Butterfly-Shaped Dibenz[a,j]anthracenes: Synthesis and Photophysical Properties
, 2023 A strategy for the synthesis of dibenz[a,j]anthracenes (DBAs) from cyclohexa-2,5-diene-1-carboxylic acids is presented. Our approach involves sequential C–H olefination, cycloaddition, and decarboxylative aromatization. In the key step for DBA skeleton

Sterisch überfrachtete Alken‐Photo‐Redox‐Schalter auf Basis von Chinolinium/Carben Bausteinen
Angewandte Chemie, EarlyView.Eine modulare Synthese einer neuen Klasse von Photo‐ und Redox‐Schaltern wird beschrieben, die auf der Kombination von Chinoliniumsalzen und Carbenen basiert. Das photochemische Schalten ermöglicht einen selektiven Wechsel zwischen gefalteten E/Z‐Isomeren, während das elektrochemische Schalten den Wechsel zwischen neutralen, radikalkationischen und ...

Synthesis of Pentacyclic 13-Azadibenzo[a,de]anthracenes via Anionic Cascade Ring Closure
, 2016 Bromine−lithium exchange using tert-butyllithium at −78 °C initiates a cascade process whereby either xanthone derivatives or pentacyclic 13-azadibenzo[a,de]anthracenes are produced in high yields.

Toward Chromoselective Transformations in Biological Systems: Perspectives and Challenges
Angewandte Chemie International Edition, EarlyView.Controlling biological systems with small‐molecule chromophores has evolved into a powerful strategy and is applied from chemical biology to medicine. However, the complexity of in vivo systems cannot be matched by a single wavelength of light. Developing methods to combine and individually control multiple chromophores is crucial.
