Herein, the universal design of high-efficiency stimuli-responsive luminous materials endowed with mechanochromic luminescence (MCL) and thermally activated delayed fluorescence (TADF) functions is reported. The origin of the unique stimuli-triggered TADF switching for a series of carbazole-isophthalonitrile-based donor-acceptor (D-A) luminogens is demonstrated based on systematic photophysical and X-ray analysis, coupled with theoretical calculations. It was revealed that a tiny alteration of the intramolecular D-A twisting in the excited-state structures governed by the solid morphologies is responsible for this dynamic TADF switching behavior. This concept is applicable to the fabrication of bicolor emissive organic light-emitting diodes using a single TADF emitter.

An oxidative esterification of aldehydes with alkanols catalyzed by an in situ generated low-valent cobalt system has been developed using an enone as a mild oxidant. Mechanistic studies revealed that it proceeds through a Co(i)-catalyzed hydrogen-transfer route, wherein the -vinyl moiety in the bidentate enone functions as a hydride acceptor. Meanwhile, Co(i)-catalyzed formyl C-H activation occurred as a competing reaction leading to aldehyde dimerization. The occurrence of the usually kinetically disfavored hydride transfer step therein was significantly increased in the presence of an enone reacting as a hydride transfer initiator.

A highly enantioselective three-component hydroacyloxylation/1,4-conjugate addition ofortho-hydroxybenzyl alcohols, ynamides and carboxylic acids was developed under mild reaction conditions in the presence of a chiralN,N ‘-dioxide/Sc(OTf)(3)complex, which went throughin situgeneratedortho-quinone methides with alpha-acyloxyenamides, delivering a range of corresponding chiral alpha-acyloxyenamides derivatives containinggem(1,1)-diaryl skeletons in moderate to good yields with excellenteevalues. The scale-up experiment and further derivation showed the practicality of this catalytic system. In addition, a possible catalytic cycle and transition state model was proposed to elucidate the origin of the stereoselectivity based on X-ray crystal structure of the alpha-acyloxyenamide intermediate and product.

Background and Purpose Previous studies have shown that Creosote bush-derived nordihydroguaiaretic acid (NDGA) exerts beneficial actions on the key components of metabolic syndrome including dyslipidaemia, insulin resistance and hypertension in several relevant rodent models. Here, we synthesized and screened a total of 6 anti-hyperlipidaemic analogues of NDGA and tested their efficacy against hepatic lipid metabolism in a high-fructose diet (HFrD) fed dyslipidaemic rat model. Experimental Approach HFrD fed Sprague-Dawley rats treated with NDGA or one of the six analogues were used. Serum samples were analysed for blood metabolites, whereas liver samples were quantified for changes in various mRNA levels by real-time RT-PCR. Key Results Oral gavage of HFrD-fed rats for 4 days with NDGA analogues 1 and 2 (100 mg center dot kg(-1)center dot day(-1)) suppressed the hepatic triglyceride content, whereas the NDGA analogues 2, 3 and 4, like NDGA, decreased the plasma triglyceride levels by 70-75%. qRT-PCR measurements demonstrated that among NDGA analogues 1, 2, 4 and 5, analogue 4 was the most effective at inhibiting the mRNA levels of some key enzymes and transcription factors involved in lipogenesis. All four analogues almost equally inhibited the key genes involved in triglyceride synthesis and fatty acid elongation. Unlike NDGA, none of the analogues affected the genes of hepatic fatty acid oxidation or transport. Conclusions and Implications Our data suggest that NDGA analogues 1, 2, 4 and 5, particularly analogue 4, exert their anti-hyperlipidaemic actions by negatively targeting genes of key enzymes and transcription factors involved in lipogenesis, triglyceride synthesis and fatty acid elongation. These analogues have therapeutic potential.

A convenient and efficient method has emerged for the one-pot synthesis of substituted quinazolin-4(3 H) -ones and nonaromatic alkaloids. 2-Substituted quinazolin-4(3H)-ones, 2,3-disubstituted quinazolin-4(3 H) -ones, and 2,3-dihydroquinazolin-4(1 H) -ones were obtained at yields of 46% to 95% by a one-pot reaction of N -(2-aminobenzoyl) benzotriazoles with amines and orthoesters or aldehydes under catalyst-free conditions.

Magnetite nanoparticles (MNPs) have been evaluated for inhibiting microbial growth and biofilm formation. In this study the effect of the nanocomposite Moroccan propolis extract / MNPs acting against methicillin resistant strains of Staphylococcus aureus (MRSA) was evaluated. Chemical composition of propolis was established by pyrolysis coupled to gas chromatography and mass spectrometry method (pyrolysis GC/MS). MNPs were obtained through the co-precipitation method. The fabricated nanostructure was characterized by X-ray Diffraction (DRX), Transmission Electron Microscopy (TEM), and Fourier Transform-Infrared Spectroscopy (FTIR). TEM of MNPs provided a particle average size of 15 nm, FTIR spectral analysis enabled a fast way of identification of MNPs, attesting the occurrence of the different combinations. The use of MNPs loaded with propolis and the antibiotic chloramphenicol at Minimum Inhibitory Concentration (MIC) value inhibited the bacterial growth of MSSA (methicillin susceptible strain of S. aureus) and MRSA strains. After the treatment with MNPs-OA-P-CLo nanocomposite (MNPs with oleic acid, propolis and chloramphenicol), the disruption of the bacterial cell was observed by TEM. The combination of propolis and chloramphenicol in free form at MIC value largely impaired both MSSA and MRSA strains as, after 2 h of treatment, no viable cells of MRSA 2 and MRSA 16 were recovered. Hence, the results elucidated a new antibacterial nanocomposite synthesis, for possible applications as prospective nanoantibacterial agents or drug carriers.

In this article, a direct synthetic method for alkyl 5-arylthiophene-2-thiocarboxylates was reported. Treatment of alkyl 2-aroyl-1-chlorocyclopropanecarboxylates with excess amount of Lawesson’s reagent readily afforded alkyl 5-arylthiophene-2-thiocarboxylates in good to excellent yields under mild conditions. This cycloisomerization reaction process would be initiated by a ring-opening of the strained cyclopropane.

We report the highly enantioselective synthesis of P-chiral tertiary phosphine oxides featuring an ethynyl group via Cu(i)-catalyzed azide-alkyne cycloaddition. Newly developed chiral pyridinebisoxazolines (PYBOX) bearing a bulky C4 shielding group play an important role in achieving excellent enantioselectivity while suppressing side bis-triazoles formation in desymmetrizing prochiral diethynylphosphine oxides. Notably, by tuning the size of the C4 shielding group, it is possible to achieve excellent remote enantiofacial control in desymmetrizing phosphole oxide-diynes with the prochiral P-center farther from the ethynyl group by four covalent bonds. Time-dependent enantioselectivity is observed for these desymmetric CuAAC reactions, suggesting a synergic combination of a desymmetrization and a kinetic resolution, and our ligands prove to be better than unmodified PYBOX in both steps. This finding contributes to a highly enantioselective kinetic resolution of racemic ethynylphosphine oxides. The resulting chiral ethynylphosphine oxides are versatile P-chiral synthons, which can undergo a number of diversifying reactions to enrich structural diversity.

The synthesis of alpha-alkenyl alpha,beta-unsaturated ketones using germanium(II) salts is reported. Oxagermacycles derived from alpha,beta-unsaturated ketones with germanium(II) salts and aldehydes can be transformed into a-alkenyl a 6-unsaturated ketones. Ammonium salts promoted the elimination of Ge(II) species to afford the two classes of alpha-alkenyl alpha,beta-unsaturated ketones in good yields. The alpha-alkenyl alpha,beta-unsaturated ketones are precursors for multisubstituted heterocycles.
