Regioselective Hydration of Terpenes with Cofactor‐Independent Carotenoid 1,2‐Hydratase

Angewandte Chemie, EarlyView.
This study reveals a highly regioselective and cofactor‐independent enzymatic approach to terpene and terpenoid hydration using a carotenoid 1,2‐hydratase from Rubrivivax gelatinosus. Beyond detailing reaction optimization strategies, an extensive substrate scope, and scale‐up potential, it explores mutagenesis and structural modeling to identify key ...

Totalsynthese und Strukturkorrektur von (−)‐Sodagnitin E

Angewandte Chemie, EarlyView.
Das Malabarican‐Triterpen Sodagnitin E ist ein in verschiedenen Pilzen vorkommendes Chromogen. Die vorliegende Arbeit stellt sowohl die erste Totalsynthese von (−)‐Sodagnitin E als auch die erste Synthese eines Malabaricans überhaupt dar. Die konvergente Synthese basiert auf der Verknüpfung zweier enantioselektiv hergestellter Fragmente mittels ...

Hochgradig enantioselektive Organokatalyse mit zweizähnigen Halogenbrückendonoren

Angewandte Chemie, Volume 137, Issue 30, July 21, 2025.
In einer Mukaiyama‐Aldol‐Modellreaktion mit allgemeinen Substraten wurden hohe Enantioselektivitäten mit einem modifizierbaren, bidentaten Iod(I)‐basierten Halogenbrücken‐Organokatalysator erreicht. Die entscheidende Rolle der Halogenbrücken wurde durch das schlechte Abschneiden des entsprechenden Wasserstoffbrückendonors und durch DFT‐Berechnungen ...

On‐Surface Synthesis and Characterization of Cumulene‐Linked Stone‐Wales Polymers

Angewandte Chemie, EarlyView.
On‐surface synthesis of one‐dimensional polymers featuring Stone‐Wales defects and cumulene linkages is demonstrated via thermally and light‐induced reactions on Au(111). STM, nc‐AFM, and Raman spectroscopy, complemented by theory calculations, reveal their chemical structure with a non‐planar geometry, and a distinct electronic bandgap of 1.8 eV ...

Chiral Selenium‐Integrated Multi‐Resonant Thermally Activated Delayed Fluorescent Emitters Showing Improved Reverse Intersystem Crossing Rate

Angewandte Chemie, EarlyView.
The selenium‐based tBuCz‐DiKTaSe emitter containing a twisted ortho‐disposed tert‐butylcarbazole shows high ΦPL, suppressed ACQ, fast kRISC and is chiral. The OLEDs show high EQEmax and alleviated efficiency roll‐off compared to devices with carbonyl‐based MR‐TADF emitters.
