Urrego, Maria Isabel Gonzalez published the artcileDietary protein sources and their effects on faecal odour and the composition of volatile organic compounds in faeces of French Bulldogs, Name: 4-Hydroxy-3-tert-butylanisole, the main research area is feces odor dietary protein volatile organic compound; canine; indole; malodorous compounds; phenol.

The strong odor of faeces and excessive production of gases in some dog breeds have long been a concern of owners. The pet food industry uses nutritional alternatives, such as high-quality ingredients and additives, to improve the odor of faeces. However, there are still some dog breeds, such as the French Bulldog, that present this problem due to the presence into the large intestine of indigested protein. Therefore, a deeper understanding of the volatile compounds that influence the odor of dog faeces is important. This study aimed to identify changes of faecal odor compounds that are most prevalent in French Bulldogs based on food containing different high-quality protein sources and their effect in sensory anal. Four maintenance foods with different protein sources were formulated: P, poultry meal food; W, wheat gluten food; PW, poultry meal and wheat gluten food; and PWH, poultry meal, wheat gluten, and hydrolyzed protein food. Eight adult French Bulldogs were arranged in a 4×4 Latin square design and adapted to foods for 28 days. Fresh faeces were collected for anal. of volatile organic compounds (VOCs) and sensory anal. The means were compared by SAS, and statistical significance was indicated by p ≤ 0.05. No adverse effects were observed in the animals regarding VOCs, and a significant difference was observed in two of the 68 compounds identified. The animals fed a P food had higher concentrations of phenol in the faeces, whereas the indole compound was present at higher concentrations in animals fed the W food. P food was associated with higher odor perception during sensory evaluation. In summary, the source of protein in the foods had little impact on the composition of VOCs, and a greater perception of the odor was determined by sensory anal. when foods containing animal protein were administered.

Palvoelgyi, Adam Mark published the artcileCounterion-Enhanced Pd/Enamine Catalysis: Direct Asymmetric α-Allylation of Aldehydes with Allylic Alcohols by Chiral Amines and Achiral or Racemic Phosphoric Acids, Product Details of C11H16O2, the main research area is aldehyde allyl alc palladium phosphoric acid amine chiral allylation; enal stereoselective preparation.

We report a straightforward and efficient Pd/enamine catalytic procedure for the direct asym. α-allylation of branched aldehydes. The use of simple chiral amines and easily prepared achiral or racemic phosphoric acids, together with a suitable Pd-source resulted in a highly active and enantioselective catalyst system for the allylation of various α-branched aldehydes with different allylic alcs. The reported procedure could provide an easy access to both product antipodes. Furthermore, two possible orthogonal derivatizations of the enantioenriched aldehydes were performed without any decrease in enantioselectivity.

De Smet, Gilles published the artcileSelective Nickel-Catalyzed Hydrodeacetoxylation of Aryl Acetates, Related Products of ethers-buliding-blocks, the main research area is aromatic alc magnesium catalyst acetoxylation; aryl acetate preparation nickel catalyst chemoselective hydrodeacetoxylation green chem; anisole preparation; Aryl Acetates; C−O Bond Activation; Hydrodeacetoxylation; Nickel Catalysis; Renewable Resources.

Ni-catalyzed hydrodeacetoxylation of aryl acetates (Ar-OAc) with HBpin in a green carbonate solvent selectively delivered the corresponding deoxygenated arenes (ArH). The method was also applicable to highly challenging guaiacyl and syringyl acetates, leaving -OMe groups intact without arene reduction Renewable 4-propylguaiacol obtained from pine could also be transformed without significant loss in yield vs. oil derived feedstock. The observed chemoselectivity for Ar-OAc vs. ArO-Ac bond cleavage was rationalized based on mechanistic experiments and DFT calculations ArOH side-product formation was attributed to direct competitive Ni-catalyzed reduction of the C=O bond. Hydrodeacyloxylation of a set of aryl alkanoates featured interesting chemoselectivity with a dramatic influence of the length and structure of the alkyl chain on catalysis.

An efficient electrooxidative double C-H/C-H coupling of phenols with 3-phenylbenzothiophene has been developed under external oxidant- and catalyst-free conditions. This strategy could enable the highly tunable access to benzothiophene derivatives and exhibited broad substrate generality under mild conditions. The reaction is likely to proceed via the cross-coupling of the p-methoxylphenol radical and the 3-phenylbenzothiophene radical cation.

Cai, Shou-Le published the artcileNHC Ligand-Enabled, Palladium-Catalyzed Non-Directed C(sp3)-H Carbonylation To Access Indanone Cores, Recommanded Product: 4-Hydroxy-3-tert-butylanisole, the main research area is indanone preparation NHC ligand palladium catalyst; aryl triflate bromide carbon monoxide carbonylation.

A palladium-catalyzed C(sp3)-H carbonylation of alkylated aryl triflates or bromides I (R1 = 6-C6H5, 6-CH3CO, 6-CO2CH3, etc.; R2 = CH3, CO2CH3, CH2CH3, etc.; X = Br, OTf, ONf) under 1 atm of CO has been developed, in which no directing group or oxidant was required. The essence of this reaction is the combination of appropriate NHC ligands with palladium to facilitate the formation of the five-membered cyclopalladium intermediate. Mechanism studies suggest that the insertion of carbon monoxide into two five-membered cyclopalladium species generated via palladium migration might be the crucial step for this transformation. This method offers an efficient solution for expedient construction of indanone cores II (R1 = 6-C6H5, 6-CH3CO, 6-CO2CH3, etc.; R2 = CH3, CO2CH3, CH2CH3, etc.) which are valuable synthons and pharmacophores ubiquitously found in numerous natural products.

A metal-free, oxidative coupling of phenols with various nucleophiles, including arenes, 1,3-diketones and other phenols was reported. Cross-coupling was mediated by a sulfoxide which inverts the reactivity of the phenol partner. Crucially, the process showed high selectivity for cross-vs. homo-coupling and allowed efficient access to a variety of aromatic scaffolds including biaryls, benzofurans and through an iterative procedure aromatic oligomers.

Zhang, Junhui published the artcileComparative (co-)pyrolytic performances and by-products of textile dyeing sludge and cattle manure: Deeper insights from Py-GC/MS, TG-FTIR, 2D-COS and PCA analyses, Category: ethers-buliding-blocks, the main research area is kinetic copyrolysis gas char textile dyeing sludge cattle manure; Cattle manure; Char functional groups; Gaseous products; Kinetics; Textile dyeing sludge.

Not only does pyrolysis recover energy and value-added byproducts but also reduces waste stream volume The low volatiles and high ash contents of textile dyeing sludge (TDS) limit its mono-pyrolysis performance. This study aimed to conduct an in-depth anal. of its co-pyrolytic performance with cattle manure (CM). The co-pyrolysis enhanced the volatiles emission from the early devolatilization stage whose reaction mechanism shifted from a diffusion model to a reaction-order model. The further cracking of macromol. materials was mainly elucidated by the reaction-order model. The temperature dependency of the co-pyrolytic gases was of the following order: aliphatic hydrocarbons > CO2 > alcs., phenols, ethers, aldehydes, ketones, and carboxylic acids. The main co-pyrolytic volatile products were coumaran and 4-vinylguaiacol. The relative content of guaiacol-type components could be enhanced by co-pyrolysis and lowering the operational temperature to 450°C. The interaction of co-pyrolysis enriched the char aromaticity. Our findings provide practical insights into the control and application opportunities and limitations on the high value-added energy and products from the co-pyrolysis of TDS and CM.

Niederer, Kyle A. published the artcileOxidative photocatalytic homo- and cross-coupling of phenols: Nonenzymatic, catalytic method for coupling tyrosine, Quality Control of 121-00-6, the main research area is phenol homo cross coupling oxidative photocatalytic method safety eyewear; oxidation potential nucleophilicity homo cross coupling reaction mechanism; tyrosine coupling cyclic voltammetry fluorescence quenching crystal structure; Oxidative coupling; cross-coupling; phenol coupling; photocatalysis; tyrosine dimerization.

An oxidative photocatalytic method for phenol-phenol homo- and cross-coupling is described, and isolated yields of 16-97% are obtained. Measured oxidation potentials and computed nucleophilicity parameters support a mechanism of nucleophilic attack of one partner onto the oxidized neutral radical form of the other partner. Our understanding of this model permitted the development of cross-coupling reactions between nucleophilic phenols/arenes and easily oxidized phenols with high selectivity and efficiency. A highlight of this method is that one equivalent of each coupling partner is utilized. Building on these findings, a nonenzymic, catalytic method for coupling tyrosine was also developed. Due to the high intensity of the light source it is highly recommended that impact resistant sunglasses be worn when placing a reaction in the photochem. bay.
