Schwefel‐gesteuerter Aufbau von Vinylcyclopropanen ausgehend von 1,3‐Dienen

Angewandte Chemie, EarlyView.
Schwefel übernimmt die Kontrolle: Ein Thioether wirkt als molekularer Dirigent, der die Carbenaddition an 1,3‐Diene mit außergewöhnlicher Regio‐ und Diastereokontrolle lenkt. Dabei werden schwefelhaltige Vinylcyclopropane (S‐VCPs) erhalten, die mittels herkömmlicher Methoden nur schwer zugänglich sind.

Strategies Toward Accessing Enantioenriched (Hetero)Benzo‐Fused 5‐ and 6‐ Membered Rings via Intermolecular Carbometalation

Angewandte Chemie, EarlyView.
The use of transition‐metal catalysts and design of chiral ligands have allowed chemists to access highly functionalized benzofused 5‐ and 6‐ membered rings in high yield and enantioselectivity. A common strategy used relies on an intermolecular carbometalation across alkynes and olefins, usually followed by a subsequent intramolecular carbometalation.

Alcohol‐Directed Carboamination of Conjugated Enynes

Angewandte Chemie, EarlyView.
The first general three‐component intermolecular Pd‐catalyzed carboamination of conjugated enynes enables the coupling of anilines and aryl triflates to produce functionalized allenic amines, utilizing a native alcohol directing group to control regioselectivity.

Geminale Difunktionalisierung von Ketonen durch C–S Bindungs‐insertion photogenerierter Donor–Donor Diazoverbindungen

Angewandte Chemie, EarlyView.
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‐

Potassium‐Ligand Cooperation Facilitated Chemical Bond Activation and Catalytic Hydrogenation

Angewandte Chemie, EarlyView.
A new strategy for alkali metal‐mediated catalysis based on metal–ligand cooperation (MLC) is presented. Potassium pincer complexes exhibit remarkable reactivity toward a range of molecules via an unprecedented potassium–ligand cooperative mechanism. This reactivity enables potassium‐catalyzed hydrogenation, providing efficient reduction of ketones and
