Electrochemical carbon–carbon coupling with enhanced activity and racemate stereoselectivity by microenvironment regulation

Nature Communications, 2023
Enzymes are characteristic of catalytic efficiency and specificity by maneuvering multiple components in concert at a confined nanoscale space. However, achieving such a configuration in artificial catalysts remains challenging.

Structure- and Data-Driven Protein Engineering of Transaminases for Improving Activity and Stereoselectivity.

Angewandte Chemie, 2023
Amine transaminases (ATAs) are powerful biocatalysts for the stereoselective synthesis of chiral amines. Machine learning provides a promising approach for protein engineering, but activity prediction models for ATAs remain elusive due to the difficulty ...

Stereoselectivity in the Membrane Transport of Phenylethylamine Derivatives by Human Monoamine Transporters and Organic Cation Transporters 1, 2, and 3

Biomolecules, 2022
Stereoselectivity is well known and very pronounced in drug metabolism and receptor binding. However, much less is known about stereoselectivity in drug membrane transport. Here, we characterized the stereoselective cell uptake of chiral phenylethylamine

Integral Stereoselectivity of Lipase Based on the Chromatographic Resolution of Enantiomeric/Regioisomeric Diacylglycerols.

Journal of Agricultural and Food Chemistry, 2021
Stereoselectivity, a distinctive characteristic of lipase (EC 3.1.1.3), refers to the ability to differentiate between enantiomeric positions (sn-1 and sn-3) in triacylglycerol (TAG).

Palladium-catalyzed regio- and stereoselective alkoxycarbonylation of unsymmetrical internal alkynes toward α, β-unsaturated succinates

Tetrahedron Chem, 2022
Succinates play a vital role in industry, pharmaceutics, beverage, and cosmetics. A regio- and stereoselective alkoxycarbonylation of unsymmetrical internal alkynes with alcohols or phenols toward α, β-unsaturated succinates enabled by palladium ...

Stereoselective arene formation [PDF]

Chemical Society Reviews, 2018
The common perception of arenes as flat and symmetric entities is juxtaposed to the counterintuitive circumstance that stereoselective arene formation offers a means to prepare an exceptional range of chiral aromatic structures in isomerically enriched form.

Modifying Woodward–Hoffmann Stereoselectivity Under Vibrational Strong Coupling

Angewandte Chemie, 2020
Vibrational strong coupling (VSC) has recently been shown to change the rate and chemoselectivity of ground‐state chemical reactions via the formation of light–matter hybrid polaritonic states.
