GYMNOMITRANE SESQUITERPENOIDS FROM THE LIVERWORT MARSUPELLA EMARGINATA VAR. PATENS

Three new gymnomitrane sesquiterpenoids have been isolated from the liverwort Marsupella emarginata var. patens together with the known (-)-gymnomitrene and (-)-ar-curcumene.Their structures and absolute configurations have been determined on the basis of chemical and spectroscopic evidence as well as from the results of an X-ray analysis of a derivative.We also describe the ring expansion reaction of the gymnomitrane framework and the chemosystematics of the genus Marsupella.
