Bridged biaryl atropisomers are important units in bioactive molecules. A synthesis of lactone-bridged biaryl atropisomers was realized by a Cu-catalyzed asymmetric ring-opening/acyoxylation of cyclic diaryliodoniums, followed by a palladium-catalyzed diastereoselective cyclization. It was found that a catalytic amount of Cu(OTf)(2) served as an additive to promote the palladium-catalyzed Heck cyclization.

A thorough study of mild and environmentally friendly electrochemical-induced hydroxylation of aryl halides without a catalyst is presented. The best protocol consists of hydroxylation of different aryl iodides and aryl bromides by water solution in the presence of Et3N under air, affording the target phenols in good isolated yields. Moreover, aryl chlorides were successfully employed as substrates. This methodology also provides a direct pathway for the formation of deoxyphomalone, which displayed a significant anti-proliferation effect.

An efficient and convenient rhodium(III)-catalyzed chelation-assisted ortho-selective carbon-hydrogen bond alkylation of phenols treated with readily available diazocarbonyl compounds as the alkyl source has been described. Migratory carbene insertion represents the principal step to realize this carbenoid coupling transformation, giving rise to a broad rang of alkylated products and at the same time, releasing nitrogen gas as sole byproduct. This protocol offers exclusive regioselectivities, moderate to excellent chemical yields, and good functional group tolerance.

Background: Flagellin of Salmonella enterica serovar Enteritidis (SEF) stimulates immune responses to both itself and coapplied antigens. It is therefore used in vaccine development and immunotherapy. Removal of pathogenic S. enterica ser. Enteritidis from SEF production process is advantageous due to the process safety improvement. The protein solubility analysis using SDS-PAGE indicated that 53.49% of SEF expressed in Escherichia coli formed inclusion bodies. However, the protein recovery from inclusion bodies requires a complex process with a low yield. Objective: We thus aim to study possibility of enhancing SEF expression in E. coli in soluble form using chemical and molecular chaperones. Methods: Chemical chaperones including arginine, sorbitol, trehalose, sodium chloride and benzyl alcohol were used as cultivation medium additives during SEF expression. SEF solubilization by coexpression of molecular chaperones DnaK, DnaJ, and GrpE was also investigated. Results: All of the chemical chaperones were effective in improving SEF solubility. However, sorbitol showed the most profound effect. SEF solubilization by molecular chaperones was slightly better than that using sorbitol and this approach enhanced noticeably SEF soluble concentration and SEF solubility percentage to almost two folds and 96.37% respectively. Results of limited proteolysis assay and native PAGE indicated similar conformational states and proper folding for SEF obtained without using chaperones and for those obtained using sorbitol and the molecular chaperones. However, the molecular chaperones based system was less costly than the sorbitol based system. Conclusion: The coexpression of molecular chaperones was then considered as the most appropriate approach for soluble SEF production. Therefore, SEF production for medical purposes is expected to be facilitated.

The oxidative cleavage of the C-N bond of aryl and heteroaryl (dimethylamino)methyl groups is achieved by employing molecular iodine as a mild oxidizing agent under ambient conditions in the presence of a mild base. The important reaction of C3 formylation of free NH and substituted indoles containing various substituents is accomplished from the corresponding Mannich bases. This methodology can also be extended for the synthesis of aryl and other heteroaryl aldehydes and ketones. Furthermore, the usefulness of the method is successfully demonstrated on a gram scale.

A new strategy is presented for enhancing the catalytic activity of cross-linked chitosan beads. More precisely, chitosan beads were cross linked with glutaraldehyde and then, vinyl functionalized. In the next step, the vinyl-functionalized beads were polymerized with the as-prepared 1-vinyl-3-butylimidazolium bromide to furnish polyionic liquid on beads. The resultant compositewas subsequently utilized as a metal-free catalyst for catalyzing some classic organic transformations, including Knoevenagel condensation reaction and syntheses of tetrahydrobenzo[b]pyrans and pyrano[2,3-d]pyrimidines in aqueous media under mild reaction conditions. It was found that the novel composite could efficiently promote all of the examined reactions to afford the corresponding products in high yields. Moreover, the catalyst exhibited high recyclability for all reactions. The comparative studies also approved that the activity of the composite was superior compared to cross-linked bead and polyionic liquid. (C) 2021 Elsevier B.V. All rights reserved.

Catalysis is the second largest application for V after its use as an additive to improve steel production. Molecular complexes of vanadium(V) are particularly useful and efficient catalysts for oxidation processes; however, their ability to catalyze reductive transformations has yet to be fully explored. Here we report the first examples of polar organic functionality reduction mediated by V. Open-shell V-III complexes that feature a pi-radical monoanionic 2,2′:6′,2 ”-terpyridine ligand (Rtpy(center dot))(-) functionalized at the 4′-position (R = (CH3)(3)SiCH2, C6H5) catalyze mild and chemoselective hydroboration and hydrosilylation of functionalized ketones, aldehydes, imines, esters, and carboxamides with turnover numbers (TONs) of up to similar to 1000 and turnover frequencies (TOFs) of up to similar to 500 h(-1).Computational evaluation of the precatalyst synthesis and activation has revealed underappreciated complexity associated with the redox-active tpy chelate.
