Making Blank Faces Expressive: Chemical Approaches to the Modification of Chemically Inert Peptides

Journal of Peptide Science, Volume 32, Issue 3, March 2026.
As an alternative to the conventional approach, which combines amino acid monomers in a one‐by‐one fashion to peptide derivatives, the chemical modification of existing peptides has attracted significant attention in recent years. However, such approaches generally target the reactive functional groups in cysteine and lysine residues, particularly in ...

Synergistic Effects of Electricity and Light for Efficient Iron‐Catalyzed Recycling of Polystyrene Waste

Angewandte Chemie International Edition, Volume 65, Issue 7, 9 February 2026.
The synergistic interplay of electricity, light and earth‐abundant, nontoxic iron catalysis allowed for the efficient recycling of post‐consumer polymers into value‐added products. This robust depolymerization strategy was viable on multigram‐scale, where the cathodic hydrogen evolution reaction presents an attractive opportunity for a green hydrogen ...

Alkynyltriazenes in Photochemical Metal‐Free Doyle–Kirmse Rearrangements

Angewandte Chemie International Edition, Volume 65, Issue 7, 9 February 2026.
A metal‐ and additive‐free photocatalytic Doyle–Kirmse reaction of alkynyl triazenes is described, proceeding via cyanocarbene intermediates. This strategy enables the efficient construction of highly substituted asymmetric carbon centers with broad substrate scope, delivering synthetically valuable nitriles.

Ring Formation in Sesquiterpene Synthesis: Biomimetic vs. Non‐Biomimetic Strategies

European Journal of Organic Chemistry, Volume 29, Issue 5, 7 February 2026.
A short review of cyclase enzyme‐mediated ring formation in sesquiterpene biosynthesis is presented as a prelude to six case studies examining the merits and demerits of biomimetic vs. non‐biomimetic strategies for carbocyclisation in the total synthesis of this iconic natural product class.
