A formal enantioselective synthesis of nectrisine, a potent alpha-glucosidase inhibitor, was carried out starting from butadiene monoepoxide through a synthetic sequence involving enantioselective allylic substitution, cross-metathesis, dihydroxylation, and cyclization.

The reactant in an enzyme-catalyzed reaction is called a substrate. Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction.I hope my blog about 301224-40-8 is helpful to your research., Product Details of 301224-40-8

Synthetic Route of 37366-09-9. Let’s face it, organic chemistry can seem difficult to learn. Especially from a beginner’s point of view. Like 37366-09-9, Name is Dichloro(benzene)ruthenium(II) dimer. In a document type is Article, introducing its new discovery.

A series of 3-oxoglutaric acid derivatives have been hydrogenated in different solvents in the presence of [RuCl(benzene)(S)-SunPhos]Cl (SunPhos=(2,2,2?,2?-tetramethyl-[4,4?-bibenzo[d][1,3]dioxole] -5,5?-diyl)bis(diphenylphosphine)). Unlike simple beta-keto acid derivatives, these advanced analogues can be readily hydrogenated in uncommon solvents such as THF, CH2Cl2, acetone, and dioxane with high enantioselectivities. Two possible catalytic cycles have been proposed to explain the different reactivities of these 1,3,5-tricarbonyl substrates in the tested solvents. The C-2 and C-4 substituents had notable but irregular influence on the reactivity and enantioselectivity of the reactions. More pronounced solvent effects were observed: the ee values increased from around 20 % in EtOH or THF to 90 % in acetone. Inversion of the product configuration was observed when the solvent was changed from EtOH to THF or acetone, and a mixed solvent system can lead to better enantioselectivity than a single solvent. Pronounced solvent effects: 3-Oxoglutaric acid derivatives have been hydrogenated in various solvents with high enantioselectivities (see scheme). Inversions of the product configuration were observed when the solvent was changed. Mixed solvent systems can give better enantioselectivities than a single solvent.

37366-09-9, Name is Dichloro(benzene)ruthenium(II) dimer, molecular formula is C12H12Cl4Ru2, belongs to ruthenium-catalysts compound, is a common compound. In a patnet, once mentioned the new application about 37366-09-9, name: Dichloro(benzene)ruthenium(II) dimer

Here, the synthesis of a RuII photocatalyst by light-directed oligonucleotide-templated ligation reaction is described. The photocatalyst was found to have tremendous potential for signal amplification with >15000 turnovers measured in 9 hours. A templated reaction was used to turn on the activity of this ruthenium(II) photocatalyst in response to a specific DNA sequence. The photocatalysis of the ruthenium(II) complex was harnessed to uncage a new precipitating dye that is highly fluorescent and photostable in the solid state. This reaction was used to discriminate between different DNA analytes based on localization of the precipitate as well as for in cellulo miRNA detection. Finally, a bipyridine ligand functionalized with two different peptide nucleic acid (PNA) sequences was shown to enable template-mediated ligation (turn on of the ruthenium(II) photocatalysis) and recruitment of substrate for templated photocatalysis.

The present invention describes the use of soluble metal salts to reduce impurities and metathesis catalysts poisons from olefinic feedstocks to improve olefin metathesis efficiency. The soluble metal salts were added to the olefinic feedstocks to prevent peroxides and catalyst poisons from inhibiting the metathesis catalyst. The soluble metal salts remain in the olefinic feedstocks and are used without further purification in the olefin metathesis reactions. The key to this invention is the soluble metal salt compounds do not inhibit the olefin metathesis catalysts but unexpectedly increase olefin metathesis catalyst efficiency while prior art heterogeneous metal complexes sequester the olefin metathesis catalyst, preventing olefin metathesis.

N-heterocyclic carbene (NHC) based ruthenium complexes were studied as catalysts for the transfer hydrogenation of ketones. Variations in the catalyst structure were investigated for their impact on hydrogenation and catalyst stability. Catalyst attributes included bis- or mono-NHC ligands, pendant ether groups in some cases, and arene ligands of varied bulk and donor strength. Ruthenium complexes were synthesized and fully characterized, including complexes with a monodentate NHC ligand containing a tethered ether N substituent (ImEt,CH2CH2OEtRuCl2(eta6-arene); arene = benzene (4), p-cymene (5), hexamethylbenzene (6)), a complex with a monodentate NHC ligand with solely alkyl N substituents (Im Et,PentylRuCl2(eta6-p-cymene) (8)), and a complex with a bis-NHC ligand ([RuCl(methylenebis(ImEt) 2)(eta6-p-cymene)]PF6 (7)) (Im = imidazole-derived NHC; superscripts indicate N substituents). X-ray crystal structures were obtained for 4, 5, 7, and 8. All of the ruthenium complexes were tested and found to be active transfer hydrogenation catalysts for the reduction of acetophenone to 1-phenylethanol in basic 2-propanol. Precatalyst 4, which contains a tethered ether group and benzene ligand, was found to be the most active catalyst. Variable-temperature 1H NMR studies of complexes 4-6 show that arene lability increases in the order C 6Me6 < cymene < benzene, and this lability is directly correlated with catalytic activity. The catalysis appears to be homogeneous, and a mechanism invoking arene loss is proposed. Precatalyst 4 reduced electron-deficient ketones most easily, and 4?-nitroacetophenone was reduced under base-free conditions. The highest TOF (turnover frequency) and TON (turnover number) values obtained were 3003 h-1 and 845, respectively, for ketone reduction with catalyst 4. Do you like my blog?
