Asymmetric hydrogenation of ketones using Ir(III) complexes of N-alkyl-N’-tosyl-1,2-ethanediamine ligands

The combination of an enantiomerically pure N?-alkylated derivative of N-4-toluenesulfonyl-1,2-diphenylethane-1,2-diamine (TsDPEN) with iridium trichloride results in the formation of a catalyst with high selectivity for ketone hydrogenation. Products with enantiomeric excesses of up to 84% were formed. The best results were obtained using a ligand with an n-alkyl chain and ortho-substituted acetophenone derivatives and other hindered derivatives.

Application of ruthenium complexes of triazole-containing tridentate ligands to asymmetric transfer hydrogenation of ketones

The synthesis of a series of tridentate ligands based on a homochiral 1,2-diamine structure attached to a triazole group and their subsequent applications to the asymmetric transfer hydrogenation of ketones are described. In the best cases, alcohols of up to 93% ee were obtained. Although base is not required, the use of Ru3(CO)12 as metal source is essential, indicating a unique mechanism for the formation of the active catalyst.

POST CMP CLEANING COMPOSITION

The disclosure generally relates to a composition and process for cleaning residue and/or contaminants from microelectronic devices having said residue and contaminants thereon. The residue may include post-CMP, post-etch, and/or post-ash residue. The compositions and methods are particularly advantageous when cleaning a microelectronic surface comprising copper, low-k dielectric materials, and barrier materials comprising at least one of tantalum-containing material, cobalt-containing material, tantalum-containing, tungsten-containing, and ruthenium-containing material.

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.Recommanded Product: 1120-02-1, you can also check out more blogs about1120-02-1

Development of a pharmacophore for inhibition of human liver cytochrome P- 450 2D6: Molecular modeling and inhibition studies

To gain insight into the specificity of cytochrome P-450 2D6 toward inhibitors, a preliminary pharmacophore model was built up using strong competitive inhibitors. Ajmalicine (1), the strongest inhibitor known (K(i) = 3 nM) was selected as template because of its rigid structure. The preliminary pharmacophore model was validated by performing inhibition studies with derivatives of ajmalicine (1) and quinidine (9). Bufuralol (18) was chosen as substrate and the metabolite 1′-hydroxybufuralol (19) was separated by high performance liquid chromatography. All incubations were carried out using human liver microsomes after demonstration that the K(i) values obtained with microsomes were in accordance with those obtained with a reconstituted monooxygenase system containing purified cytochrome P-450 2D6. Large differences of K(i) values ranging between 0.005 and 100 muM were observed. Low-energy conformers of tested compounds were fit within the preliminary pharmacophore model. The analysis of steric and electronic properties of these compounds led to the definition of a final pharmacophore model. Characteristic properties are a positive charge on a nitrogen atom and a flat hydrophobic region, the plane of which is almost perpendicular to the N-H axis and maximally extends up to a distance of 7.5 A from the nitrogen atom. Compounds with high inhibitory potency had additional functional groups with negative molecular electrostatic potential and hydrogen bond acceptor properties on the opposite side at respective distances of 4.8-5.5 A and 6.6-7.5 A from the nitrogen atom. The superposition of strong and weak inhibitors led to the definition of an excluded volume map. Compounds that required additional space were not inhibitors. This is apparently the first pharmacophore model for inhibitors of a cytochrome P-450 enzyme and offers the opportunity to classify compounds according to their potency of inhibition. Adverse drug interactions which occur when both substrates and inhibitors of cytochrome P-450 2D6 are applied may be predicted.

Development and applications of an inexpensive and modular medium-throughput microcrystalliser for the preparation and characterisation of solid phases

Identification, isolation, and control of solid form are important for process and product control of specialty chemicals and pharmaceutical compounds. Solid forms are commonly isolated by crystallisation from solution and as a consequence acquisition of both phase equilibrium and kinetic information is vital. In these cases, control of solid form requires a complete assessment of the relationship between crystallisation conditions and both structural and physical aspects of solid form through a number of experiments which may run into many hundreds for complex systems. Traditionally such experiments have been completed sequentially. To fully characterise complex systems in this manner often takes years and so to accelerate this process and characterise a wider phase space, tools for studying multiple samples have been developed to increase throughput. These high-throughput synthetic and analytical techniques are often prohibitively expensive for smaller-scale research laboratories. As a solution to this problem, we have developed a low cost (<4000 GBP) and modular medium-throughput microcrystalliser and optical tomography system for acquisition of phase equilibria, crystallisation kinetic, and solid-form data on organic materials. The design and typical applications of this equipment are presented here.

Application of capillary electrophoretic methods for the analysis of plant phloem and xylem saps composition: A review

Plant vascular tissue is essential for the exchange of water, nutrients, metabolic products, and signals among distant organs in cormophytes. The compositions of phloem and xylem saps are highly dependent on many internal and external factors, and thus their analysis provides a valuable insight into plant physiology, growth, and development as well as nutrition status or presence of biotic or abiotic stresses. Capillary electrophoresis characterized by highly efficient separations and minuscule sample requirements represents a suitable analytical technique for this purpose because the sap constitutes a complex mixture with generally minimal availability. This review aims at providing a comprehensive overview of published capillary electrophoretic methods for the analysis of primary components present in the phloem and xylem saps of higher plants.
