A modified C-18 column (Silpr-2MI-C18) was prepared using 2-methylindole and C-18 reagent. The extent of C-18 hydrocarbon chain, conjugative rings and anion exchange site provided multiple retention mechanisms, including reversed-phase liquid chromatography (RPLC), pi-pi interaction, hydrophilic interaction liquid chromatography (HILIC) and anion exchange chromatography (AEC). The separation of protected amino acids was investigated on the commercial C-18 and Silpr-2MI-C18 columns, while the chromatographic conditions, including methanol content and pH of the mobile phase, were studied. The separation arrangement of the hydrophilic amino acids was different on the Silpr-2MI-C18 column compared to the commercial C-18 column under RPLC mode. Furthermore, these amino acids were separated on the Silpr-2MI-C18 column under HILIC mode. The modified C-18 column was employed to separate amino acids, alkylbenzenes and polycyclic aromatic hydrocarbons under RPLC mode and inorganic anion under AEC mode. The results confirm that this new stationary phase of RPLC/HILIC/AEC has multiple interactions with different analytes. Effective retention of biological samples was found on the Silpr-2MI-C18 column by comparing the results obtained from the commercial C-18 column.

A redox-active iminoquinone motif connected with pi-delocalized pyrene core has been reported that can perform efficient two-electron oxidation of a class of substrates. The design of the molecule was inspired by the organic redox cofactor topaquinone (TPQ), which executes amine oxidation in the enzyme, copper amine oxidase. Easy oxidation of both primary and secondary alcohols happened in the presence of catalytic KOtBu, which could reduce the ligand backbone to its iminosemiquinonate form under photoinduced conditions. Moreover, this easy oxidation of alcohols under aerobic condition could be elegantly extended to multi-component, one-pot coupling for the synthesis of quinoline and pyrimidine. This organocatalytic approach is very mild (70 degrees C, 8 h) compared to a multitude of transition-metal catalysts that have been used to prepare these heterocycles. A detailed mechanistic study proves the intermediacy of the iminosemiquinonate-type radical and a critical hydrogen atom transfer step to be involved in the dehydrogenation reaction.

A green method for the oxidation of alcohols to carboxylic acids was developed using a novel co-catalytic system based on gold, silver, and copper catalysts. This reaction system was conducted under atmospheric oxygen in water and mild conditions to selectively oxidize 5-hydroxymethylfurfural to 2,5-furandicarboxylic acid, as a building block for polyethylene furanoate, which is a 100% bio-based, future alternative to the petroleum-based polyethylene terephthalate. Furthermore, various primary alcohols were conveniently oxidized to their corresponding carboxylic acids in up to quantitative yields.

Herein, we report a combination of pyrenedione (PD) and KO’Bu to achieve facile alcohol dehydrogenation under visible-light excitation, where aerobic oxygen is utilized as the terminal oxidant. The resulting carbonyl compound can be easily converted to vinyl nitriles in a single-pot reaction, at 60 degrees C in 6-8 h. This environmentally benign, organocatalytic approach has distinct advantages over transition-metal-catalyzed a-olefination of nitriles, which often operate at a significantly higher temperature for an extended reaction time.

A series of metal niobates (MNb2O6, M = Zn2+, Ni2+ and Co2+) were prepared from H-niobate precursor under hydrothermal conditions, in which amino groups of L-lysine play an important role. Au nanoparticles were then supported on these niobates by NaBH4 reduction method. More importantly, the strong interaction between Au nanoparticles and ZnNb2O6 generates negatively charged Au which can activate molecular oxygen to form the exclusive high-active peroxide (NbOOAu) species on Au/ZnNb2O6 surface under visible light irradiation, observed in situ by diffuse reflectance infrared Fourier transform spectra (DRIFTS). The optimal NbOOAu species produced on the surface of Au/ZnNb2O6 can remove the H atom of the methylene group (-CH2-) of benzyl alcohol, leading to high photocatalytic activity of Au/ZnNb2O6 compared with Au/NiNb2O6 and Au/CoNb2O6. This modulation of interaction of Au and niobates for the activation of molecular oxygen provides a new prospect for highly selective photocatalytic oxidation reactions.

The enhancement of reactivity inside supramolecular coordination cages has many analogies to the mode of action of enzymes, and continues to inspire the design of new catalysts for a range of reactions. However, despite being a near-ubiquitous class of reactions in organic chemistry, enhancement of the reduction of carbonyls to their corresponding alcohols remains very much underexplored in supramolecular coordination cages. Herein, we show that encapsulation of small aromatic aldehydes inside a supramolecular coordination cage allows the reduction of these aldehydes with the mild reducing agent sodium cyanoborohydride to proceed with high selectivity (ketones and esters are not reduced) and in good yields. In the absence of the cage, low pH conditions are essential for any appreciable conversion of the aldehydes to the alcohols. In contrast, the specific microenvironment inside the cage allows this reaction to proceed in bulk solution that is pH-neutral, or even basic. We propose that the cage acts to stabilise the protonated oxocarbenium ion reaction intermediates (enhancing aldehyde reactivity) whilst simultaneously favouring the encapsulation and reduction of smaller aldehydes (which fit more easily inside the cage). Such dual action (enhancement of reactivity and size-selectivity) is reminiscent of the mode of operation of natural enzymes and highlights the tremendous promise of cage architectures as selective catalysts.

The traditional Staudinger/aza-Wittig reaction represents one of the most powerful tools for imine formation. However, for this multistep procedure, the sacrificial phosphine has to be used, resulting in difficulties in the purification process and waste disposal at the same time. Here, we report a redox-neutral azide-alcohol imination methodology enabled by a base-metal nickel PN3 pincer catalyst. The one-step, waste-free, and high atom-economical features highlight its advantages further. Moreover, mechanistic insight suggests a non-metal-ligand cooperation pathway based on the observation of an intermediate and density functional theory calculations.

Two high-resolution mass spectrometers (HRMS) with different analyzer technology, Orbitrap and hybrid quadrupole time-of-flight (QTOF), were compared with a low-resolution mass spectrometer, quadrupole, to analyse a set of 35 difficult allergens. These difficult allergens are commonly coeluted fragrance allergens with matrix compounds, using standard gas chromatography-mass spectrometer conditions, from the extended list of the Scientific Committee on Consumer Safety (SCCS). Although the fundamental role of chromatographic separation has been demonstrated many times, the aim of this work is to demonstrate the benefits of high-resolution. The added value of high-resolution was illustrated in both a qualitative and a quantitative way. For qualitative aspect, the high resolution extracted ion signals of these two detectors were compared with the low-resolution extracted ion signals. About 50% of the coeluted cases observed with the low-resolution detector are easily resolved by the two high-resolution detectors. For the quantitative aspect, an accuracy profile methodology and a performance metric were used to propose an overall evaluation. The Orbitrap mass spectrometer demonstrated a better overall performance, while the QTOF presented similar or even lower quantification performances than the quadrupole on the set of analysed fragrances.

Our laboratory has developed catalysts based on earth abundant titanium for asymmetric reactions including intramolecular hydroamination. Previously, we showed that titanium complexes of imine diol ligands showed improved enantioselectivity relative to complexes with bidentate amino alcohol ligands. As the catalyst with the highest selectivity had di-tert-butyl substitution, we sought to increase the steric protection by preparing three new ligands with diaryl substitution. These ligands were readily prepared in two steps: first, synthesis of diaryl substituted salicylaldehydes by a Suzuki coupling and second, a Schiff base condensation with a chiral amino alcohol. After characterizing the ligands, in situ hydroamination/cyclization with 6-methyl-hepta-4,5-dienylamine was carried out at temperatures ranging from 105 degrees C to 135 degrees C to give exclusively 2-(2-methyl-propenyl)-pyrrolidine with enantioselectivity up to 22 %ee. Unexpected dimerization of the catalyst resulted in reduced activity, so the reaction required a catalyst loading of 10-20%. (C) 2021 Elsevier Ltd. All rights reserved.
