Summary: In this study, a highly atom- and step-economical stereoselective synthesis of E-dienyl esters is reported. This approach involves rhodium catalysis and utilizes carboxylic acid and acetylene as C2 synthon through a cascade of cyclometalation and C-O coupling. The protocol demonstrates mild conditions, excellent functional group tolerance, exclusive E-stereoselectivity, and proves useful for late-stage modification of pharmaceuticals and natural products.

Summary: We report a new synthetic protocol for the selective perfluoro-tert-butylation of arenes. By using PFtB phenyl sulfone as a source of PFtB anion, highly regioselective reactions with arynes can yield perfluoro-tert-butylated arenes with high yields. The method is demonstrated by the preparation of sensitive 19F-labeled NMR probes with exceptional resolving ability.

Summary: Microbial-based pigments, such as astaxanthin and β-carotene produced by P. rhodozyma, have attracted attention as greener and more effective alternatives in the cleaning and cosmeceutical industries. However, the optimization of downstream processing operations for carotenoid recovery from P. rhodozyma has not been fully achieved. This study proposes a sustainable one-pot process using biocompatible and renewable solvents for the recovery of astaxanthin and β-carotene from P. rhodozyma biomass and formulation of bioactive soaps.

Summary: Hierarchically ordered chiral crystals have been the focus of intensive research efforts due to their potential applications in optical devices, asymmetric catalysis, and pharmaceutical crystal engineering. However, the use of expensive enantiomerically pure building blocks and the challenge of precise control over chirality transfer have hindered their practical application. A new strategy described in this study offers a solution by enabling the preferred formation of one enantiomorph from a racemic solution and subsequent enantiomer-specific oriented attachment through a balance of stereoselective and non-stereoselective interactions. This methodology allows for the efficient fabrication of homochiral organic crystals from racemic starting materials, demonstrating the potential for immediate practical use.

Summary: A method for preparing alpha-chiral carboxylic acid derivatives, including those with all-carbon quaternary centers, was reported through an enantioselective CuH-catalyzed hydrocarboxylation of allenes with a commercially available fluoroformate. Various heterocycles and functional groups on the allenes were tolerated, resulting in enantioenriched alpha-quaternary and tertiary carboxylic acid derivatives with good yields and exclusive branched regioselectivity. The synthetic utility of this approach was further demonstrated by derivatization of the products to obtain biologically important compounds, such as the antiplatelet drug indobufen.

Summary: Protein-polymer conjugation is a useful approach to improve protein stability and performance, but polymer-polymer interactions can also affect the properties of polymer-modified proteins. This study demonstrates that by adjusting the ratio of polymers, the productivity of lipase can be optimized, although this may lead to a trade-off between activity and stability.

Summary: Here, we present a decarboxylative Minisci hetero-arylation study at the bridge positions. Through a simple and photocatalyst-free process, free bridge carboxylic acids are directly coupled with nonprefunctionalized heteroarenes to yield polysubstituted BCP and oBCH derivatives in high yields. Furthermore, the impact of the BCP core on the physicochemical properties of a representative example compared to its all-aromatic ortho- and meta-substituted analogues is evaluated.

Summary: This study demonstrates, for the first time, the ability to use light to distinguish between ketones and carboxylic acids in more complex molecules. By utilizing different activation modes, a single catalytic system can be used for hydroboration, with chemoselectivity dictated solely by the presence or absence of visible light.

Summary: This study proposes using 1,4-benzenedithiol and benzeneselenol as redox mediator additives in the electrolyte of a lithium-selenium battery. By changing the reaction process of selenium and accelerating redox kinetics, the shuttle effect of polyselenides is suppressed, leading to improved cycling stability and rate performance. The different molecular structures of 1,4-benzenedithiol and benzeneselenol result in different mechanisms that enhance cycling stability and kinetic performance, respectively.

Summary: In this study, a layered carbon dot composite catalyst (NiFe LDH@CDs) was prepared using a one-step coprecipitation method, without the need for heating or hydrothermal treatment. The CD-functionalized catalyst facilitated rapid charge transfer and accelerated the oxygen evolution reaction. Additionally, the heterojunction structure formed between NiFe LDH and CDs efficiently suppressed photoelectron-hole recombination.

Summary: We designed and synthesized a NN-CoII bidentate complex and used it for the amination of alcohols under mild and solventless conditions. The complex exhibited good reactivity towards both primary and sterically hindered secondary alcohols, providing high yields of amines. The pyrazole moiety in the ligand played a crucial role in the reaction. Furthermore, we demonstrated the reusability of the complex as a homogeneous cobalt catalyst.

Summary: Replicating the enzymatic surface microenvironment in vitro is challenging, but constructing an analogous model could facilitate our understanding of surface effects and aid in developing an efficient bioinspired catalytic system. In this study, five unique Cu2O morphologies were generated, and the surface morphology variations were found to be a consequence of differences in the exposure of low-index facets. The reactivity of Cu2O was found to be influenced by the proportion of {110} planes, with r-Cu2O exhibiting the highest reactivity.

Summary: This article reports a transition-metal-free process for in situ denitrogenation of tosylhydrazones, resulting in the production of various sulfones. The authors used a phenalenyl-based odd alternant hydrocarbon as a photoredox catalyst, which acted as a potent oxidant to facilitate the denitrogenation reaction. The method showed wide functional-group tolerance and high yields, making it suitable for late-stage modification of natural products.
