that the spiroimine subunit of pinnatoxins is critical for blocking nicotinic acetylcholine receptor subtypes, as evidenced by analyzing the effect of a synthetic analogue of pinnatoxin A containing an open form of the imine ring. Our studies have paved the way for the production of certified standards to be used for mass-spectrometric determination of these toxins in marine matrices and for the development of tests to detect these toxins in contaminated shellfish.

Certain dienynes give cyclorearrangement by tandem cyclopropanation/ring-closing alkene metathesis, triggered by either a ruthenium carbene or noncarbene ruthenium(II) precatalyst. The process represents a variation of enyne metathesis where presumed cyclopropyl carbene intermediates undergo a consecutive ring-closing metathesis. A mechanistic proposal is offered, and sequential use of catalysts provided a tandem ring-closing enyne/alkene metathesis product. Copyright

In this study, ruthenium(ii)-catalyzed direct hydrosilylation of internal alkynes with high regio-selectivity and stereo-selectivity is reported. This title transformation led to various vinylsilanes in good to excellent yields. This approach features mild reaction conditions, low catalyst loading, air-stability, and good functional group tolerance. Furthermore, gram-scale preparation and some transformations of vinylsilanes were carried out, which further underscored its synthetic utility and applicability.
