Thiophenderivate als vielseitige Vorstufen für die Synthese von (Hetero)aromaten und Naturstoffen

Angewandte Chemie, Volume 138, Issue 5, 28 January 2026.
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 ...
