C‐Terminal Functionalization Methods of Amino Acids, Peptides, and Proteins

open access: yesChemistry – A European Journal, EarlyView.
C‐terminal functionalization offers powerful routes to peptide and protein diversification, yet epimerization, hydrolysis, and selectivity remain key challenges. This Review surveys enzymatic, decarboxylative, and condensation strategies, highlighting advances toward chemo‐ and regioselective, protecting‐group‐free, atom‐efficient methods applicable to

Alkyne‐Assisted Stereospecific Skeletal Rearrangement via Nonclassical Carbocations

open access: yesChemistry – A European Journal, EarlyView.
We report stereospecific nucleophilic substitution of homopropargylic alcohols enabled by alkyne anchimeric assistance. Alcohol activation triggers formation of a nonclassical cyclopropylidenemethyl cation, allowing efficient chirality transfer to densely substituted tertiary homopropargyl fluorides.
