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.

Design, Synthesis, and Structural Evolution of Pseudo‐Natural Product IDO1 Inhibitors and Degraders

open access: yesAngewandte Chemie, Volume 138, Issue 3, 16 January 2026.
The combination of bicyclic monoterpene‐ and pyrrolidine‐alkaloid fragments yields novel pseudo‐natural products. Biological characterization revealed that these iDegs are inhibitors and degraders of indoleamine‐2,3‐dioxygenase. Abstract Terpenoid alkaloids are derived from the fusion of structurally diverse terpenoid‐ and alkaloid moieties.
