Convergent Total Synthesis of 16β‐Hydroxylpseudobufarenogin

Angewandte Chemie, EarlyView.
We present a novel convergent strategy that integrates Pd/Ag‐promoted Suzuki–Miyaura coupling with Ir‐catalyzed radical‐relay cyclization, enabling the first total synthesis of 16β‐hydroxylpseudobufarenogin. This approach is broadly applicable to the total synthesis of various oxygenated bufadienolides by simply modifying the fragment structures ...

Bent N‐Heterocyclic Allenes From a Well‐Defined Titanium Vinylidene Complex

Angewandte Chemie, EarlyView.
The syntheses and the structures of N‐heterocyclic allenes are reported. Allenes bearing fluorenylidene capping groups show markedly bent C═C═C units, a carbene‐like reactivity, and they can act as potent C‐donor ligands for metal complexes. ABSTRACT Allenes typically display a linear geometry. A notable exception occurs in allenes bearing two electron‐

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‐
