Late‐Stage Functionalization of Peptides on the Solid Phase

Angewandte Chemie International Edition, Volume 65, Issue 31, 27 July 2026.
Peptide modifications are essential to control pharmacodynamic and pharmacokinetic properties of peptide drugs. Consequently, strategies that allow for efficient and rapid incorporation of non‐canonical modifications into peptides in parallel formats are highly sought after.

Methyl on the Bridge: 2‐Methyl Propellane as Precursor for 1,3‐Substituted 2‐Methylated Bicyclo[1.1.1]Pentanes

Chemistry – A European Journal, Volume 32, Issue 28, 25 July 2026.
The synthesis of 2‐methyl propellane and its conversion to various 1,2‐ and 1,2,3‐di‐ and trisubstituted bicyclopentanes is reported. Abstract Bicyclo[1.1.1]pentanes (BCPs) have emerged as isosteric replacements for mono‐ and para‐substituted benzene rings in medicinal and materials applications, involving substitution at the BCP bridgehead (1,3 ...

Synthesis of Benzopyran Atropisomers via Electrophilic Halogenation

European Journal of Organic Chemistry, Volume 29, Issue 27, 17 July 2026.
We report a halogenation‐based method for the synthesis of axially chiral benzopyrans, tolerating diverse substituents and halogens (Br, Cl, and I). A double bromination gives bisbenzopyrans with two stereogenic axes. Preliminary enantioselective conditions yield benzopyran atropisomer with up to 56% ee.
