3‐Deoxy‐3‐Fluoro Mannuronic Acid Alginates: Stereoselective Automated Synthesis and Conformational Behaviour

Angewandte Chemie, Volume 138, Issue 31, 27 July 2026.
The impact of C‐3 fluorination on the synthesis and conformation of alginate oligosaccharides is investigated. A C‐3‐fluoro mannuronic acid building block is generated and shown to react with high β‐selectivity. Automated glycan assembly enables access to uniquely fluorinated mannuronic acid alginates where deoxyfluorination is shown not to perturb the

Unraveling the Role of Lignin Oligomers Functionality for the Synthesis of Nonisocyanate Polyurethanes

ChemSusChem, Volume 19, Issue 15, 14 August 2026.
This study reports the synthesis of bio‐based nonisocyanate polyhydroxyurethanes from crude lignins and depolymerized lignin oligomers. The structure–properties relationships were largely explored and highlighted the key role of lignin functionality on the physical properties of the materials. Lignins are the main source of aromatic compounds in nature.

Design and Characterization of Dual‐Modal Fluorinated BODIPY Probes

ChemPlusChem, Volume 91, Issue 8, August 2026.
Here we show a fluorinated BODIPY dye that combine 19F traceability with photoluminescence, properly designed to reduce aggregation‐induced quenching and to adjust the packing in condensed environments. The molecule can be encapsulated in Pluronic F68‐stabilized poly(lactic‐co‐glycolic acid) nanoparticles.
