A novel approach has been developed for the synthesis of a wide range of alpha-ketoacetals by the reaction of alkyl/aryl methyl ketones and aliphatic alcohols in the presence of selenium dioxide catalyzed by p-toluenesufonic acid. This method represents a general route to obtain a wide variety of alpha-ketoacetals in a simple, rapid, and practical manner. This approach is particularly attractive because of the easy availability of the starting materials, mild reaction temperature, and good yields of the products. The resulting alpha-ketoacetals are of much synthetic value as organic intermediates.

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.

A quantitative Lewis acidity/basicity scale toward boron-centered Lewis acids has been developed based on a set of 90 experimental equilibrium constants for the reactions of triarylboranes with various O-, N-, S-, and P-centered Lewis bases in dichloromethane at 20 degrees C. Analysis with the linear free energy relationship log K-B=LA(B)+LBB allows equilibrium constants, K-B, to be calculated for any type of borane/Lewis base combination through the sum of two descriptors, one for Lewis acidity (LA(B)) and one for Lewis basicity (LBB). The resulting Lewis acidity/basicity scale is independent of fixed reference acids/bases and valid for various types of trivalent boron-centered Lewis acids. It is demonstrated that the newly developed Lewis acidity/basicity scale is easily extendable through linear relationships with quantum-chemically calculated or common physical-organic descriptors and known thermodynamic data (Delta HBF3 ). Furthermore, this experimental platform can be utilized for the rational development of borane-catalyzed reactions.

The first highly efficient and practical chiral BrOnsted acid catalyzed dynamic kinetic asymmetric hydroamination (DyKAH) of racemic allenes and asymmetric hydroamination of unactivated dienes with both high E/Z selectivity and enantioselectivity are described herein. The transformation proceeds through a new catalytic asymmetric model involving a highly reactive pi-allylic carbocationic intermediate, generated from racemic allenes or dienes through a proton transfer mediated by an activating/directing thiourea group. This method affords expedient access to structurally diverse enantioenriched, potentially bioactive alkenyl-containing aza-heterocycles and bicyclic aza-heterocycles.

Herein, we propose novel quinolones incorporating an INH moiety as potential drug templates against TB. The quinolone-based compounds bearing an INH moiety attached via a hydrazide-hydrazone bond were synthesised and evaluated against Mycobacterium tuberculosis H37Rv (MTB). The compounds were also evaluated for cytotoxicity against HeLa cell lines. These compounds showed significant activity (MIC90) against MTB in the range of 0.2-8 mu M without any cytotoxic effects. Compounds 10 (MIC90; 0.9 mu M), 11 (MIC90; 0.2 mu M), 12 (MIC90; 0.8 mu M) and compound 15 (MIC90; 0.8 mu M), the most active compounds in this series, demonstrate activities on par with INH and superior to those reported for the fluoroquinolones. The SAR analysis suggests that the nature of substituents at positions -1 and -3 of the quinolone nucleus influences anti-MTB activity. Aqueous solubility evaluation and in vitro metabolic stability of compound 12 highlights favourable drug-like properties for this compound class.

For the dehydroxylation of aldoximes with 4-nitro-1-((trifluoromethyl)sulfonyl)-imidazole (NTSI), slight modifications of reaction conditions resulted in significantly different reaction paths to provide either nitriles or isonitriles. The challenging conversion of aldoximes into isonitriles was achieved under mild conditions.

SDS of cas: 100-19-6. I found the field of Biochemistry & Molecular Biology; Chemistry very interesting. Saw the article Syntheses and evaluation of new Quinoline derivatives for inhibition of hnRNP K in regulating oncogene c-myc transcription published in 2019, Reprint Addresses Li, D (corresponding author), Sun Yat Sen Univ, Sch Pharmaceut Sci, 132 Waihuan East Rd, Guangzhou 510006, Guangdong, Peoples R China..

Aberrant overexpression of heterogeneous nuclear ribonucleoprotein K (hnRNP K) is a key feature in oncogenesis and progression of many human cancers. hnRNP K has been found to be a transcriptional activator to up-regulate c-myc gene transcription, a critical proto-oncogene for regulation of cell growth and differentiation. Therefore, down-regulation of c-myc transcription by inhibiting hnRNP K through disrupting its binding to c-myc gene promoter is a potential approach for cancer therapy. In the present study, we synthesized and screened a series of Quinoline derivatives and evaluated their binding affinity for hnRNP K. Among these derivatives, (E)-1-(4-methoxyphenyl)-3-(4 morpholino-6-nitroquinolin-2-yl)prop-2-en-1-one (compound 25) was determined to be the first-reported hnRNP K binding ligand with its K-D values of 4.6 and 2.6 mu M measured with SPR and MST, respectively. Subsequent evaluation showed that the binding of compound 25 to hnRNP K could disrupt its unfolding of c-myc promoter i-motif, resulting in down-regulation of c-myc transcription. Compound 25 showed a selective anti-proliferative effect on human cancer cell lines with IC50, values ranged from 1.36 to 3.59 mu M. Compound 25 exhibited good tumor growth inhibition in a Hela xenograft tumor model, which might be related to its binding with hnRNP K. These findings illustrated that inhibition of DNA-binding protein hnRNP K by compound 25 could be a new and selective strategy of regulating oncogene transcription instead of targeting promoter DNA secondary structures such as G-quadruplexes or i-motifs.

A new photoactive Pt (II) hydroxyquinoline complex has been covalently linked into the structure of an iminebased layered covalent organic framework (COF) through the monomer truncation strategy. Such strategy allows the incorporation of molecular fragments with only one functional group able to condensate into the imine-framework. The photocatalytic activity of the resulting Pt@COF has been applied to the oxidation of sulfides to sulfoxides, obtaining excellent results for all the studied cases, and showing that this reaction goes through both photoredox and energy transfer processes. The results obtained showed a great enhancement of the catalytic activity (up to 25,000 turnover number, TON), stability and a significant decrease on the reaction times, as a consequence of immobilization and isolation of Pt(II) centers into the organic framework. In addition, Pt@COF has been proved to be an excellent heterogeneous photocatalyst also in exclusive photoredox processes, reaching 7500 TON in hydrodebromination reactions.

The first general palladium-catalyzed alpha-arylation of arylacetonitriles with aryl and heteroaryl sulfonates are reported. Pd(OAc)(2) associated with XPhos serves as the effective catalyst to facilitate this reaction. A broad range of electron-rich, -neutral, -deficient, and sterically hindered aryl/heteroaryl tosylates and mesylates are coupled with arylacetonitriles bearing different substituents to give the corresponding products in good to excellent yields. Catalyst loading down to 0.1 mol-% Pd was achieved, and 22 unprecedented compounds were synthesized from 43 demonstrated examples using this method. Its applicability with the modification of biological phenolic compounds was successfully demonstrated. The Pd/XPhos system catalyzed the alpha-arylation and followed by alkylation in one-pot sequential conditions, resulting in the direct synthesis of compounds containing quaternary center- and deuterium-containing compounds in good to excellent yields.
