✦ Synopsis
A straightforward route to functionalized bicyclo[6.3.0]undecane derivatives, which can be used in terpene synthesis, is described. The trans configuration of the acetall2 is established by an X-ray structural analysis.

). -Ein einfaeher Zugang zu Bieyelo[6.3.0]undeean-Derivaten Es wird ein einfacher Weg zu funktionalisierten Bicyclo[6.3.0]undecan-Derivaten beschrieben, die als Zwischenprodukte bei Terpensynthesen genutzt werden konnen. Die trans- Konfiguration des Acetals 12 wird durch eine Rontgenstrukturanalyse bewiesen. *) All compounds prepared are racemates. For the sake of simplicity only one relative configuration is given in the Schemes.
