Surveying the Homogeneity of a Molecular Electrocatalyst Embedded in a Metal‐Organic Framework Using Operando Characterization

ChemSusChem, EarlyView.
A detailed study of the homogeneity changes exhibited by a molecular Cu catalyst embedded in a MOF during the oxygen reduction reaction. Operando X‐ray absorption spectroscopy reveals a transformation from a molecular Cu2+ catalyst to Cu0 clusters <2 nm, emphasizing the risk of attributing high catalytic performance to molecular catalysts that have ...

Electrochemical Sulfonylation in Deep Eutectic Solvents Enables the Sustainable Synthesis of 2‐Quinoline Sulfones

ChemSusChem, EarlyView.
The use of a deep eutectic solvent (DES) in sulfonylation electrosynthesis enables the high‐yield and scalable production of 2‐arylsulfonylquinolines without the need of volatile organic compounds. Acting as reaction medium and removing the need of a supporting electrolyte, the DES affords excellent yields across a broad scope of compounds, allows ...

Asymmetric Catalytic Hydrogenation toward a Value‐Added Chiral Building Block: Optically Active γ‐Butyrolactone Scaffold from Renewable and Synthetic Derived Feedstocks

European Journal of Organic Chemistry, EarlyView.
This brief compendium summarizes the most successful asymmetric hydrogenation strategies for the preparation of chiral monocyclic γ‐lactone derivatives from keto acids and keto esters, with emphasis on their relevance for large‐scale production and high enatioselectivities. This article provides a brief compendium on the production of chiral monocyclic

Cyclodextrin‐Encapsulated N‐Heterocyclic Carbene–Copper(I) Complexes for Homogeneous Catalysis in Pure Water: Anaerobic Oxidation of Arylboronic Acids with Water as the Formal Oxidant

European Journal of Organic Chemistry, EarlyView.
Cyclodextrin(CD)‐encapsulated N‐heterocyclic carbene (NHC)‐copper(I) complexes based on modified permethylated α or β CDs catalyze the ipso‐hydroxylation‐deborylation reaction of arylboronic acids in pure water at low copper loading. The reaction is favored by triethylamine and is compatible with various functionalized substrates.

Accelerating Enzyme Engineering With Artificial Intelligence in Biocatalysis: Challenges and Opportunities

Food Bioengineering, EarlyView.
ABSTRACT Artificial intelligence (AI) has emerged as a paradigm‐shifting force in enzyme engineering, enabling data‐driven prediction of catalytic activity, stability, and substrate specificity. By integrating large‐scale datasets from structured databases (e.g., PDB, BRENDA) and high‐throughput experimentation (e.g., deep mutational scanning ...
