Saw the article NaOH-Promoted Chemoselective Cascade Cyclization of Cyclopropyl Esters with Unsaturated lmines: Access to Bioactive Cyclopenta[c]pyridine Derivatives published in 2019.0, Reprint Addresses Jin, ZC (corresponding author), Guizhou Univ, Lab Breeding Base Green Pesticide & Agr Bioengn, Key Lab Green Pesticide & Agr Bioengn, Guiyang 550025, Guizhou, Peoples R China.. The CAS is 94-41-7. Through research, I have a further understanding and discovery of Chalcone.

A chemoselective cascade cycloaddition reaction is developed for green and efficient access to cyclopenta-[c]pyridine derivatives. Simple and inexpensive NaOH is used as the sole catalyst for this process. The delta-carbon of cyclopropyl ester is activated as a nucleophiic carbon to initiate highly chemoselective cascade reactions. Cyclopenta-[c]pyridines bearing various substituents are afforded in excellent yields. Preliminary studies on the bioactivities of the afforded products show promising antibacterial activities for potential applications in plant protections.

An olefinic difunctionalization method of enones was presented hereviaaerobic visible-light catalysis. A novel reactivity was showcased in conjunction with the selective Csp(2)-C(CO) bond activation of enones, which provided a convenient method for the preparation of various beta-thiolated-alpha-functionalized compounds. Moreover, the preliminary investigation of the mechanism indicated that a beta-peroxysulfide intermediate was formed under the promotion of visible light under an oxygen atmosphere, which finally induced the unexpected C-C bond cleavage.

Synthesis of fifteen C-4-aroyl-C-5-aryl-N-1-(5 ‘-deoxythymidin-5 ‘-yl)-1,2,3-triazoles have been reported starting from azidation of 5 ‘-p-toluenesulfonyloxythymidine followed by azide-alkene oxidative cycloaddition reaction of the resulted 5 ‘-azido-5 ‘-deoxythymidine with 1,3-diarylpropenones in dimethylformamide (DMF) in the presence of tetra-n-butylammonium hydrogen sulfate (n-Bu4N+HSO4-, TBAHS) as catalyst in 60 to 79% overall yields. Further, they were also synthesized by one pot sequential reaction of tosylated thymidine with sodium azide in DMF and then with 1,3-diarylpropenones in presence of n-Bu(4)N(+)HSO(4)(-)in superior yield of 70 to 95% than 60 to 79% in two step procedure. All fifteen synthesized compounds were screened for theirin vitroantiMycobacterium tuberculosisactivity against sensitive reference strain H37Rv and multi drug resistant (MDR) clinical isolate 591, and found to exhibit minimum inhibitory concentration (MIC) ranging from 2 to 15 mu g/mL, which was equivalent to the MIC of first line anti-tubercular drug streptomycin. All compounds qualify for their drug likeness when their physicochemical parameters were assessed using online MolSoft and Lipinski filter software, except their molecular weight. The cytotoxicity of potent compounds evaluated human monocytic cell line THP-1 by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay was found to be less as compared to the first line drug, isoniazid.

In search for new molecular entities as anti-TB agents, the benzimidazoquinazoline polyheterocyclic scaffold has been designed adopting the scaffold hopping strategy. Thirty-two compounds have been synthesized through an improved tandem decarboxylative nucleophilic addition cyclocondensation reaction of o-phenylenediamine with isatoic anhydride followed by further cyclocondensation of the intermediately formed 2-(o-aminoaryl) benzimidazole with trialkyl orthoformate/acetate. The resultant benzimidazoquinazolines were evaluated in vitro for anti-TB activity against M. tuberculosis H37Rv (ATCC27294 strain). Fourteen compounds exhibiting MIC values in the range of 0.4-6.25 mu g/mL were subjected to cell viability test against RAW 264.7 cell lines and were found to be non-toxic (< 30% inhibition at 50 mu g/mL). The active compounds were further evaluated against INH resistant Mtb strains. The most active compound 6x [MIC (H37Rv) of 0.4 mu g/mL] and the compound 6d [MIC (H37Rv) of 0.78 mu g/mL] were also found to be active against INH resistant Mtb strain with MIC values of 12.5 and 0.78 mu g/mL, respectively.

A complementing Pd- and Rh-catalyzed dynamic kinetic resolution (DKR) of racemic allenes leading to N-allylated pyrazoles is described. Such compounds are of enormous interest in medicinal chemistry as certified drugs and potential drug candidates. The new methods feature high chemo-, regio- and enantioselectivities aside from displaying a broad substrate scope and functional group compatibility. A mechanistic rational accounting for allene racemization and trans-alkene selectivity is discussed.

Aziridines are ubiquitous in bioactive molecules and often serve as key synthetic building blocks. We report herein an intramolecular KI/TBHP mediated oxidative dehydrogenative C(sp(3))-H amination reaction to synthesize a diverse array of trans-2,3-disubstituted aziridines in good yields under mild conditions. The synthetic utility of this protocol was further highlighted by a one-pot, two-step synthesis of unprotected aziridines.

To improve the properties of mesoporous carbon (MC), used as a catalyst support within electrodes, MC fibers (MCFs) were successfully synthesized by combining organic-organic self-assembly and electrospinning deposition and optimizing heat treatment conditions. The pore structure was controlled by varying the experimental conditions. Among MCFs, MCF-A, which was made in the most acidic condition, resulted in the largest pore diameter (4-5 nm), and the porous structure and carbonization degree were further optimized by adjusting heat treatment conditions. Then, since the fiber structure is expected to have an advantage when MCFs are applied to devices, MCF-A layers were prepared by spray printing. For the resistance to compression, MCF-A layers showed higher resistance (5.5% change in thickness) than the bulk MC layer (12.8% change in thickness). The through-plane resistance was lower when the fiber structure remained more within the thin layer, for example, +8 m omega for 450 rpm milled MCF-A and +12 m omega for 800 rpm milled MCF-A against the gas diffusion layer (GDL) 25BC carbon paper without a carbon layer coating. The additional advantages of MCF-A compared with bulk MC demonstrate that MCF-A has the potential to be used as a catalyst support within electrodes in energy devices.

Two new flavonoid glycosides, 2 ‘,4 ‘-dihydroxydihydrochalcone-4-O-beta-d-glucopyranoside (1) and medicarpin-3-O-beta-d-apiofuranosyl (1 -> 2)-beta-d-glucopyranoside (2), together with 34 known flavonoids were isolated from the 75% EtOH extract of the dried roots of Glycyrrhiza uralensis Fisch. Their structures were elucidated on the basis of spectroscopic analyses. The flavonoids were classified into ten sub-types, namely, dihydrochalcone (1), pterocarpans (2-4), flavones (5-6), flavanones (7-11), chalcones (12-15), retro-chalcones (16-18), isoflavans (19-21), isoflavones (22-28), 3-arylcoumarins (29-30), and coumestans (31-36). The isolated flavonoids were evaluated for in vitro hepatoprotective activity against d-galactosamine-induced toxicity in human hepatoma HepG2 cells.
