Bis‐Furans: A Sustainable Source of Diverse Molecular Architectures

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 10, 9 March 2026.
A concise synthetic route to diverse acyclic and heterocyclic compounds has been developed by combining hetero‐Diels–Alder reactions, DBU‐promoted ring openings, and Lewis base‐catalyzed annulations. Nitrosoalkenes reacted with furan derivatives to form 4a,7a‐dihydro‐4H‐furo[2,3‐e][1,2]oxazines, which underwent DBU‐promoted rearrangements to 6H‐1,2 ...

Glycerol and Q-Tubes: Green Catalyst and Technique for Synthesis of Polyfunctionally Substituted Heteroaromatics and Anilines

open access: yesMolecules, 2019
The role of glycerol as a green bio-based solvent, reactant, and/or a catalyst in the synthesis of novel heterocycles, under pressure, is studied. Synthesis of novel quinolines in good yields using a new modified Skraup synthesis, utilizing glycerol and ...

The NLRP3 Inflammasome: Mechanisms of Activation, Regulation, and Therapeutic Opportunities

open access: yesMedComm, Volume 7, Issue 3, March 2026.
Diverse diseases converge on NLRP3. We depict a discovery‐to‐clinic track: high‐throughput/phenotypic screens, structure‐guided design, and modality innovation (allosteric inhibitors, interface blockers, degraders) deliver third‐generation, disease‐tailored NLRP3 control.

Carbon Nitride Thin‐Film Planar Heterojunctions for Photoelectrocatalytic C–N Coupling

open access: yesSmall Structures, Volume 7, Issue 3, March 2026.
Carbon nitride thin films have attracted increasing attention as active materials for energy conversion. Herein, it is shown how the presence of a conductive interlayer can substantially improve performance and photoelectrode stability in the photoelectrocatalytic oxidation of organic molecules and how the conductive interlayer influences product ...

Photoinduced, Chemoselective γ‐Alkylation of 2‐Silyloxyfurans With α‐Bromoketones: A Rapid Entry to Chiral ε‐Keto‐γ‐Butenolides

open access: yesChemistry – A European Journal, Volume 32, Issue 5, 2 February 2026.
A photoinduced, regio‐ and chemoselective γ‐alkylation of 2‐silyloxyfurans with a‐bromoketones was achieved by exploiting a photoredox catalytic process promoted by blue light. This approach provides practical and efficient access to chiral, ε‐ketobutenolides, in one step and high yields.

Microdroplet Stabilization Enabled Direct Mass Spectrometric Identification of Electrogenerated Transient Carbocation Intermediates

open access: yesAdvanced Science, Volume 13, Issue 9, 13 February 2026.
The in situ mass spectrometric identification of the electrogenerated benzylic and phenylic carbocations, whose half‐lives in bulk solutions are on the nanosecond scale, is achieved by taking advantage of the unique stabilization effect of the electrosprayed microdroplets.

Expanding Horizons in Phage Therapy: Addressing Antibiotic Resistance in Aquaculture

open access: yesAquaculture, Fish and Fisheries, Volume 6, Issue 1, February 2026.
ABSTRACT Aquaculture has emerged as a cornerstone of global food security, yet its rapid intensification has precipitated widespread bacterial disease outbreaks and escalating antimicrobial resistance (AMR). This review critically examines the limitations of conventional antibiotic use in aquaculture, highlighting regulatory inconsistencies ...

π‐Expanded Nitrogen‐Cation (N+)‐Doped Polycyclic Aromatic Hydrocarbons: A Review of Intramolecular Cyclization Routes to Benzo[c]Quinolizinium, Triazinium, Pyridoquinazolinium, and Pyridoquinoxalinium Frameworks

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 4, January 26, 2026.
This review surveys recent progress in the synthesis of extended aromatic quinolizinium derivatives via intramolecular SNAr and oxidative 6π‐electrocyclization. Conventional thermal approaches are discussed alongside emerging, sustainable activation methods such as electrosynthesis and photochemical processes.

RNA‐Lebendzellmikroskopie via click‐funktionalisierter TriPPPro Nucleotid‐Reporter

open access: yesAngewandte Chemie, Volume 138, Issue 2, 9 January 2026.
Die intrazelluläre Zufuhr von trans‐Cycloocten und Bicyclo[6.1.0]nonin als sterisch anspruchsvolle Gruppen für die Diels–Alder‐Reaktion mit inversem Elektronenbedarf wurde durch die Triphosphat‐Prodrug‐Strategie (TriPPPro) erreicht. Nach der Hydrolyse innerhalb der Zelle werden die modifizierten Uridine und Cytidine metabolisch in die neu entstehende ...
