Benzimidazolone constitutes the core structure of numerous pharmaceuticals, agrochemicals, inhibitors, pigments, herbicides, and fine chemicals. Amination of hydrocarbons is an attractive tool for the creation of nitrogen-containing products. However, the multiple steps, harsh conditions, and low atom efficiencies often present in these reactions remain challenging. We present a multicomponent synthesis of functional benzimidazolones from arylamines, dialkylamines, and alcohols, acting via the sequence of copper-catalyzed oxidative tandem C-H aminations and alkyl deconstructive carbofunctionalization. The catalytic transformation forms multiple bonds in one single operation, uses readily available feedstocks and a naturally abundant Cu/O-2 catalyst system, has broad substrate scope, avoids pre-installation of aminating agents and directing groups, and provides high chemo- and regioselectivity, resulting in direct functionalization of inert C-H and C-C bonds via single-electron oxidation-induced activation mode. This platform can be expected to provide structurally diverse products with interesting biological, chemical, and physical properties.

This study evaluated the effect of different sugar smoking times on the flavour profiles of chicken drumsticks using an electronic nose (E-nose), electronic tongue (E-tongue), and headspace solid-phase microextraction gas chromatography-mass spectrometry (HS-SPME/GC-MS). The moisture content, water activity, pH, and L*-value decreased from 71.26% to 65.23%, 0.987 to 0.979, 6.66 to 5.36, and 61.84 to 52.34, respectively (P < 0.05). The a*-value and b*-value increased from 4.96 to 9.65 and 16.61 to 26.45, respectively (P < 0.05) with the increase in smoking times. Seventy-five volatile compounds were identified, and 18 volatile compounds were identified as key odour compounds and among them seven key volatile compounds with variable importance in projection (VIP) > 1 were detected. Principal component analysis of E-nose, E-tongue, and HS-SPME/GC-MS indicated that 3-, 4-, and 5-min smoking samples had similar odour and taste profiles. Sensory analysis indicated that the 4-min sample had increased overall acceptability. The correlation analysis of E-nose and key volatile compounds with odour activity value > 1 and VIP >1 confirmed that W1C, W3C, and W5C sensors were sensitive to aromatic compounds, and W2S sensor was sensitive to ketones. These results may provide guidance for smoked chicken producers to reasonably control flavour formation.

Background Pyrazoles have attracted particular attention due to the diverse biological activities associated with this heterocyclic system, and some have been shown to be cytotoxic to several human cell lines. Several drugs currently on the market have this heterocycle as the key structural motif, and some have been approved for the treatment of different types of cancer. Results 4,4MODIFIER LETTER PRIME-(Arylmethylene)bis(1H-pyrazol-5-ols) derivatives 3a-q were synthetized by a three components reaction of 3-methyl-1-phenyl-5-pyrazolone (1) with various benzaldehydes 2 catalyzed by sodium acetate at room temperature. The structures of all synthesized compounds were characterized by physicochemical properties and spectral means (IR and NMR) and were evaluated for their radical scavenging activity by DPPH assay and tested in vitro on colorectal RKO carcinoma cells in order to determine their cytotoxic properties. All 4,4MODIFIER LETTER PRIME-(arylmethylene)bis(1H-pyrazol-5-ols) derivatives 3a-q were synthetized in high to excellent yield, and pure products were isolated by simple filtration. All compounds have good radical scavenging activity, and half of them are more active than ascorbic acid used as standard. Conclusion Several derivatives proved to be cytotoxic in the RKO cell line. In particular, compound 3i proved to be a very potent scavenger with an IC50 of 6.2 +/- 0.6 mu M and exhibited an IC50 of 9.9 +/- 1.1 mu M against RKO cell. Autophagy proteins were activated as a survival mechanism, whereas the predominant pathway of death was p53-mediated apoptosis.

Oligonucleotides incorporating a central C-nucleoside with either a rigid or flexible benzaldoxime base moiety have been synthesized, and the hybridization properties of their metallacyclic derivatives have been studied by UV melting experiments. In all cases, the metallated duplexes were less stable than their unmetallated counterparts, and the metallacyclic nucleobases did not show a clear preference for any of the canonical nucleobases as a base-pairing partner. With palladated oligonucleotides, increased flexibility translated to less severe destabilization, whereas the opposite was true for the mercurated oligonucleotides; this reflects the greater difficulties in accommodating a rigid Pd-II-mediated base pair than a rigid Hg-II-mediated base pair within the base stack of a double helix.

In the present work, a temperature and pH-responsive hybrid catalytic system using copolymer-capped mesoporous silica particles with metal nanoparticles is proposed. The poly(2-(dimethylamino)ethyl methacrylate)(DMAEMA)-co-N-tert-butyl acrylamide) (TBA)) shell on mesoporous silica SBA-15 was obtained through free radical polymerization. Then, copper nanoparticles (CuNPs) decorated SBA-15/copolymer hybrid materials were synthesized using the NaBH4 reduction method. SBA-15 was functionalized with trimethoxylsilylpropyl methacrylate (TMSPM) and named TSBA. It was found that the CuNPs were uniformly dispersed in the mesoporous channels of SBA-15, and the hybrid catalyst exhibited excellent catalytic performance for the selective oxidation of different substituted benzyl alcohols in water using H2O2 as an oxidant at room temperature. The dual (temperature and pH-) responsive behaviors of the CuNPs/p(DMAEMA-co-TBA)/TSBA catalyst were investigated using the dynamic light scattering technique. The conversion of catalytic products and selectivity were calculated using gas chromatographic techniques, whereas the molecular structure of the products was identified using H-1 and C-13 nuclear magnetic resonance (NMR) spectroscopy. The catalyst showed excellent catalytic activity toward the oxidation of alcohol to aldehyde in an aqueous medium below the lower critical solution temperature (LCST) and pKa values (7-7.5) of the copolymer. The main advantages of the hybrid catalyst, as compared to the existing catalysts, are outstanding alcohol conversion (up to 99%) for a short reaction time (1 h), small amount of the catalyst (5 mg), and good recyclability equal to at least five times.

Superhydrophobic materials have attracted considerable scientific interest owing to their excellent properties such as self-cleaning ability, which are attractive for real-world applications. However, challenges still exist in realising smart superhydrophobic surfaces with reversible properties. Although there are many studies on reversible surfaces, most of them have tedious preparation processes or are difficult to achieve, in which the structure requires continuous stimuli to be maintained. Hence, we propose a novel and simple strategy to obtain superhydrophobic/hydrophobic reversible smart materials. Anthracene-terminated photo/thermo dual-response polyurethane was prepared as a dynamic substrate whose wrinkled structure could appear and disappear reversibly through dimerisation and depolymerisation of the anthracene groups. Thereafter, modified SiO2 sol was applied as the hydrophobic coating because the aggregation of SiO2 produces micro-nano structures on the surface wrinkles. The good synergistic effects of the wrinkles and nanoparticles enhance the roughness, realising superhydrophobic materials. These smart materials can reversibly convert into a hydrophobic or superhydrophobic wetting state, induced by UV exposure or heating, in which both states stable under normal conditions. Moreover, these superhydrophobic materials have many attractive properties, such as self-cleaning, durability, and environmental friendliness. The novel method used to fabricate dynamic wrinkles also has many potential applications in other areas such as triboelectric nanogenerator reversible switching of adhesion, and dynamic microfluidic channels.

The development of new fluorine-containing building blocks and their efficient synthetic access is currently a challenging research field. Herein, the highly regio- and stereoselective addition of a large range of aldehydes onto trifluoromethylated benzofulvenes was achieved using a simple La/I-2/DIBAL-Cl system via a selective C-F bond activation process. This versatile methodology provided homodienyl alcohols bearing a terminal CF2-alkene with potential further applications, as shown by the dehydration to the first benzofulvenes carrying a difluorovinyl group. In addition, for certain electron-poor aldehydes, unprecedented ipso substitution of the CF3 group in a diene was observed, which, according to DFT studies, is related to the presence of the large, Lewis-acidic lanthanum metal.

Zn(OAc)(2)-mediated Mannich-type reaction was studied for the synthesis of 3,3′-pyrrolidinyl-spirooxindole from L-2,3-dihydro-2-oxotryptophan methyl ester and aldehydes. The study indicates that the Mannich-type spirocyclization is significantly influenced by both the cation and anion of the metal salt, base, stoichiometry, stereoelectronics of aldehyde and temperature. With the enhancement by Zn(OAc)(2), the substrate induced asymmetric reaction works on both aromatic and aliphatic aldehydes but at different temperatures. It could deliver the (2’S,3R,5’S)-pyrrodinyl-spirooxindole with up to 96% of diastereomeric ratio in good yield under optimized conditions. (C) 2021 Elsevier Ltd. All rights reserved.

The stereoselective synthesis of terminal bromosubstituted propargylamines via in situ generation of lithium bromoacetylide from 1,2-dibromoethene and addition to Ellman chiral N-tert-butanesulfinyl aldimines is reported. Modest to good yields (43-85%) and diastereoselectivity (dr = 3:1 to >20:1) were achieved for a range of aryl, heteroaryl, alkyl, and alpha,beta-unsaturated substrates. Terminal bromo-substituted propargylamines prepared via this method can be directly used in the frequently employed Cadiot-Chodkiewicz coupling to produce functionalized diynes. The method reported here increases the structural diversity of chiral terminal bromo-substituted propargylamines that can be readily synthesized as previous methods for the stereoselective synthesis of these compounds rely on amino acid precursors from the chiral pool.

A highly modular radical cascade strategy based upon radical cyclisation/allylic substitution sequence between alkyl/aryl bromides, 1,3-dienes and nucleophiles ranging from sulfinates to amines, phenols and 1,3-dicarbonyls is described (>80 examples). Palladium phosphine complexes – which merge properties of photo- and cross coupling-catalysts – allow to forge three bonds with complete 1,4-selectivity and stereocontrol, delivering highly value added carbocyclic and heterocyclic motifs that can feature – inter alia – vicinal quaternary centers, free protic groups, gem-difluoro motifs and strained rings. Furthermore, a flow chemistry approach was for the first time applied in palladium-photocatalysed endeavors involving radicals.
