Methylated cyclodextrins: An efficient protective agent in water for zerovalent ruthenium nanoparticles and a supramolecular shuttle in alkene and arene hydrogenation reactions

Zerovalent ruthenium(0) nanoparticles in the size range of 2.5 nm were easily prepared by chemical reduction of ruthenium salt with an excess amount of sodium borohydride and were efficiently stabilized by methylated cyclodextrins. The optimization of the catalytic system has been carried out in terms of stability and catalytic activity, considering the hydrogenation of olefinic compounds under biphasic liquid-liquid conditions. Efficient and controlled chemoselectivities were obtained in the hydrogenation of arene derivatives by the relevant choice of cavity and methylation degree of the cyclodextrins. Finally, the hydrogenation of alpha- and beta-pinenes leads to the major formation of cis-pinanes, interesting synthons for fine chemistry, with high diastereoisomeric excesses.

Poly(alkylidenimine) dendrimers functionalized with the organometallicmoiety [Ru(nu 5-C5H5)(PPh3)2]+ as promising drugs against cisplatin-resistant cancer cells and humanmesenchymal stem cells

Here and for the first time, we show that the organometallic compound [Ru(nu5-C5H5)(PPh3)2Cl] (RuCp) has potential to be used as a metallodrug in anticancer therapy, and further present a new approach for the cellular delivery of the [Ru(nu5-C5H5)(PPh3)2]+ fragment via coordination on the periphery of low-generation poly(alkylidenimine) dendrimers through nitrile terminal groups. Importantly, both the RuCp and the dendrimers functionalized with [Ru(nu5-C5H5)(PPh3)2]+ fragments present remarkable toxicity towards a wide set of cancer cells (Caco-2, MCF-7, CAL-72, and A2780 cells), including cisplatin-resistant human ovarian carcinoma cell lines (A2780cisR cells). Also, RuCp and the prepared metallodendrimers are active against human mesenchymal stem cells (hMSCs), which are often found in the tumor microenvironment where they seem to play a role in tumor progression and drug resistance.

A Convergent Synthetic Strategy towards Oligosaccharides containing 2,3,6-Trideoxypyranoglycosides

A de novo synthetic strategy for the production of oligosaccharides containing 2,3,6-trideoxypyranoglycoside is reported. The key event is the Pd-catalyzed asymmetric diastereoselective hydroalkoxylation of ene-alkoxyallene-linked glycosidic fragments. The utility of this approach was demonstrated by the activation-free, stereodivergent, and convergent synthesis of various 2-deoxyoligosaccharides, as well as their aglycon conjugates.

Lewis-acid assisted cross metathesis of acrylonitrile with functionalized olefins catalyzed by phosphine-free ruthenium carbene complex

The exchange of the PPh3 ligand in the complex [1,3-bis(2,6-dimethylphenyl)4,5-dihydroimidazol-2-ylidene](PPh 3)-(Cl)2Ru=CHPh (7) for a pyridine ligand at ambient temperature leads to the formation of the stable phosphine-free carbene ruthenium complex [1,3-bis(2,6-dimethylphenyl)4,5-dihydroimidazol-2-ylidene] (C5H5N)2(Cl)2 Ru=CHPh (8). The resulted ruthenium complex exhibits highly catalytic activity for the cross metathesis of acrylonitrile with various functionalized olefins under mild conditions, and its activity can be further improved by the addition of a Lewis acid such as Ti(O?Pr)4. In the mixture products, the Z-isomer predominates. The Royal Society of Chemistry 2005.

Synthesis of pyrimidine-modified NHC ruthenium-alkylidene catalysts and their application in RCM, CM, em and ROMP reactions

A new type of N-heterocyclic carbene bearing ruthenium olefin metathesis catalyst was prepared through the incorporation of a chelated pyrimidinyl methylene subunit, in which electron-rich substituents were attached to stabilize the ruthenium complexes. These catalysts were successfully used in various types of olefin metathesis reactions, including ring-closing metathesis (RCM), cross-metathesis (CM), enyne metathesis (EM), and ring-opening metathesis polymerization (ROMP) reactions. The results therein showed that the presence of an electron-deficient pyrimidine structure greatly enhanced the new NHC ruthenium complexes’ catalytic activities. New N-heterocyclic carbene bearing ruthenium olefin metathesis catalysts were synthesized and applied in various types of olefin metathesis reactions, including ring-closing metathesis, cross-metathesis, enyne metathesis, and ring-opening metathesis polymerization reactions.

Ruthenium-diimine type complex as well as preparation method and application thereof

The invention relates to a ruthenium-diimine type complex as well as a preparation method and application thereof. The method comprises the following steps: i, dissolving 2-pyridine carboxaldehyde and2-aminochrysene into absolute ethyl alcohol, and heating and stirring under the protection of nitrogen gas; adding a ruthenium complex precursor Ru(bpy)2Cl2; heating and refluxing overnight under theprotection of the nitrogen gas; after raw materials are completely transformed, stopping heating; cooling to room temperature and concentrating; adding a methanol saturated solution of ammonium hexafluorophosphate into a concentrated solution; transferring a reaction mixture into a sand plate funnel for suction filtration, and washing; dissolving a crude product into acetone and taking n-hexane as a dispersion agent for recrystallizing, so as to obtain a ruthenium-diimine type complex pure product. The ruthenium-diimine type complex provided by the invention has the advantages of simple preparation method and relatively high yield and purity; after a ligand is synthesized, the ligand does not need to be subjected to separation treatment and can directly react with a ruthenium precursor toobtain a target product. The ruthenium-diimine type coordination complex has a wide application prospect in the fields including catalysis, sensing, molecular recognition and the like.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Product Details of 15746-57-3, you can also check out more blogs about15746-57-3

Nanoscale Metal?Organic Layers for Deeply Penetrating X-ray-Induced Photodynamic Therapy

We report the rational design of metal?organic layers (MOLs) that are built from [Hf6O4(OH)4(HCO2)6] secondary building units (SBUs) and Ir[bpy(ppy)2]+- or [Ru(bpy)3]2+-derived tricarboxylate ligands (Hf-BPY-Ir or Hf-BPY-Ru; bpy=2,2?-bipyridine, ppy=2-phenylpyridine) and their applications in X-ray-induced photodynamic therapy (X-PDT) of colon cancer. Heavy Hf atoms in the SBUs efficiently absorb X-rays and transfer energy to Ir[bpy(ppy)2]+ or [Ru(bpy)3]2+ moieties to induce PDT by generating reactive oxygen species (ROS). The ability of X-rays to penetrate deeply into tissue and efficient ROS diffusion through ultrathin 2D MOLs (ca. 1.2 nm) enable highly effective X-PDT to afford superb anticancer efficacy.

A new route to vitamin E Key-intermediates by olefin cross-metathesis

Ru-Catalyzed olefin cross-metathesis (CM) has been successfully applied to the synthesis of several phytyl derivatives (2b, 2d-f, 3b) with a trisubstituted C=C bond, as useful intermediates for an alternative route to alpha-tocopheryl acetate (vitamin E acetate; 1b) (Scheme 1). Using the second-generation Grubbs catalyst RuCl2(C21H 26N2)(CHPh)PCy3, (Cy = cyclohexyl; 4a) and Hoveyda-Grubbs catalyst RuCl2(C21H26N 2){CH-C6H4(O-iPr)-2} (4b), the reactions were performed with various C-allyl (5a-f, 7a,b) and O-allyl (8a-d) derivatives of trimethylhydroquinone-1-acetate as substrates. 2,6,10,14-Tetramethylpentadec-1-ene (6a) and derivatives 6c-e of phytol (6b) as well as phytal (6f) were employed as olefin partners for the CM reactions (Schemes 2 and 5). The vitamin E precursors could be prepared in up to 83% isolated yield as (E/Z)-mixtures.
