Abstract
- 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.
