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, 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.

Symmetrical Imidazo[1,5‐a]pyridine Dimers as Novel Organic Light Emitters: Bidirectional Synthesis and Photoluminescence Characterization

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Imidazo[1,5‐a]pyridine dimers are synthesized via a bidirectional strategy and characterized by single‐crystal X‐ray diffraction. The key substitution position for tuning optical properties is identified. Photophysical studies, supported by density functional theory calculations, show fluorescence in the 490–580 nm range, with the most planar system ...

Preparation and Structure of Meta‐Hydroxy‐Substituted Aryliodonium Salts: New Structural Type of Phenol‐Derived Hypervalent Iodine Compounds

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
The previously unknown meta‐hydroxy‐substituted aryliodonium salts were prepared by a two‐step one‐pot synthesis from 3‐acetoxy‐1‐[(diacetoxy)iodo]arenes and arylboronic acids. This procedure works well with halogen‐, methyl‐, methoxycarbonyl‐, or methoxy‐substituted arylboronic acids as well as naphthalenylboronic acids, phenanthren‐9‐ylboronic acid ...

Supra and subgingival application of antiseptics or antibiotics during periodontal therapy

open access: yesPeriodontology 2000, EarlyView., 2023
Abstract Periodontal diseases (gingivitis and periodontitis) are characterized by inflammatory processes which arise as a result of disruption of the balance in the oral ecosystem. According to the current S3 level clinical practice guidelines, therapy of patients with periodontitis involves a stepwise approach that includes the control of the patient ...
