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

open access: yesJournal 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 ...

Complete Series of 1,2‐Bis(trihalogenosilyl)benzenes (F, Cl, Br, I): A Platform for Cooperating Lewis‐Acidic Sites in Close Quarters

open access: yesZeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 2, 5 February 2026.
The complete series of 1,2‐bis(trihalogenosilyl)benzenes with F, Cl, Br, and I is synthesized and structurally characterized. The fluorinated compound binds up to two F− ions, one of them in a bridging mode. BBr3‐induced cyclization of an alkoxylated precursor affords a tetrahalogenated 1,3‐disila‐2‐oxaindane, highlighting cooperative reactivity of ...

Exploring the World of Double Nanohoops

open access: yesAngewandte Chemie International Edition, Volume 65, Issue 6, 2 February 2026.
As two conjugated nanohoops covalently linked by a central unit, double nanohoops are a relatively new class of strained nanocarbons with different properties to single nanohoops. This review gives an overview of all reported double nanohoops, categorizing their structures, syntheses, and discussing properties and applications. Creativity and synthetic
