A NOR-SECO-AROMADENDRANE FROM THE LIVERWORT MYLIA TAYLORII

A novel nor-seco-aromadendrane, 2-nor-1,3-epoxy-1,10-seco-aromadendra-1(5),3-dien-10-one, was obtained from Mylia taylorii.It was identified by spectroscopic methods and chemical correlation with a known compound. - Keywords: Mylia taylorii; Hepaticae; liverworts; sesquiterpenoids; nor-seco-aromadendrane; 2-nor-1,3-epoxy-1,10-seco-aromadendra-1(5),3-dien-10-one.

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.
