This study describes diversity-oriented synthesis of 2,2,3-substituted-2,3-dihydroquinolin-4(1H)-ones vs. functionalised quinoline or N-alkenylindole derivatives through Bronsted acid mediated or Lewis acid catalyzed sequential reactions of 2-alkynylanilines with ketones. In particular, a series of challenging quinolin-4-one derivatives are prepared with good functional group tolerance in an atom-economical fashion by using p-toluenesulfonic acid monohydrate as a promoter of the reaction of ketones with 2-alkynylanilines in EtOH at reflux, while the same starting materials give the corresponding 4-substituted quinolines in toluene at 110 degrees C both in the presence of p-toluenesulfonic acid monohydrate as the promoter and FeCl3 as the catalyst. The divergent formation of N-alkenylindole derivatives occurs by switching to the use of ZnBr2 as the catalyst under the same reaction conditions. Conversely, only 4-methylsubstituted quinoline derivatives were isolated by reacting 2-ethynylanilines and/or 2-trimethylsylilanilines with ketones in all examined cases.

A nitrate-promoted Pd-catalysed mild cross-dehydrogenative C(sp(2))-H bond oxidation of oximes or azobenzenes with diverse carboxylic acids has been developed. In contrast to the previous catalytic systems, this protocol features mild conditions (close to room temperature for most cases) and a broad substrate scope (up to 64 examples), thus constituting a versatile method to directly prepare diverseO-aryl esters. Moreover, the superiority of the nitrate additive in this mild transformation was further determined by experimental and computational evidence.

I found the field of Chemistry very interesting. Saw the article N-Terminal Decarboxylation as a Probe for Intramolecular Contact Formation in gamma-Glu-(Pro)(n)-Met Peptides published in 2020.0. Computed Properties of C8H7NO3, Reprint Addresses Filipiak, P (corresponding author), Adam Mickiewicz Univ, Fac Chem, PL-61614 Poznan, Poland.; Filipiak, P (corresponding author), Adam Mickiewicz Univ, Ctr Adv Technol, PL-61614 Poznan, Poland..

The kinetics of intramolecular-contact formation between remote functional groups in peptides with restricted conformational flexibility were examined using designed peptides with variable-length proline bridges. As probes for this motion, free radicals were produced using the center dot OH-induced oxidation at the C-terminal methionine residue of gamma-Glu-(Pro)(n)-Met peptides (n = 0-3). The progress of the radicals’ motion along the proline bridges was monitored as the radicals underwent reactions along the peptides’ backbones. Of particular interest was the reaction between the sulfur atom located in the side chain of the oxidized Met residue and the unprotonated amino group of the glutamic acid moiety. Interactions between them were probed by the radiation-chemical yields (expressed as G values) of the formation of C-centered, alpha-aminoalkyl radicals (alpha N) on the Glu residue. These radicals were monitored directly or via their reaction with p-nitroacetophenone (PNAP) to generate the optically detected PNAP(center dot-) radical anions. The yields of these alpha N radicals were found to be linearly dependent on the number of Pro residues. A constant decrease by 0.09 mu M J(-1) per spacing Pro residue of the radiation-chemical yields of G(alpha N) was observed. Previous reports support the conclusion that the alpha N radicals in these cases would have to result from (S.*.N)(+)-bonded cyclic radical cations that arose as a result from direct contact between the ends of the peptides. Furthermore, by analogy with the rate constants for the formation of intramolecularly (S.*.S)(+)-bonded radical cations in Met-(Pro)-Met peptides (J. Phys. Chem. B 2016, 120, 9732), the rate constants for the formation of intramolecularly (S.*.N)(+)-bonded radical cations are activated to the same extent for all of the gamma-Glu-(Pro)(n)-Met peptides. Thus, the continuous decrease of G(alpha N) with the number of Pro residues (from 0 to 3) suggests that the formation of a contact between the S-atom in the C-terminal Met residue and the N-atom of a deprotonated N-terminal amino group of Glu is controlled in peptides with 0 to 3 Pro residues by the relative diffusion of the S center dot+ and unoxidized N-atom. The overall rate constants of cyclization to form the (S.*.N)-bonded radical cations were estimated to be 3.8 X 10(6) , 1.8 x 10(6) , and 8.1 x 10(5) s(-1) for peptides with n = 0, 1, and 2 Pro residues, respectively. If activation is the same for all of the peptides, then these rate constants are a direct indication for the end-to-end dynamics along the chain.

Asymmetric catalysis with readily available, cheap, and non-toxic alkaline earth metal catalysts represents a sustainable alternative to conventional synthesis methodologies. In this context, we describe the development of a first Mg-II-catalyzed enantioselective hydroboration providing the products with excellent yields and enantioselectivities. NMR spectroscopy studies and DFT calculations provide insights into the reaction mechanism and the origin of the enantioselectivity which can be explained by a metal-ligand cooperative catalysis pathway involving a non-innocent ligand.

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.

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.

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.
