Herein, we describe the formation of quaternary carbon centers with excellent diastereoselectivity via a strain-release protocol. An organometallic species is generated by Cp*Rh(III)-catalyzed C-H activation, which is then coupled with strained bicyclobutanes (BCBs) and a prochiral carbon electrophile in a three-component reaction. This work illustrates a rare example of BCBs in transition metal catalysis and demonstrates their broad potential to access novel reaction pathways. The method developed exhibits ample functional group tolerance, and the products can be further transformed into valuable alpha-quaternary beta-lactones. Preliminary mechanistic investigations suggest a twofold C-C bond cleavage sequence involving sigma-bond insertion and an ensuing beta-carbon elimination event.

Self-assembled nanotechnology has been used widely in various well-defined microstructures fabrication. Herein, this synthetic protocol was successfully utilized to in situ or hierarchically prepare magnetic Pt nanocomposites Fe3O4@Pt via a distinguishing two-step process. The distinction of these two pathways is due to the different synthetic processes. In the case of in situ preparation (Path I), it involves a supramolecular self-assembly of boron clusters with gamma-CD on Fe3O4 substrate and then followed by in situ formation of Pt nanoparticles (NPs). But in the case of hierarchical preparation (Path II), the first step is preparing Pt NPs colloids reduced by boron clusters Cs-2[closo-B12H12], and subsequent step is immobilizing the as-prepared [closo-B12H12](2-)-capped Pt NPs on the Fe3O4@gamma-CD. The success of these two fabrication strategies lies in the use of trifunctional boron clusters (reductant, stabilizer, and superchaotropic anchor). Both of the as-prepared Fe3O4@Pt nanocomposites showed good catalytic performance in the selective nitro-group reduction of nitroaromatics. A control test further indicated that the in situ prepared Fe3O4@Pt nanocomposites, with smaller size and higher loading of Pt NPs, exhibited a better catalytic performance and recyclability.

A novel nonanuclear copper(II) complex obtained by a facile one-pot self-assembly was found to catalyze the hydroboration of ketones and aldehydes with the absence of an activator under mild, solvent-free conditions. The catalyst is air-and moisture-stable, displaying high efficiency (1980 h(-1) turnover frequency, TOF) and chemo-selectivity on aldehydes over ketones and ketones over imines. This represents a rare example of divalent copper catalyst for the hydroboration of carbonyls.

Aim and Objective: Nowadays, the design, synthesis and application of magnetically nanocomposite systems have attracted the attention of numerous scientists. The huge surface area and magnetic characteristic of nanoparticles as well as the inherent potentiality of the used metal species, makes them susceptible to have different reactivity in chemical reactions. In this context, we therefore encouraged to prepare a new design of magnetic nanocatalysts as CuFe2O4@SiO2@AAPTMS@Ni(II) and CuFe2O4@SiO2@AAPTMS@Cu(II) followed by monitoring of their catalytic activities towards reduction of nitroarenes with NaBH4. Materials and Methods: Magnetically nanoparticles of CuFe2O4@SiO2@AAPTMS@Ni(II) and CuFe2O4@SiO2@AAPTMS@Cu(II) were prepared through a four-step procedure: i) preparation of CuFe2O4 MNPs, ii) coating of CuFe2O4 nucleus by silica-layer using tetraethyl orthosilicate (TEOS), iii) layering of CuFe2O4@SiO2 MNPs with [3-(2-aminoethylamino)propyl] trimethoxysilane (AAPTMS), and iv) the complexation of CuFe2O4@SiO2@AAPTMS MNPs with an aqueous solution of Ni(OAc)(2)center dot 4H(2)O or Cu(OAc)(2)center dot H2O. Results: The catalytic activity of CuFe2O4@SiO2@AAPTMS@AAPTMS@Ni(II) and the Cu(II)-analogue towards reduction of nitroarenes with NaBH4 was studied. The examinations resulted that using a molar ratio of 1:2 for ArNO2 and NaBH4 in the presence of 20 mg of nanocomposites in H2O under reflux conditions reduces various aromatic nitro compounds to arylamines in high yields. Conclusion: The immobilization of Ni(II) and Cu(II) species on silica-layered CuFe2O4 was investigated. Magnetically nanoparticles of CuFe2O4@SiO2@AAPTMS@Ni(II) and the Cu(II)-analogue showed the perfect catalytic activity towards reduction of nitroarenes with NaBH4, in H2O. All reactions were carried out within 2-15 min to afford aniline products in high yields.

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.

Graphitic carbon nitride (g-C3N4, CN for short) is a compelling visible-light responsive photocatalyst. However, its photocatalytic efficiency is low due to the random carrier transfer in planes and insufficient redox potential. Herein, we build oxygen functional group modified sodium-doped carbon nitride (OH/Na co-functionalized carbon nitride) to promote directional transfer of charge carriers for acceleration of separation and enhance redox potential for efficient oxidation of NO in air. Specifically, the function of sodium atoms could control the directional transfer of random carriers from the intralayer to the oxygen functional group-modified surface for the purpose of effectively reducing photogenerated electron-hole recombination. Meanwhile, the modification by oxygen-containing functional groups could adjust the band structure of CN, thereby increasing the oxidation-reduction potential of NO in the photocatalyst. The transformation pathways and reaction mechanism of photocatalytic NO oxidation on CN and OH/Na co-functionalized carbon nitride have also been explicated by ESR spectroscopy and in situ DRIFTS and compared. This work provides a new method for simultaneously controlling the random transfer of carriers and adjusting the energy band structure of CN to optimize its photocatalytic efficiency. It is also possible to extend this strategy to improve the performance of other 2D layered catalysts for photocatalytic oxidation.

In view of expanding the structure activity relationship of xanthine oxidase inhibitors, a series of 3-oxo-6-aryl-2,3-dihydropyridazine-4-carbohydrazide/carboxylic acid derivatives were designed by molecular docking and synthesized. All the target compounds were evaluated for their in vitro XO inhibition by using febuxostat and allopurinol as the standard controls. Most of the hydrazide derivatives exhibited potency levels in the micromolar range. From the view of docking study, hydrazide derivatives bind to the active site of XO through a novel interaction mode, which is different from that of febuxostat bearing a carboxyl group. The most promising compound 8b was further subjected to kinetic analysis to deduce their modes of inhibition.

We report on the first cobalt corrole that effectively mediates the homogeneous hydrogenation of structurally diverse nitroarenes to afford the corresponding amines. The given catalyst is easily assembled prior to use from 4-tert-butylbenzaldehyde and pyrrole followed by metalation of the resulting corrole macrocycle with cobalt(II) acetate. The thus-prepared complex is self-contained in that the hydrogenation protocol is free from the requirement for adding any auxiliary reagent to elicit the catalytic activity of the applied metal complex. Moreover, a containment system is not required for the assembly of the hydrogenation reaction set-up as both the autoclave and the reaction vessels are readily charged under a regular laboratory atmosphere.
