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

Acetylation‐Deacetylation‐Driven Natural Product Biosynthesis

open access: yesChemistryEurope, EarlyView.
This review summarizes the role of acetylation‐deacetylation in natural product biosynthesis, including acetylation followed by deacetylation after several biosynthetic steps, acetylation‐mediated rearrangement, acetylation‐triggered elimination, and the acetylation cycle as a regulatory mechanism. These processes are vital for the formation of complex
