Die Flexibilität von Tetra(N‐Heterozyklisches Carben)‐Liganden kontrolliert die Nuklearität und Geometrie von polynuklearen MI‒NHC‐Strukturen

Angewandte Chemie, EarlyView.
Tetracarben‐Liganden aus zwei Di(phenylimidazol‐2‐yliden)amin‐Gruppen die über eine Anthracen‐Brücke verbunden sind zeigen eine behinderte Rotation der CPhenyl−N−CPhenyl‐Ebene relativ zur Anthracen‐Ebene wenn die N(Ph−NHC)2‐Gruppen direkt an Anthracen gebunden sind.

Structural Insight Into a Human H Ferritin@Gold‐Monocarbene Adduct: Aurophilicity Revealed in a Biological Context

Angewandte Chemie, EarlyView.
Human H ferritin (HuHf) is a nanocarrier for anticancer metal drugs. By cryo‐EM, a 1.51 Å structure of its adduct with Au(NHC)Cl was solved, showing a novel tetranuclear gold(I) cluster bound to Cys90 and Cys102. Short inter‐metal distances indicate aurophilic interactions.

Eine spannende Reise: Wolfram(VI)‐ und Wolfram(V)‐Fluoride treffen auf N‐Heterocyclische Carbene und cyclische (Alkyl)(Amino)carbene

Angewandte Chemie, EarlyView.
Die ersten Wolfram(VI)‐Fluorido‐Komplexe mit N‐heterocyclischen Carbenen (NHCs) und cyclischen (Alkyl)(Amino)carbenen (cAACs) als Liganden wurden synthetisiert und charakterisiert. Die Reduktion der siebenfach koordinierten Komplexe führte zu seltenen, Lewis‐Basen‐stabilisierten oktaedrischen Wolfram(V)‐Fluorido‐Komplexen, einem dinuklearen, Fluorido ...

An Artificial Metal‐Free Peroxidase Designed Using a Ferritin Cage for Bioinspired Catalysis

Angewandte Chemie, EarlyView.
Designing artificial enzymes remains challenging due to the need for precise active site control. Here, we present a simple strategy to create metal‐free artificial enzymes by engineering Histidine clusters inside a ferritin cage. The resulting catalyst mimics peroxidase activity, and its stable cage structure offers new insights into supramolecular ...

Structural Basis of Sequential Enantioselective Epoxidation by a Flavin‐Dependent Monooxygenase in Lasalocid A Biosynthesis

Angewandte Chemie, EarlyView.
Lsd18 is a flavin‐dependent monooxygenase from Streptomyces lasalocidi that performs two enantioselective epoxidations during lasalocid A biosynthesis. X‐ray crystal structures of Lsd18 bound to a substrate and product analogue illuminate how this enzyme performs multiple epoxidations on the same substrate molecule and how it controls stereoselectivity.
