To obtain a pure product without the isomer byproducts is a goal that many chemists are pursuing. As one kind of very important synthesis method, the photochemical reaction is simple and straightforward yet low-selective. In this work, a coordination interaction based oriented synthesis strategy has been proposed to realize the precise stereochemical control of the isomeric cyclic compounds in the photocycloaddition reaction. Through fixing the reactants via coordination interactions, the arrangements and configurations of the reactants can be adjusted, thereby successfully producing all of the related photocycloaddition products without isomer byproducts for the first time. This work not only provides a new route to synthesize the pure cyclic compounds but also expands the application of the photocycloaddition reaction.

Basicity is an important parameter with impact on biological systems and technological problems. The HOMO-LUMO and FERMO theoretical approaches can describe the acid-base behavior of compounds as amines, carboxylic acids and alcohols. In this work, a method was developed using the localization degree Gamma(FERMO) parameter based on projection operators to quantify the localization of molecular orbitals. This new method was employed for the analysis of the protonation reaction of 30 organic compounds. The quantitative data from our findings were able to reproduce experimental data, pointing out that the FERMO approach could better describe the acid-base behavior of the investigated compounds.

We described the chemical synthesis of a sulfated trisaccharide repeating unit of fucosylated chondroitin sulfate (FCS), which has significant anticoagulant activity. Well-functionalized monosaccharides were readily prepared, and highly efficient glycosylations using a common activator (NIS/ TfOH) were also presented. The synthesized trisaccharide 4 could be used to extend oligosaccharide sequences.

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.

I found the field of Chemistry very interesting. Saw the article Design and synthesis of a novel mPGES-1 lead inhibitor guided by 3D-QSAR CoMFA published in 2019. COA of Formula: C14H10O3, Reprint Addresses Aluwi, MFFM (corresponding author), Univ Malaysia Pahang, Fac Ind Sci & Technol, Gambang 26300, Pahang, Malaysia.; Wai, LK (corresponding author), Univ Kebangsaan Malaysia, Fac Pharm, Drug & Herbal Res Ctr, Jalan Raja Muda Abdul Aziz, Kuala Lumpur 50300, Malaysia.. The CAS is 93-97-0. Through research, I have a further understanding and discovery of Benzoic anhydride

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.

Authors Chen, YL; Xie, Y; Sun, X; Wang, Y; Wang, Y in ELSEVIER SCIENCE SA published article about in [Chen, Yuling; Xie, Yao; Sun, Xin; Wang, Yang] Yangzhou Univ, Sch Chem & Chem Engn, Yangzhou 225002, Jiangsu, Peoples R China; [Wang, Yi] Wenzhou Med Univ, Sch Ophthalmol & Optometry, Sch Biomed Engn, Wenzhou 325027, Peoples R China in 2021.0, Cited 37.0.

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 metal-free aromatic electrophilic substitution reaction using nitrosoarenes as the electrophile in 1,1,1,3,3,3-hexafluoroisopropanol (HFIP) is reported. HFIP activates nitrosoarene towards the electrophilic C-H amination followed by a concomitant N-O bond cleavage to deliver diarylamines without requiring any extra reagent or further treatment. The dual electrophilic nature of nitrosoarene permits a switchover of selectivity to C-H oxygenation furnishing dearomatizedp-iminoquinones following a unique mechanistic rationale of two consecutive [2,3] sigmatropic rearrangement in nitroso-chemistry.

Nano copper ferrite catalyst is prepared and characterized by scanning electron microscopy, energy dispersive X-ray, X-ray diffraction, vibrational sample magnetometry, and Fourier transform infrared. The catalytic activity is probed for cross-dehydrogenative coupling of aromatic aldehydes in the presence of tert-butyl hydroperoxide as the oxidant. This catalytic protocol appears as a simple, rather cheap, clean, and efficient practical strategy for the synthesis of symmetrical anhydrides, with proper efficiency (66%). The catalyst can be easily separated from the reaction mixture by an external magnet and reused several times in subsequent reactions, without any measurable loss of its efficiency. [GRAPHICS] .
