Description / Table of Contents:
Condensed Ring Systems, II1). Bilobalid A, a New Sesquiterpene Obtained from the Leaves of Ginkgo biloba L. and Containing a Tertiary Butyl GroupA new sesquiterpene C15H18O8, Bilobalid A, has been isolated from fresh leaves of the Ginkgo tree. It is closely related, both in structure and properties, to the ginkgolides (diterpenes, C20H24O9-11), whose structure has been elucidated in the last few years. Like the latter, its molecule contains a tertiary butyl group, which hitherto has not been detected in other natural products.
Notes:
Aus frischen Blättern des Ginkgo-Baumes wird ein neues Sesquiterpen C15H18O8, Bilobalid A, isoliert, welches in seiner Konstitution und seinen Eigenschaften den in den letzten Jahren aufgeklärten Ginkgoliden (Diterpene, C20H24O9-11) nahesteht. Es besitzt wie diese eine tert.-Butyl-Gruppe, die in anderen Naturstoffen bisher nicht nachgewiesen wurde.
