Tetrazine Functionalized Graphene Enables Capture of Ultra‐Low Concentrations of Biomacromolecules

Small, EarlyView.
A novel method for covalent modification of monolayer graphene utilizing tetrazine containing diazonium salt is demonstrated. The modified graphene bearing tetrazine moieties undergoes inverse electron demand Diels‐Alder reactions with trans‐cyclooctene‐linked molecules, enabling bioorthogonal attachment of nanobodies that selectively capture EGFP ...

Eugenol‐Derived Sustainable Cyclic Carbonates and Polythiocarbonates from CO2 and COS as Efficient Hybrid Catalysts for Suzuki–Miyaura Cross‐Coupling Reactions

Advanced Sustainable Systems, Volume 10, Issue 4, April 2026.
A bio‐based palladium‐ligated polymer catalyst was achieved through COS/eugenol‐epoxide copolymerization and post‐polymerization functionalisation using click chemistry. The resulting hybrid catalyst efficiently catalyses Suzuki cross‐coupling reactions at low catalyst loadings with excellent recyclability.

Two‐Step Access to 4‐Aryl‐5‐Heteroarylpyrazoles via Palladium‐Catalyzed Sequential Transformations Using Palladium 1,4‐Migration Tool

Asian Journal of Organic Chemistry, Volume 15, Issue 4, April 2026.
Access to pyrazoles arylated at C4 and C5 positions remains challenging due to their similar reactivity under Pd‐catalyzed C–H activation conditions. Herein, we report on the synthesis of 4‐aryl‐5‐heteroarylpyrazoles involving Suzuki‐coupling, followed by Pd‐catalyzed C–H heteroarylation.

Site‐Selective Oxidative Dimerization of Oxaphenalenone Scaffolds: Total Synthesis of (±)‐Bacillosporin C

ChemistryEurope, Volume 4, Issue 4, April 2026.
An effective electrochemical synthetic route to bacillosporin C, a dimeric oxaphenalenone of the duclauxin family, is disclosed. The key transformation is a site‐selective oxidative homocoupling of the oxaphenalenone monomer SF226, achieved under redox‐mediator‐free conditions.

Modular Access to Bridgehead Heterocycle‐Substituted Bicyclo[1.1.0]butanes via Late‐Stage Functionalization of Alkynylbicyclo[1.1.0]butanes

Chemistry–Methods, Volume 6, Issue 4, April 2026.
A modular late‐stage manifold exploits the embedded alkyne of alkynylbicyclo[1.1.0]butanes (ABCBs) to deliver triazole‐, isoxazole‐, free‐NH‐pyrrole, free‐NH‐pyrazole, or silacyclohexene‐decorated BCBs in a single operation. Strain‐release transformations of bicyclo[1.1.0]butanes are powerful methods for constructing four‐membered rings and bicyclo[n.1.

A Convenient One‐Pot CuI‐Catalyzed Procedure for the Synthesis of S‐(N‐Heteroaryl) Thiocarboxylates From N‐Heteroaryl Bromides and Thiobenzoic Acid

ChemistryOpen, Volume 15, Issue 4, April 2026.
A one‐pot two‐step CuI‐catalyzed procedure for the synthesis of S‐(N‐heteroaryl) thiocarboxylates from N‐heteroaryl bromides and thiobenzoic acid was developed, which is highlighted by shorter reaction time, a smaller amount of iodide source and scalability.

Synthesis of Heterocyclic Scaffolds from Nitrobenzyl Alcohols Using Reduction‐Generated Azaquinone Methides and Cyclization

European Journal of Organic Chemistry, Volume 29, Issue 12, 23 March 2026.
Intramolecular cyclization to quench an in situ reduction‐generated azaquinone methide is a strategy that could be used for late‐stage heterocycle synthesis. Herein, synthetically accessible 4‐nitrobenzyl alcohols with a nucleophilic handle adjacent to the benzyl alcohol group are reduced under mild conditions to afford six‐ and seven‐membered ...

Development of a Self‐Adjuvanting Influenza Peptide–Glycolipid Conjugate Inducing CD8+ T‐Cell Immunity

ChemBioChem, Volume 27, Issue 5, 13 March 2026.
The glycolipid‐peptide antigen complexes for self‐adjuvanting conjugates were successfully synthesized, and, with the HLA‐transgenic mice, the antigen‐specific CD8+ T cell expansion was exhibited. The results provide useful insights for the design and synthesis of vaccine conjugates using glycolipid antigen as an adjuvant.
