Direct C(sp3)-H functionalization of alkyl nitriles is a low toxic and facile route to nitrile-containing compounds. In this research, the Ag2CO3-mediated nitrile methylenation of enol acetates is developed to prepare gamma-ketonitriles through the direct C(sp(3))-H oxidative functionalization of acetonitrile. A radical pathway is proposed, and acetonitrile serves both as solvent and CN-containing radical source. (C) 2019 Elsevier Ltd. All rights reserved.

In this contribution, a protocol was established for the selective catalytic hydrogenation of nitroarenes to the correspondingN-arylhydroxylamines. The reduction of 1-(4-chlorophenyl)-3-((2-nitrobenzyl)oxy)-1H-pyrazole, an intermediate in the synthesis of the antifungal reagent pyraclostrobin that includes carbon-chlorine bonds, benzyl groups, carbon-carbon double bonds and other structures that are easily reduced, was chosen as the model reaction for catalyst evaluation and condition optimization. Extensive passivant evaluation showed that RANEY (R)-nickel treated with ammonia/DMSO (1 : 10, v/v) afforded the optimal result, especially with a particle size of 400-500 mesh. To combine the modified catalyst with continuous-flow reaction technology, the reaction was conducted at room temperature, rendering the desired product with a conversion rate of 99.4% and a selectivity of 99.8%. The regeneration of catalytic activity was also studied, and an in-column strategy was developed by pumping the passivate liquid overnight. Finally, the generality of the method was explored, and 7 substrates were developed, most of which showed a good conversion rate and selectivity, indicating that the method has a certain degree of generality.

An efficient oxidation and functionalization of C-H bonds with an inorganic-ligand supported iron catalyst and hydrogen peroxide to prepare the corresponding ketones was achieved using the bromide ion as a promoter. Preliminary mechanistic investigations indicated that the bromide ion can bind to FeMo6 to form a supramolecular species (FeMo6 center dot 2Br), which can effectively catalyze the reaction.

Ketones are ubiquitous structural motifs in chemical materials and medicinally active pharmaceutical ingredients. Transition metal-catalyzed C-H bond functionalization is one of the most efficient tactics for diversification of ketones. Palladium-catalyzed C-H arylation of aliphatic and aromatic ketones has been achieved utilizing an inexpensive dipeptide as a transient directing group. The tridentate coordination used in this reaction enhances the reactivity of the substrates and allows reduction of the loading of the directing group compounds to 20%. This approach allows rapid arylation of complex natural products, medicinal-chemistry-related scaffolds, and even remote C(sp(2))-H bonds.

A copper-mediated domino condensation reaction of readily accessible oxime acetates with ninhydrin is reported to afford pyrrolo[2,1-a]isoindolediones via new C-C & C-N bond formations. A wide range of oxime acetates were shown to generally participate in the reaction to produce the condensed products in excellent yields. The necessary control experiments were performed and the mechanism is proposed to involve sequentially the formation of iminium radical via Cu-mediated N-O bond cleavage of oxime acetates, addition of the radical to ninhydrin and rearrangement via ring expansion.

Safety of 1-(4-Nitrophenyl)ethanone. I found the field of Chemistry very interesting. Saw the article Au(I)-Catalyzed Synthesis of Trisubstituted Indolizines from 2-Propargyloxypyridines and Methyl Ketones published in 2019.0, Reprint Addresses Anderson, CE (corresponding author), Calvin Coll, Dept Chem & Biochem, Grand Rapids, MI 49546 USA.. The CAS is 100-19-6. Through research, I have a further understanding and discovery of 1-(4-Nitrophenyl)ethanone.

A new Au(I)-catalyzed method for the preparation of trisubstituted indolizines from easily accessible 2-propargyloxy-pyridines is reported. The reaction tolerates a wide range of functionality, allowing for diversity to be introduced in four distinct regions of the product (R, R-1, R-2, and Ar). The proposed mechanism proceeds via enol addition to an allenamide intermediate and explains the observed increase in yields when electron poor methyl ketones are utilized.

The asymmetric direct reductive amination of prochiral ketones with aryl amines using 1-hydrosilatrane with a chiral Bronsted acid catalyst is reported. This is the first known example of chiral Bronsted acid-catalyzed asymmetric reductive amination using a silane as the hydride source. The reaction features a highly practical reducing reagent and proceeds efficiently at room temperature without a specialized reaction setup or equipment to exclude air or moisture. This method provides high conversion and enantiomeric excess up to 84% of the desired chiral secondary amines with minimal side products.

Background: Diabetes mellitus is the third-largest non-communicable chronic disease worldwide. There are many effective drugs, but the long-term use of these clinical drugs may cause various side effects. Therefore, it is urgent to develop new antidiabetic molecules with higher efficacy and lower toxicity. Methods: Fifteen new 3-aryl-1-(5-methylisoxazol-3-ylamino)-1-(4-nitrophenyl)propan-1-one were synthesized directly through the Mannich reaction of 4-nitroacetophenone, 3-amino-5-methylisoxazole and aromatic aldehydes catalyzed by concentrated hydrochloric acid. The molecular structures of the products were fully characterized by H-1 NMR, C-13 NMR, ESI MS and HRMS. The peroxisome proliferator-activated receptor (PPAR) response element and alpha-glucosidase inhibitory activity of these compounds were evaluated in vitro. Molecular docking, molecular physical parameters calculation, and molecular toxicity prediction were performed to analyze the structure-activity relationship and evaluate the druggability of these compounds theoretically. Results: All compounds exhibited weak antidiabetic activities, but compound 15 showed promising as a high performance, dual-target antidiabetic lead compound with peroxisome proliferator-activated receptor (PPAR) response element relative agonist activity of 99.55% at 27.2 nmol.ml(-1) and alpha-glucosidase inhibitory activity of 35.21% at 13.6 nmol.mL(-1). All compounds obtained may have no cardiotoxicity, no acute toxicity, no carcinogenic, and within safe range of mutagenic risk. Conclusion: This study identified a potential PPAR lead molecule and presented an unusual strategy for antidiabetic drug development.

Complex OsH6((PPr3)-Pr-i)(2) is an efficient catalyst precursor for the addition of pinacolborane and catecholborane to the C-N triple bond of alkyl nitrites. In this way, a variety of N,N-diborylamines have been isolated and fully characterized, including 13 derivatives not described so far. The range of nitrites used is wide and comprises substrates having unfunctionalized linear and branched chains, and functionalized chains with methoxide, trifluoromethyl, aryl, pyridyl, benzoyl, or cyanide groups. Kinetic studies demonstrate that the overall process consists of two consecutive irreversible reactions: the catalytic metal-promoted monohydroboration of the nitrile to afford the borylimine and the metal-free stoichiometric hydroboration of the latter to give the diborylamine. The mechanism of the hydroboration has been established by combining the kinetic analysis of the catalysis, stoichiometric reactions, and DFT calculations. The rate-determining step of the catalysis is the insertion of the C-N triple bond of the nitrite into the Os-B bond of an osmium-sigma-borane intermediate and is regiodirected by the nucleophilicity of the nitrogen atom and the electrophilicity of the carbon atom of the nitrite.
