Merging Peptide and Enzyme Catalysis in a Single Protein Domain Bearing Two Separated Active Sites

open access: yesChemCatChem, EarlyView.
A dual‐functional catalyst that unites peptide catalysis and biocatalysis within a single protein scaffold at two distinct active sites offers a promising strategy for cascade catalysis. This hybrid catalyst enabled here a one‐pot transformation of alcohols to C─C coupled products via enamine activation, revealing challenges such as mismatched reaction

Advances in Ligand‐Driven Pd‐Catalyzed C─H Functionalizations: Recent Insights and Updates

open access: yesChemCatChem, EarlyView.
The most significant advances in ligand‐driven Pd‐catalyzed organic synthesis over the past two years are presented. Processes involving C─H activation of substrates, avoiding their prefunctionalization are illustrated. Both the activity and selectivity of the catalyst depend on the design of the ligands (pyridones, pyridines, amino acids, phosphines ...

An Alternative Mechanistic Paradigm for the Electrochemical C‐Terminal Decarboxylation of Peptides

open access: yesChemElectroChem, EarlyView.
Chemoselectivity in electrochemical oxidations is largely influenced by oxidation potential which represents a challenge for selectively oxidizing higher potential functional groups in complex substrates. Herein, a molecular binding strategy that selectively oxidizes the C‐terminal acid of a model peptide containing an electron‐rich tyrosine residue by
