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

European Journal of Organic Chemistry, EarlyView.
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.

Total Synthesis of the Cyanobacterial Alkaloid Nostodione A

European Journal of Organic Chemistry, EarlyView.
The total synthesis of the alkaloid nostodione A is successfully achieved utilizing 3,4‐dihydrocyclopenta[b]indole‐1,2‐dione as a key intermediate. The sensitive benzylidene moiety is introduced via a Knoevenagel condensation with p‐hydroxybenzaldehyde.

Electrochemical Intramolecular Aminobromination of Alkenes

European Journal of Organic Chemistry, EarlyView.
A versatile electrochemical method for the intramolecular aminobromination of alkenes has been developed. The method provides access to five‐, six‐, and seven‐membered heterocycles by exploiting tetrabutylammonium bromide as an electrolyte and bromine source.
