Abstract
From the ether extract of the liverwort Odontoschisma denudatum, two n ovel diterpenoids, neodenudatenones A and B, having a new carbon skele ton named neodenudatenone-type have been isolated. Their absolute stru ctures were determined by a combination of high resolution 2D-NMR and CD spectra, and chemical degradation. (C) 1998 Elsevier Science Ltd. A ll rights reserved.
