Background: Much attention has been focused on heterogeneous catalysts. Reactions with these recoverable and reusable catalysts are clean, selective with high efficiency. Among the heterogeneous solid acid catalyst in organic synthesis, Carbon-Based Solid Acids (CBSAs), which are important solid acid with many practical and research applications have been extensively studied. In this work, green Pistachio peel, a biomass waste, was converted into a novel carbon-based solid acid catalyst (Pis-SO3H). Objective: The aim of this work is to synthesize highly sulfonated carbon as an efficient, recyclable, nontoxic solid acid catalyst by simultaneous sulfonation, dehydration and carbonization of green Pistachio peel as biomass and investigate the catalytic activity of Pis-SO3H in acetalization, thioacetalization, acylation of aldehydes and synthesis of 3,3′-Arylmethylene-bis(4-hydroxycoumarin) derivatives. Methods: Pis-SO3H was synthesized by an integrated fast one- step hydrothermal carbonization and sulfonation process in the presence of sulfuric acid. The characterization of the physicochemical properties of Pis-SO3H was achieved by XRD, FT-IR, FE-SEM, and elemental analysis. Results: The result of acid-base titration showed that the total acidity of the catalyst was 7.75 mmol H(+)g(-1). This new heterogeneous catalyst has been efficiently used for the chemoselective thioacetalization, acetalization and acylation of aldehyde and the synthesis of biscoumarins under solvent-free conditions. All the reactions work easily in high yields. The antimicrobial activity of some of the biscoumarins was evaluated in screening by disk diffusion assay for the zone of inhibition. Conclusion: The catalytic activity of the Pis-SO3H was investigated during acetalization, thioacetalization, acylation and synthesis of biscoumarins. The results of protection of carbonyl groups and synthesis of biscoumarins in the present work offer effective alternatives for environmentally friendly utilization of abundant biomass waste.

Synthesis and characterization of novel coumarins containing carborane units were described. The breakdown reactions of cyclic oxonium derivatives of cobalt bis (1,2-dicarbollide) and closo-dodecaborate anions with a series of 7-hydroxy-3-substituted coumarins led to conjugates attached via C-7 position of the coumarin unit. The corresponding reactions of cobalt bis (1,2-dicarbollide) anion with 3-(4-hydroxybenzoyl)-7-methoxy-2H-chromen-2-one led to conjugates attached via C-3 position. Novel conjugates were isolated in the form of alkali metal salts. Therefore, these conjugates are of interest for the fluorescent study in aqua media. (C) 2020 Elsevier B.V. All rights reserved.

Curcumin (CUR) is a symmetrical dicarbonyl compound with antibacterial activity. On the other hand, pharmacokinetic and chemical stability limitations hinder its therapeutic application. Monocarbonyl analogs of curcumin (MACs) have been shown to overcome these barriers. We synthesized and investigated the antibacterial activity of a series of unsymmetrical MACs derived from acetone against Mycobacterium tuberculosis and Gram-negative and Gram-positive species. Phenolic MACs 4, 6 and 8 showed a broad spectrum and potent activity, mainly against M. tuberculosis, Acinetobacter baumannii and methicillin-resistant Staphylococcus aureus (MRSA), with MIC (minimum inhibitory concentration) values ranging from 0.9 to 15.6 mu g/mL. The investigation regarding toxicity on human lung cells (MRC-5 and A549 lines) revealed MAC 4 was more selective than MACs 6 and 8, with SI (selectivity index) values ranging from 5.4 to 15.6. In addition, MAC 4 did not demonstrate genotoxic effects on A549 cells and it was more stable than CUR in phosphate buffer (pH 7.4) for 24 h at 37 degrees C. Fluorescence and phase contrast microscopies indicated that MAC 4 has the ability to disrupt the divisome of Bacillus subtilis without damaging its cytoplasmic membrane. However, biochemical investigations demonstrated that MAC 4 did not affect the GTPase activity of B. subtilis FtsZ, which is the main constituent of the bacterial divisome. These results corroborated that MAC 4 is a promising antitubercular and antibacterial agent.

Direct oxidative coupling of different inert C-H bonds is the most straightforward and environmentally benign method to construct C-C bonds. In this paper, we developed a Pd-catalyzed intramolecular oxidative coupling between unactivated aliphatic and aryl C-H bonds. This chemistry showed great potential to build up fused cyclic scaffolds from linear substrates through oxidative couplings. Privileged chromane and tetralin scaffolds were constructed from readily available linear starting materials in the absence of any organohalides and organometallic partners.

Herein we report the development of a photocatalytic strategy for the divergent preparation of functionalized bicyclo[1.1.1]pentylamines. This approach exploits, for the first time, the ability of nitrogen-radicals to undergo strain-release reaction with [1.1.1]propellane. This reactivity is facilitated by the electrophilic nature of these open-shell intermediates and the presence of strong polar effects in the transition-state for C-N bond formation/ring-opening. With the aid of a simple reductive quenching photoredox cycle, we have successfully harnessed this novel radical strain-release amination as part of a multicomponent cascade compatible with several external trapping agents. Overall, this radical strategy enables the rapid construction of novel amino-functionalized building blocks with potential application in medicinal chemistry programs as p-substituted aniline bioisosteres.

,-Unsaturated esters and lithium 1,3-dien-2-olates are known to furnish bicyclic lithium enolates by anionic Diels-Alder reactions. However, in principle, the respective products might form not only in a single step but also in two consecutive – or tandem – Michael additions, the first of which occurs intermolecularly, the second intramolecularly. Three cyclic lithium dienolates and four esters with a stereogenic C=C bond reacted to give Diels-Alder adducts (10 times) or failed to react (2 times). Seven of the reactive combinations furnished adducts wherein the configuration of the former ester moiety had in part inverted. This precludes concerted pathways as their origins. This was a surprise since donors at C-2 of the 1,3-diene accelerate normal electron-demand Diels-Alder reactions in the order alkyl < aryl < alkoxy approximate to trialkylsiloxy < acylamino. With (LiO?)-O-circle plus being a far better donor still, it is not obvious why the mechanism is non-concerted rather than concerted (and still more asynchronous). Formula: C5H8O2.

The synthesis, characterization, and electrochemical and photophysical properties of the phosphonate-derivatized carbazole (CBZ) and boron dipyrromethene (BODIPY) chromophores in the dyes, BODIPY(CBZ)(2)PO3H2 (8) and BODIPY(Tol)(2)PO3H2 (7), are described. The oxide-bound dyes have been explored as light absorbers in dyesensitized photoelectrosynthesis cell (DSPEC) applications. The BODIPY-CBZ phosphonate ester (6) features a broad, intense UV-visible absorption spectrum with absorptions at 297 and 650 nm that arise from mixed transitions at the CBZ and BODIPY units. Electrochemical measurements on BODIPY(CBZ)(2)Br (4) in 0.1 M [nBu(4)N] [PF6] in dichloromethane, vs normal hydrogen electrode (NHE), reveal reversible oxidations at 1.19 and 1.41 V and a reversible reduction at -0.59 V. On indium tin oxide (ITO) and TiO2, a reversible one-electron oxidation appears for 7 at 0.86 and 0.90 V vs NHE in dichloromethane, respectively, which demonstrates the redox stability on metal oxide surfaces. The results of nanosecond transient absorption measurements on SnO2/TiO2 electrodes provide direct evidence for excited-state electron injection into the conduction band of TiO2 following 590 nm excitation. A longer lifetime for 8(+) compared to 7(+) is consistent with extensive intramolecular charge separation between the CBZ and BODIPY units on the surface. Photoelectrochemical studies on 8 on a SnO2/TiO2 photoanode resulted in sustained photocurrents with current maxima of similar to 200 mu A/cm(2) with hydroquinone added as a reductant under 1 sun (AM1.5 100 mWcm(-2)) illumination at pH 4.5 in 0.1 M acetate buffer and 0.4 M LiClO4. On mixed SnO2/TiO2 electrode surfaces, with the added catalyst [Ru(Mebimpy)((4,4′-(OH)(2)PO-CH2)(2)bpy)(OH2)](2+) and chromophores 7 and 8, addition of 0.1 M benzyl alcohol resulted in sustained photocurrents of 12 and 35 mu A/cm(2), consistent with oxidation to benzaldehyde.

Herein a new Ru-phosphine complex (1) with molecular formula [RuL(PPh3)Cl-2] is reported where L is a redox active pincer ligand 2,6-bis(phenylazo)pyridine. The isolated complex has been characterized by usual spectroscopic techniques including single crystal X-ray crystallographic analysis. Complex 1 efficiently catalyzes aerobic oxidation of a wide range of primary and secondary benzylic, allylic, heterocyclic, alicyclic alcohols under mild conditions and is found to be superior over several other Ru (0, +2 and + 3), Ru-H and Ru-PPh3 catalysts. Mechanistic studies indicate that a transient Ru-H intermediate is formed in the catalytic cycle which gets switched into a Ru-hydrazo intermediate via hydrogen-walking mechanism. The catalyst is regenerated by aerial oxidation producing H2O2 as a by-product.

HPLC of Formula: C5H8O2. I found the field of Physics very interesting. Saw the article Strong enhancement of coherent terahertz radiation by target ablation using picosecond laser pulses published in 2020, Reprint Addresses Lin, C (corresponding author), Peking Univ, State Key Lab Nucl Phys & Technol, Beijing 100871, Peoples R China.; Lin, C (corresponding author), Peking Univ, Key Lab HEDP, Minist Educ, CAPT, Beijing 100871, Peoples R China.; Lin, C (corresponding author), Beijing Laser Accelerat Innovat Ctr, Beijing 101400, Peoples R China..

We have studied the generation of terahertz (THz) radiation via the interaction of an intense femtosecond laser pulse with aluminum (Al) and plastic targets pre-ablated by a picosecond ablation pulse. The measurements of the plasma shadowgraph and 1D-MULTI simulations show a similar micrometer density scale length of the pre-ablated plasma for the two types of targets after ablation. It is found that for the Al target, the intensity of THz radiation increased obviously under the condition of ablation, and only with the appropriate ablation delay time, the cutoff energy and charge of the accelerated protons also increased. 2D-simulations using the EPOCH program indicate that the strong enhancement of THz for the Al target is due to the increased number of energetic electrons from the interaction between the main laser and the ablated plasma. However, for the plastic targets, the intensity of THz radiation was almost vanished in the case of ablation, but the accelerated protons still existed and the cutoff energy even tended to increase. However, due to the lack of ability to simulate the molecular structure, we cannot distinguish between Al and plastic targets in the simulation. The mechanism of radiation suppression by ablation of the plastic target needs further investigation.

The synthesis of chiral C-2-symmetric bis(bipyridine N,N’-dioxide) and bis(bipyridine N-monooxide) derivatives featuring bipyridine-annulated bicyclo[3.3.1 ]nonane framework is reported. The new Lewis basic bipyridine N,N’-dioxides exhibited good catalytic activity in the asymmetric allylation of aldehydes with allyltrichlorosilane, furnishing corresponding homoallylic alcohols in up to 75% ee. Reduction of ketimines and beta-enamino esters with trichlorosilane catalyzed by bipyridine N,N’-dioxides proceeded in high yields but modest enantioselectivity (38-54% ee); good levels of asymmetric induction (up to 73% ee) were attained in the reduction of alpha-imino esters at room temperature.
