Toward Chromoselective Transformations in Biological Systems: Perspectives and Challenges

Angewandte Chemie International Edition, Volume 65, Issue 31, 27 July 2026.
Controlling biological systems with small‐molecule chromophores has evolved into a powerful strategy and is applied from chemical biology to medicine. However, the complexity of in vivo systems cannot be matched by a single wavelength of light. Developing methods to combine and individually control multiple chromophores is crucial.

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.

Versatile Palladium‐Catalyzed C‐H Arylation of Fluoroarenes with 2‐Chloropyridine Derivatives

Chemistry – A European Journal, Volume 32, Issue 28, 25 July 2026.
Direct C─H arylation of fluoroarenes with 2‐chloropyridines is enabled by a simple Pd/SPhos system in isopropyl acetate. The method uses inexpensive reactants and shows broad scope and high yields. DFT computations explain reactivity and selectivity.
