The heterogeneous heteropolyacid-catalyzed acetalization of glycerol with acetone was investigated under solvent-free conditions. In this work, the calcined Ta/W mixed addenda heteropolyacid catalyst ({H-20}-355) was employed as a solid acid catalyst and showed much higher activity than these soluble Keggin-type catalysts in the acetalization of glycerol with acetone due to its superacidity (H-0 =-12.95). Meanwhile, it showed high stability in catalytic recycles and extended for acetalization of glycerol with the other aldehydes and ketones. Based on the catalyst characterization by X-ray diffraction (XRD), scanning electron microscopy (SEM), P-31 NMR spectra, FT-IR spectra, pyridine-absorbed FT-IR, and Hammett acidity functions (H-0) by UV-vis spectroscopy, it was found that the acidic strength of the Ta/W mixed addenda heteropolyacid was highly dependent on the contents of crystalline water that could be tuned by calcination temperature. Notably, the solid superacid catalyst {H-20}355 was swollen by acetone, exhibiting an interesting pseudo-liquid behavior, which served as a microreactor and facilitated the reaction. Furthermore, after the acetalization reaction of glycerol with furfural (98% yield of acetal) on {H-20}-355 catalyst, the furan ring of the acetal products can be hydrogenated sequentially into dioxolane or dioxane with Pd/C catalyst under room temperature condition without the need of any isolation procedure.

The [4+2] cycloaddition reaction of the (dimesitylphosphino) cyclopentadienes 5a,b with N-phenyl-maleimide gave the norbornene derivative 9. Its reduction with LiAlH4 produced the N-phenyl-pyrrolidino-annulated system 10. Treatment with Piers’ borane gave the respective P/B FLP 12 as the major product, which cleaved dihydrogen under mild conditions to yield the phosphonium/hydrido borate product 14. Reaction of the phosphino-norbornene 10 with 2 M equiv. of Piers’ borane [HB(C6F5)(2)] followed by exposure to dihydrogen eventually gave the HB(C6F5)(2) adduct 15. This served as a catalyst for the hydrogenation of a series of chalcone derivatives. The system requires a pre-activation period before becoming active for the conjugated enone hydrogenation.

COA of Formula: C15H12O. I found the field of Chemistry very interesting. Saw the article Potassium Poly(Heptazine Imide): Transition Metal-Free Solid-State Triplet Sensitizer in Cascade Energy Transfer and [3+2]-cycloadditions published in 2020.0, Reprint Addresses Savateev, A; Antonietti, M (corresponding author), Max Planck Inst Colloids & Interfaces, Dept Colloid Chem, Muhlenberg 1, D-14476 Potsdam, Germany..

Polymeric carbon nitride materials have been used in numerous light-to-energy conversion applications ranging from photocatalysis to optoelectronics. For a new application and modelling, we first refined the crystal structure of potassium poly(heptazine imide) (K-PHI)-a benchmark carbon nitride material in photocatalysis-by means of X-ray powder diffraction and transmission electron microscopy. Using the crystal structure of K-PHI, periodic DFT calculations were performed to calculate the density-of-states (DOS) and localize intra band states (IBS). IBS were found to be responsible for the enhanced K-PHI absorption in the near IR region, to serve as electron traps, and to be useful in energy transfer reactions. Once excited with visible light, carbon nitrides, in addition to the direct recombination, can also undergo singlet-triplet intersystem crossing. We utilized the K-PHI centered triplet excited states to trigger a cascade of energy transfer reactions and, in turn, to sensitize, for example, singlet oxygen (O-1(2)) as a starting point to synthesis up to 25 different N-rich heterocycles.

The most red-shifted hemithioindigo photoswitches have been identified through systematic introduction of aryl units to a parent pyrrole hemithioindigo photoswitch. Increasing the size of the 5′-aryl substituent is ineffective at producing further redshifted chromophores. A second generation of 3′,5′-diarylated photoswitches which possess increased tunability is reported. Experimental and computational evidence indicates the 4′ position is electronically isolated from the bulk of the conjugated system. (C) 2019 Elsevier Ltd. All rights reserved.

Inspired by the synergistic effects of hetero-aromatic scaffolds on curcumin, a novel array of pyrazoline substituted curcumin analogs was designed. Multi-scale computational studies were carried out to target the proposed analogs on human kinase beta (IKK-beta), a potential anti-cancer target. In molecular docking analysis, all the eleven molecules were observed to bind the target site and 4-bromo-4′-chloro analog displayed three hydrogen bond interactions with a docking score of -11.534 kcal/mol higher than parent molecule, curcumin (docking score = -7.12 kcal/mol) as the propellant shaped of analogs aided in proper binding with Kinase Domain binding pocket. The molecular dynamics and simulations studies revealed that the stable complexes of lead molecule were developed as the minimal deviations per residue of protein found within the range of 0.11 to 0.92 angstrom. The proposed compounds were synthesized, characterized and biologically evaluated against human cervical cancer cell line, HeLa, using standard MTT cell assay. Bio-evaluation studies exhibited superior cytotoxic profile for many analogs as Chloro bromo analog with IC50 value (8.7 mu g/mL) exhibited fivefolds improvement in the potency in comparison to curcumin (IC50 = 42.4 mu g/mL) but was less potent than the standard drug, paclitaxel (IC50 = 0.008 mu g/mL). The apoptotic effect was evaluated in the terms of caspase-3 enzyme cleavage and exhibited 70.5% of apoptosis significantly (p < 0.05) higher than 19.9% induced by curcumin. In short, 4-bromo-4'-chloro analog was the potent cytotoxic agent in this structural class and must be evaluated further under a set of stringent parameters for transforming in to a clinically viable therapeutic molecule.

A new methodology for the synthesis of alpha-diketones was reported via a one-pot cascade process from aldehydes and ketones catalyzed by a bifunctional iron nanocomposite using H2O2 as a green oxidant in water. The one-pot strategy showed excellent catalytic stability, comprehensive suitability of substrates and important practical utility for directly synthesizing biologically active and medicinally valuable N-heterocycles via an intermittent process.

In an attempt to synthesise new tyrosinase inhibitors, we designed and synthesised a series of chalcone-hydroxypyridinone hybrids as potential tyrosinase inhibitors adopting strategic modifications of kojic acid. All the newly synthesised compounds were characterised by NMR and mass spectrometry. Initial screening of the target compounds demonstrated that compounds1a,1d, and1nhad relatively strong inhibitory activities against tyrosinase monophenolase, with IC(50)values of 3.07 +/- 0.85, 2.25 +/- 0.8 and 2.75 +/- 1.19 mu M, respectively. The inhibitory activity against monophenolase was 6- to 8-fold higher than that of kojic acid. Compounds1a,1d, and1nalso showed inhibition of diphenolase, with IC(50)values of 17.05 +/- 0.07, 11.70 +/- 0.03 and 19.3 +/- 0.28 mu M, respectively. The inhibition kinetics of diphenolase indicates that compounds1aand1dinduce reversible inhibition on tyrosinase. Finally, we found that copper coordination should be one of the important inhibitory mechanism of these compounds in tyrosinase.

Efficient hydrogenation of electron-deficient internal olefins and alkynes access to saturate ketone with CH3OH as a single hydrogen donor under electrochemical conditions has been successfully developed. This hydrogenation strategy can be used to convert electron-deficient internal olefins and alkynes to saturate ketone under electrochemical conditions with exogenous-reductant and a metal catalyst. Mechanistic studies reveal that radical hydrogenation was involved in this transformation. Notably, various electron-deficient internal olefins and alkynes could be tolerated in such an electrochemical hydrogenation synthetic strategy and can be easily scaled up with good efficiency.
