Palladium Iodide Catalyzed Multicomponent Carbonylative Synthesis of 2-(4-Acylfuran-2-yl)acetamides

Molecules, 2023
2-Propargyl-1,3-dicarbonyl compounds have been carbonylated under oxidative conditions and with the catalysis of the PdI2/KI catalytic system to selectively afford previously unreported 2-(4-acylfuran-2-yl)acetamides in fair to good yields (54–81%) over ...

One‐Pot Biphasic Photocatalytic CO2‐to‐Carbonylation Cascades

Angewandte Chemie, EarlyView.
Bioinspired biphasic compartmentalization enables one‐pot cascades where photocatalytic CO2 reduction generates CO for carbonylative cross‐couplings to synthesize complex organic products, including a pharmaceutical. ABSTRACT Photosynthesis compartmentalizes reactions across the thylakoid membrane in vivo to upcycle CO2 into complex chemicals that are ...

Carbonylation of Phenylacetylene by Rhodium Carbonyl Chloride [PDF]

Bulletin of the Chemical Society of Japan, 1974
Abstract The reaction of phenylacetylene with carbon monoxide catalyzed by rhodium carbonyl chloride (Rh2(CO)4Cl2) gives 3,6 diphenyl-1-oxa-[3,3,0] bicycloocta-3,6-diene-2,4-dione.

Nature of Amide Carbonyl−Carbonyl Interactions in Proteins

Journal of the American Chemical Society, 2009
Noncovalent interactions define and modulate biomolecular structure, function, and dynamics. In many protein secondary structures, an intimate interaction exists between adjacent carbonyl groups of the main-chain amide bonds. As this short contact contributes to the energetics of protein conformational stability as well as protein-ligand interactions ...

Histone Carbonylation Is a Redox-Regulated Epigenomic Mark That Accumulates with Obesity and Aging

Antioxidants, 2020
Oxidative stress is a hallmark of metabolic disease, though the mechanisms that define this link are not fully understood. Irreversible modification of proteins by reactive lipid aldehydes (protein carbonylation) is a major consequence of oxidative ...

Effect of Cyclic Heat Exposure on the Growth Performance and Metabolism of Broilers Fed Palm Kernel Meal

Animal Research and One Health, EarlyView.
The aim of our study is to evaluate the interaction between HS and the incorporation of PKM in broiler chicken diets, as well as its effect on growth performance and metabolism. Based on the results obtained, PKM supplementation failed to mitigate the adverse effects of heat stress in broiler chickens. ABSTRACT The aim of this study was to evaluate the

Ir Complexes With Mixed‐Valent Bidentate Ligands: From Complex Synthesis to Catalytic Application

Chemistry – A European Journal, EarlyView.
ABSTRACT The bidentate ligands Ph2P(E)NHPPh2 (E = S, Se) feature phosphorous atoms in two different oxidation states and provide the potential to tune chemical reactivity through the choice of donor E. The mononuclear complexes [Ir(COD){κ2‐P,E‐Ph2P(E)NPPh2}] (E = S 1a, Se 1b) were prepared from the dimer [IrClCOD]2 (COD = 1,5‐cyclooctadiene) and the ...
