Spirocyclische Cyclopropane wurden durch Umsetzung von Ketosulfon- und Cyanoaceton-Dianionen hergestellt und durch Behandlung mit Tetraalkylammoniumhalogeniden in funktionaliserte Arene überführt. Durch Cyclisierung des Dianions von Aceton und eines 3-Oxophosphonates konnten regioisomere Spirocyclopropane hergestellt und durch anschließende Umsetzung mit Tetraalkylammoniumhalogeniden in funktionaliserte Arene überführt werden. Es wurden Beiträge zur Synthese von Diarylethern, Biarylen und 1-Azaxanthonen geliefert. Weiterhin wurden Ergebnisse auf dem Gebiet der regioselektiven Synthese von Thiophenen durch Suzuki-Reaktionen von Tetrabromthiophen geliefert. Schließlich wurden neue Naturstoffe isoliert und charakterisiert.Spirocyclic cyclopr...
