Angewandte Chemie, Volume 138, Issue 25, 15 June 2026.Die geminale Difunktionalisierung leicht verfügbarer Bausteine ermöglicht einen schnellen Zugang zu molekularer Komplexität. Diese Arbeit stellt eine Strategie vor, um zwei unterschiedliche funktionelle Gruppen an einem Carbonylkohlenstoff zu installieren, indem dieser in eine Donor–Donor‐Diazo‐Verbindung überführt wird. Die Methode ist sowohl im Batch‐

Angewandte Chemie International Edition, Volume 65, Issue 25, 15 June 2026.Geminal difunctionalization of readily available building blocks provides rapid access to molecular complexity. This work introduces a strategy for installing two distinct functional groups on a carbonyl carbon by transforming it into a donor–donor diazo compound, enabling both batch and flow applications with broad solvent compatibility.

The Wonders of Vanilla: Celebrating the 150th Anniversary of Synthetic Vanillin
ChemFoodChem, Volume 2, Issue 2, June 2026.The year 2024 marked the 150th anniversary of the first commercial production of vanillin, one of the world's most cherished flavor ingredients. This review traces vanilla's history from Mesoamerica to modern production methods, examines its composition, the discovery of vanillin and Haarmann's early synthesis compared to modern methods, and highlights

New Phytologist, Volume 250, Issue 5, Page 3230-3246, June 2026.Summary Carotenoids and apocarotenoids are widespread specialized metabolites, yet animals, including sponges, lack the ability to synthesize carotenoids de novo and must obtain them from dietary or microbial sources. The roles of carotenoid cleavage dioxygenases (CCDs) in marine animals remain largely unexplored. A CCD from the marine sponge Suberites

Advanced Synthesis &Catalysis, Volume 368, Issue 9, 5 May 2026.Fungal unspecific peroxygenases (UPOs) are promiscuous heme‐containing enzymes that selectively oxyfuntionalize C‐H bonds. Structural and enzymatic reaction studies of an evolved UPO mutant from Candolleomyces (Psathyrella) aberdarensis (PabUPO‐I) reveal how the heme channel architecture dictates the regioselectivity towards alkanes, fatty acids and ...
