In der vorliegenden Arbeit wird die erste Totalsynthese des marinen Naturstoffs Dolabelid B beschrieben. Das 22-gliedrige Makrolakton wurde 1995 von Yamada et al. aus dem japanischen Seehasen Dolabella auricularia isoliert und besitzt mit einer IC50 von 1.3 µg/mL eine vielversprechende zytotoxische Aktivität gegenüber der Krebszelllinie HeLa-S3. Die hoch konvergente Synthese basiert auf dem nachwachsenden Rohstoff Geranylacetat, aus dem zwei Fragmente des Naturstoffs aufgebaut wurden. Die Schlüsselreaktion zur Darstellung des C1-C18-Fragments war eine Linchpinkupplung zweier Epoxide, die über eine hydrolytische kinetische Racematspaltung und eine Titan-Salalen- katalytisierte, diastereoselektive Epoxidierung eines terminalen Alkens erhalten...
