Thiophenderivate als vielseitige Vorstufen für die Synthese von (Hetero)aromaten und Naturstoffen
Angewandte Chemie, EarlyView.Verborgen, aber leistungsstark: Thiophene und ihre gesättigten Analoga haben sich als vielseitige C4‐Bausteine erwiesen, die sich effektiv in der Naturstoffsynthese sowie beim Aufbau funktionalisierter (Hetero)aromaten einsetzen lassen. Dieser Minireview soll einen Überblick über Strategien zur Anwendung dieser schwefelhaltigen heterozyklischen ...

Alkinyltriazene in photochemischen metallfreien Doyle‐Kirmse‐Umlagerungen
Angewandte Chemie, EarlyView.Es wird eine metall‐ und additivfreie photokatalytische Doyle‐Kirmse‐Reaktion von Alkinyltriazenen beschrieben, die über Cyancarbenzwischenstufen verläuft. Diese Strategie ermöglicht den effizienten Aufbau hochsubstituierter asymmetrischer Kohlenstoffzentren mit breitem Substratspektrum und liefert synthetisch wertvolle Nitrile.

Angewandte Chemie, Volume 138, Issue 4, 22 January 2026.Diazirines are three‐membered, nitrogen‐containing heterocycles that decompose under light or heat to generate carbenes. For the past two decades, they have served mainly as minimally invasive tags in photoaffinity labeling (PAL). More recently, their value as versatile carbene precursors has been recognized.

Mechanochemical Synthesis of X‐Vinylbenziodoxol(on)es and One‐Pot Conversion to Complex Alkenes**
Angewandte Chemie, Volume 138, Issue 4, 22 January 2026.The synthesis of a wide range of complex 1,2‐di(heteroatom)‐substituted (Z)‐alkenes is achieved through a mechanochemical one‐pot reaction of ethynylbenziodoxol(on)es (EBX/EBO) with a variety of heteroatom nucleophiles. The mechanochemical activation enables synthesis of a range of novel vinylbenziodoxol(on)es (VBX/VBO) whose synthesis is inefficient ...
