In this work, a monomer-mediated in situ growth strategy was developed for the controllable construction of core-shell Co3O4@TAPB-DMTP-COF composite (TAPB, 1,3,5-tris(4-aminophenyl)benzene; DMTP, 2,5-dimethoxyterephaldehyde; COF, covalent organic framework), which exhibits uniform size, high surface area, outstanding thermochemical stability, and ultrahigh effective surface area. The Co3O4@TAPB-DMTP-COF was further applied to develop an electrochemical sensor for the sensitive and selective determination of tertbutylhydroquinone (TBHQ). Mechanism investigations reveal that multistacked columnar channels given by TAPB-DMTP-COF shell can effectively facilitate the diffusion of TBHQ molecules to the active Co3+ sites. Under the optimal conditions, the current response exhibits two linear dynamic ranges, 0.05-1.0 and 1.0-400 mu mol L-1, and the detection limit was as low as 0.02 mu mol L-1 (S/N = 3). Little to no interference effects from other coexisting ions allows the sensor to detect low-abundance TBHQ from complicated real samples. This study not only provides a strategy for crystalline and shape-tailored growth of COF shells, but also expands their further use in electrochemical sensor.

A rhodium(III)-catalyzed redox-neutral coupling of alpha-trifluoromethylacrylic acid with bezamides proceeds smoothly accompanied by amide-directed C-H bond cleavage to produce beta-[2-(aminocarbonyl)phenyl]-alpha-trifluoromethylpropanoic acid derivatives. One of the products can be transformed to a trifluoromethyl substituted heterocyclic compound. In addition, the redox-neutral coupling of alpha-trifluoromethylacrylic acid with related aromatic substrates possessing a nitrogen-containing directing group can also be conducted under similar conditions.

The search of novel mPGES-1 inhibitors has recently intensified probably due to the superior safety in comparison to existing anti-inflammatory drugs. Although two mPGES-1 inhibitors have entered clinical trials, none has yet reached the market. In this study, we performed modifications guided by 3D-QSAR CoMFA on 2, which is an unsymmetrical curcumin derivative with low binding affinity towards mPGES-1. To counter the PAINS properties predicted for 2, the diketone linker was replaced with a pyrazole ring. On the other hand, both prenyl and carboxylate ester groups were introduced to improve the activity. When tested in vitro, 11 suppressed PGE(2) biosynthesis in activated macrophages and showed promising human mPGES-1 inhibition in microsomes of interleukin-1 beta-stimulated A549 cells. Altogether, 11 has been identified as a potential mPGES-1 inhibitor and could be a promising lead for a novel class of mPGES-1 inhibitors. (C) 2019 Elsevier B.V. All rights reserved.

The studies culminating in the synthesis of two large subunits of tautomycetin are described. The first one, fragment C1-C12 that has an anti-1,3-dimethyl system and a terminal diene unit, was accomplished in 10 linear steps in 7.4% overall yield. The second one, fragment C13-C25 which bears the sensitive anhydride framework and the majority of the stereogenic centers, was prepared in 13 linear steps (longest sequence) in 8% overall yield. Among the key transformations used, a regioselective epoxide opening, a Pd-catalyzed addition of terminal alkyne to acceptor alkyne, a Mukaiyama aldol reaction, a Yamaguchi esterification, and a homemade mild di-esterification can be cited. The chosen strategies allowed good yields, stereoselectivity, reproducibility, and scalability for several important intermediates.

Acylphosphonates having the 5,5-dimethyl-1,3,2-dioxophosphinanyl skeleton are developed as efficient intermolecular radical acylation reagents, which enable the cobalt-catalyzed Markovnikov hydroacylation of unactivated alkenes at room temperature under mild conditions. The protocol exhibits broad substrate scope and wide functional group compatibility, providing branched ketones in satisfactory yields. A mechanism involving the Co-H mediated hydrogen atom transfer and subsequent trapping of alkyl radicals by acylphosphonates is proposed.

The oxidative cross-coupling between the alpha-C(sp(3))-H bond of amide in DMAc and the inert ortho-C(sp(2))-H bond of benzamides is achieved for the first time by nickel catalysis, with the assistance of 8-aminoquinolyi group in the presence of a silver oxidant. Notably, the selectivity of conversion can be perfectly controlled by modulating the oxidant additives, and the products from the coupling of the C(sp(3))-H bond adjacent to nitrogen of amides with benzamides are approached through the use of peroxide.

Sulfuric acid and aromatic compounds are abundant in the atmosphere and play an important role in aerosol nucleation and growth. The main objective of this work is to provide molecular level description of pre-nucleation clusters formed by these species. Our approach is based on size- and compositionselective generation of anionic clusters, consisting of sulfuric acid and series of aromatic carboxylates (ArCOO-; Ar =Phenyl, o-, m-, and p-CH3C6H4 ), and their subsequent characterization using photoelectron spectroscopy and quantum chemical calculations. The photoelectron spectra show that formation of these clusters is accompanied by a significant increase of electron binding energies, implying significant stabilization gained from electron delocalization upon complexation. Comparison between the experimental and calculated results suggests that under low temperature conditions these clusters behave more like a complex of sulfuric acid and aromatic carboxylate, (H2SO4)(ArCOO-), despite the fact that ArCOO- has much higher proton affinity than HSO4-. Similar result has been previously reported for sulfuric acid formate cluster [Hou, Wang, and Valiev, J. Am. Chem. Soc. 139 (2017) 11321-11324], and indicates that interaction energy gained though the formation of these clusters is sufficient to counteract proton affinity imbalance. The calculated intermolecular binding energies (BEs), Gibbs free energies (Delta G), and evaporation rates (gamma) show that these (H2SO4)(ArCOO- ) clusters are extremely stable, with BEs of similar to 54 kcal/mol, Delta G of similar to-40 kcal/mol, and gamma of 10(-20) s(-1) . The experimental and computational results reported in this work suggest that aromatic acids may play a significant role in facilitating the early stages of sulfuric acid nucleation.
