โœฆ Synopsis

From the ether extract of the liverwort Odontoschisma denudatum, three novel ent-bibsaneand a novel dolabollane-type diterpenoids have been isolated. Their absolute structures were determined by a combination of 2D-NMR, X-ray crystallographic analysis, modified Mosher method, and chemical degradation.

From the ether extract of the liverwort Odontoschisma denudatum, two novel diterpenoids, neodenudatenones A and B, having a new carbon skeleton named neodenudatenone-type have been isolated. Their absolute structures were determined by a combination of high resolution 2D-NMR and CDspectra, and cbemi
