Abstract

Terpene stellen die größte und strukturell vielfältigste Gruppe von Naturstoffen dar. Sesquiterpene sind für ihren charakteristischen Geruch und Geschmack bekannt und werden in großem Umfang in der Parfüm- und Lebensmittelindustrie verwendet. Sie bestehen aus sich wiederholenden Isopreneinheiten, die durch Kondensation der biosynthetischen Bausteine Isopentenyl- und Di- methylallylpyrophosphat aufgebaut werden. Die einfachen linearen Vorstufen werden dann durch Terpenzyklasen in verschiedene polyzyklische Produkte umgewandelt. In diesen Kaskadenreaktio-nen durchlaufen die Vorstufen mehrfache Veränderungen in der Konstitution, Hybridisierung und Stereochemie. Diese komplexe Kaskade ist für jede Zyklase einzigartig und führt zu einer großen Vielfalt an möglichen Strukturen. In dieser Arbeit sollte ein aus Biotransformationsuntersuchungen eines nicht natürlichen FPP-Deri-vats mit der STC Bot2 gewonnenen Trizyklus synthetisiert werden, um seine Stereochemie zu veri-fizieren und weitere Eigenschaften durch Derivatisierung zu untersuchen. Zum anderen wurden Far-nesylderivate synthetisiert, die Oxidationen an den terminalen Methylgruppen tragen. Damit sind Oxidationen an Positionen gemeint, die später üblicherweise durch enzymatische Folgereaktionen oxidiert werden. Diese Substrate wurden mit Hilfe verschiedener chemischer Verfahren um Doppel- und Dreifachbindungen herum synthetisiert, um die erforderliche Regioselektivität zu gewährleisten. Neue Produkte aus Biotransformationsexperimenten wurden isoliert und ihre Strukturen wurden auf-geklärt.
