Streamlined One‐Pot Synthesis of Fused Pyrroles: A Three‐Component Approach

open access: yesChemistryOpen, Volume 15, Issue 4, April 2026.
New modified pyrrole derivatives, namely tetrahydroindol‐4‐ones and pyrrolo[2,3‐d]pyrimidines, functionalized at position 3, were synthesized through a one‐pot multicomponent condensation. Stabilized dimedone enaminones derived from α‐amino acids and their esters (or 6‐amino‐1,3‐dimethyluracil), arylglyoxals, and methylene‐active compounds ...

Surface Functionalization of Polyetheretherketone With Immobilized γ‐Polyglutamic Acid for Enhanced Apatite Formation

open access: yesChemistryOpen, Volume 15, Issue 4, April 2026.
The authors developed chemical solution process to immobilize γ‐polyglutamic acid (γ‐PGA) onto polyetheretherketone (PEEK). Prior hydrophilic treatment using UV irradiation improved the immobilization efficiency of γ‐PGA and the apatite‐forming ability in simulated body fluid compared with acetic acid treatment.

Biocatalysis Under Reduced Pressure; Two‐Step, One‐Pot Amide Synthesis Using an Immobilised Transaminase/Lipase Cascade in Combination With By‐Product Removal

open access: yesChemBioChem, Volume 27, Issue 6, 27 March 2026.
The application of biocatalytic cascades for organic synthesis can be encouraged through the use of easy‐to‐handle, immobilised enzymes and common laboratory equipment. We present a sequential biocatalytic cascade reaction that couples a transaminase (ATA) with a lipase, and achieves high conversion and enantioselectivity through by‐product removal ...

Dynamic Covalent Polymeric Foams: En Route to a Sustainable Lightness

open access: yesChemSusChem, Volume 19, Issue 5, 13 March 2026.
Dynamic covalent polymer foams (DCPFs) combine lightweight cellular structures with adaptive polymer networks, enabling self‐healing, reprocessability, and recyclability. By integrating reversible covalent bonds into foam architectures, these materials open new pathways toward sustainable porous polymers within a circular materials economy.
