Single‐Step Synthesis of Dithieno[3,2‐b:2′,3′‐e]Pyridines and Their Acid‐Dependent Optical and Photosensitising Properties

Chemistry – A European Journal, Volume 32, Issue 34, 11 September 2026.
The synthesis of dithieno[3,2‐b:2′,3′‐e]pyridines (DTPs) is herein reported, and their optical properties are studied both experimentally and computationally. Protonation or methylation of the nitrogen atom induced bathochromic shifts in their absorption and emission spectra.

Precision Chemistry for Protein Lysine Modification

Chemistry – A European Journal, Volume 32, Issue 34, 11 September 2026.
Selective modification of lysine residues is challenging due to their similar intrinsic reactivity. Inspired by enzymatic recognition, ligand‐guided electrophiles enable site‐selective labeling and functionalization, while ligand‐guided catalyses achieve regioselective installation of bio‐relevant post‐translational modifications.
