Ai, Han-Jun; Wang, Hai; Li, Chong-Liang; Wu, Xiao-Feng published the artcile< Rhodium-Catalyzed Carbonylative Coupling of Alkyl Halides with Phenols under Low CO Pressure>, Reference of 699-12-7, the main research area is rhodium catalyst carbonylative coupling alkyl halide phenol carbon monoxide.

A rhodium-catalyzed carbonylative transformation of alkyl halides under low pressure of CO has been developed. This robust catalyst system allows using phenols as the carbonylative coupling partner and, meanwhile, exhibits high functional group tolerance and good chemoselectivity. Substrates even with a large steric hindrance group or multiple reaction sites can be selectively converted into the desired products in good to excellent yields. A gram-scale experiment was performed and delivered an almost quant. amount of the product. Control experiments were performed as well, and a possible reaction mechanism is proposed.

Cai, Aijie; Yan, Wenhao; Wang, Chao; Liu, Wei published the artcile< Copper-Catalyzed Difluoromethylation of Alkyl Iodides Enabled by Aryl Radical Activation of Carbon-Iodine Bonds>, Quality Control of 167938-56-9, the main research area is alkyl iodide copper catalyst difluoromethylation; alkyldifluoromethane preparation; copper; cross-coupling; difluoromethylation; radicals; reaction mechanisms.

A novel strategy that leveraged the halogen abstraction ability of aryl radicals, thereby engaging a diverse range of alkyl iodides in copper-catalyzed Negishi-type cross-coupling reactions at room temperature Specifically, aryl radicals generated via copper catalysis efficiently initiate the cleavage of the carbon-iodide bonds of alkyl iodides. The alkyl radicals thus generated enter the copper catalytic cycles to couple with a difluoromethyl zinc reagent, thus furnished the alkyl difluoromethane products. This unprecedented Negishi-type difluoromethylation approach was applied to the late-stage modification of densely functionalized pharmaceutical agents and natural products.

Ballesteros-Soberanas, Jordi; Hernandez-Garrido, Juan Carlos; Ceron-Carrasco, Jose Pedro; Leyva-Perez, Antonio published the artcile< Selective semi-hydrogenation of internal alkynes catalyzed by Pd-CaCO3 clusters>, COA of Formula: C4H8O, the main research area is alkene preparation; internal alkyne selective semi hydrogenation palladium catalyst.

The de-novo synthesis of soluble or solid-supported Pd-(CaCO3)n clusters (n = 2-13) and their high catalytic activity for the semi-hydrogenation of internal alkynes compared to terminal alkynes, was presented. Mechanistic studies showed that this reactivity, i.e. internal alkynes more reactive than terminal alkynes, came from the higher electrophilicity of the Pd-(CaCO3)n cluster compared to the nanoparticulated Lindlar catalyst, which unveils the advantages of isolating the min. catalytic unit of a solid catalyst. Translating solid active sites into soluble catalysts turns around the classical approach and constitutes a paradigmatic shift in catalyst design.

Yeh, Nai-Hua; Krueger, Ruby; Moeller, Kevin D. published the artcile< Microelectrode Arrays, Dihydroxylation, and the Development of an Orthogonal Safety-Catch Linker>, Recommanded Product: But-3-en-1-ol, the main research area is microelectrode array dihydroxylation orthogonal safety catch linker.

Construction of larger mol. libraries on an addressable microelectrode array requires a method for recovering and characterizing mols. from the surface of any electrode in the array. This method must be orthogonal to the synthetic strategies needed to build the array. The authors report here a method for achieving this goal that employs the site-selective dihydroxylation reaction of a simple olefin.

Maneikyte, Juste; Bausys, Augustinas; Leber, Bettina; Feldbacher, Nicole; Hoefler, Gerald; Kolb-Lenz, Dagmar; Strupas, Kestutis; Stiegler, Philipp; Schemmer, Peter published the artcile< Dietary glycine prevents FOLFOXchemotherapy-induced heart injury: a colorectal cancer liver metastasis treatment model in rats>, Computed Properties of 1492-18-8, the main research area is colorectal cancer heart injury glycine collagen type I Hb; FOLFOX; cardiotoxicity; colorectal cancer; glycine.

This study tested the hypothesis of glycine being cardioprotective in a rat model of FOLFOX in combination with CRLM. Materials and Methods: The effect of glycine was tested in vitro on human cardiac myocytes (HCMs). To test glycine in vivo Wag/Rij rats with induced CRLM were treated with FOLFOX ±5% dietary glycine. Left ventricle ejection fraction (LVEF), myocardial fibrosis, and apoptosis, also heart fatty acid binding protein (h-FABP) and brain natriuretic peptide levels were monitored. PCR anal. for Collagen type I, II, and brain natriuretic peptide (BNP) in the heart muscle was performed. Results: In vitro glycine had no effect on HCM cell viability. Treatment with FOLFOX resulted in a significant increase of h-FABP levels, increased myocardial fibrosis, and apoptosis as well as increased expression of type I Collagen. Furthermore, FOLFOX caused a decrease of LVEF by 10% (p = 0.028). Dietary glycine prevented FOLFOX-induced myocardial injury by preserving the LVEF and reducing the levels of fibrosis (p = 0.012) and apoptosis (p = 0.015) in vivo. Conclusions: Data presented here demonstrate for the first time that dietary glycine protects the heart against FOLFOX-induced injury during treatment for CRLM.

Chakraborty, Gargi; Sikari, Rina; Mondal, Rakesh; Mandal, Sutanuva; Paul, Nanda D. published the artcile< Nickel-Catalyzed Synthesis of Pyrimidines via Dehydrogenative Functionalization of Alcohols>, Application of C8H9FO, the main research area is pyrimidine preparation; alc amidine multicomponent dehydrogenative coupling nickel catalyst.

Herein, a comparative study of nickel-catalyzed syntheses of pyrimidines via dehydrogenative multi-component coupling of alcs. and amidines using two different classes of nickel catalysts differing with respect to their mode of action during catalysis is reported. The catalysts are either two tetracoordinate Ni(II)-complexes containing two apparently redox-inactive tetraaza macrocyclic ligands or square planar Ni(II)-complexes featuring redox-active diiminosemiquinonato type scaffolds. Tetracoordinate Ni(II) catalysts dehydrogenate alcs. via a two-electron hydride transfer pathway involving energetically demanding nickel-centered redox events while in the presence of square planar Ni(II)-complexes dehydrogenation of alcs. proceeds via a one-electron hydrogen atom transfer (HAT) pathway via synergistic participation of metal and ligand centered redox processes avoiding high energy nickel centered redox events. Detailed substrate screening and control experiments were performed to unveil the reaction sequence and understand the advantages/disadvantages of these two pathways.

Ghlissi, Zohra; Kallel, Rim; Krichen, Fatma; Hakim, Ahmed; Zeghal, Khaled; Boudawara, Tahiya; Bougatef, Ali; Sahnoun, Zouheir published the artcile< Polysaccharide from Pimpinella anisum seeds: Structural characterization, anti-inflammatory and laser burn wound healing in mice>, Name: (2S,3R,4S,5S,6R)-6-(Hydroxymethyl)tetrahydro-2H-pyran-2,3,4,5-tetraol, the main research area is Staphylococcus Pimpinella laser burn wound healing seed polysaccharide antiinflammatory; Anti-inflammatory activity; Laser burn; Pimpinella anisum; Polysaccharide; Wound healing.

The polysaccharide preparation from Pimpinella anisum seeds (PAP) was isolated and characterized to evaluate its laser burn wound-healing and anti-inflammatory activities in mice. The structure characterization of PAP by Infra-red spectrometry (IR), NMR (NMR), Gas chromatogram-Mass spectrometer (GC-MS) and colorimetric methods revealed an optimum yield of 8.84%, a high quantity of carbohydrate (64.75%) and low levels of lipids, protein and sulfate. Galactose (33.47%), β-D-Glucose (26.71%) and a-D-Mannose (18.21%) were the major monosaccharides components presenting in PAP, and a smaller amounts of β-D-Galactose, D-Fructose, a-D-Glucose, a-L-Galactose and arabinose were detected. PAP showed noticeable antioxidant and antibacterial properties. The anti-inflammatory activity of PAP in the carrageenan-induced paw edema model in mice, demonstrated by reduced edema and cellular infiltration, and oxidative stress markers in muscle tissue. A beneficial wound healing effect was also revealed. The topical application of PAP based gel on laser burn lesions accelerates wound contraction, the re-epithelization and remodeling phases after seven days of treatment. The results demonstrated that PAP is a novel promising source of natural wound healing and anti-inflammatory drugs. The high content and varied PAP monosaccharides seem to be responsible for the observed biol. activities.
