Structures and Conformations of (-)-Isobicyclogermacrenal and (-)-Lepidozenal, Two Key Sesquiterpenoids of the cis- and trans-10,3-Bicyclic Ring Systems, from the Liverwort Lepidozia vitrea: X-Ray Crystal Structure Analysis of the Hydroxy Derivative of (-)-Isobicyclogermacrenal

The structures and absolute configurations of the two sesquiterpene aldehydes, (-)-isobicyclogermacrenal (1) and (-)-lepidozenal (2), which were isolated from the liverwort Lepidozia vitrea, have been determined on the basis of chemical and spectroscopic evidence to be (6R,7S)-6,11-cyclogermacra-1(10)E,4E-dien-14-al and (6R,7R)-lepidoza-1(10)E,4E-dien-14-al, cosisting of the cis- and trans-10,3-bicyclic ring systems.The structure of the former (1) has been confirmed by a single-crystal X-ray analysis of its hydroxy derivative (7).The molecular conformations, biogenetical features, and biological activity are also described.

(-)-LEPIDOZENAL, A SESQUITERPENOID WITH A NOVEL TRANS-FUSED BICYCLOUNDECANE SYSTEM FROM THE LIVERWORT LEPIDOZIA VITREA

A sesquiterpene aldehyde, (-)-lepidozenal, having a novel trans-fused bicycloundecane carbon skeleton has been isolated from the liverwort Lepidozia vitrea, and its structure and absolute configuration have been shown to be (6S,7R)-lepidoza-1(10)E,4E-dien-14-al, on the basis of the chemical and spectral evidence.
