“…214 The essential oil of the liverwort Plagiochila asplenioides contained one oxygenated sesquiterpene (+)-muurolan-4,7-peroxide 379. 215 The NMR data of the sesquiterpene peroxide 380 216 are also reported for the first time in the same paper. The aerial parts of the invasive plant Eupatorium adenophorum contain the new sesquiterpene 381.…”

“…From a synthetic standpoint, the installation of the endoperoxide moiety presents a significant challenge due to its susceptibility to reduction and for this reason, is ideally introduced late-stage in target-oriented synthesis. Additionally, many endoperoxide natural products possess architecturally complex frameworks (e.g., artemisinin, yingzhaosu A, muurolan-4,7-peroxide) [5] that pose significant synthetic challenges.…”

SummaryTriarylpyrylium salts were employed as single electron photooxidants to catalyze a cyclization–endoperoxidation cascade of dienes. The transformation is presumed to proceed via the intermediacy of diene cation radicals. The nature of the diene component was investigated in this context to determine the structural requirements necessary for successful reactivity. Several unique endoperoxide structures were synthesized in yields up to 79%.

“…The essential oil from the German liverwort P. asplenioides showed the presence of 2,3-seco-aromadendrane-type sesquiterpenoids. Plagiochilines W (16) and X (17) were detected among other components of this essential oil [46]. This liverwort was classified in chemotype I of Plagiochila species [6].…”

Studies concerning chemical profiling of the volatiles present in the solvent extracts from liverworts help to determine inter-and intraspecific relationships in this plant group. Due to the fact that the liverworts are morphologically very small and it is difficult to collect their sufficient amounts, there are still a few data concerning the chemistry of essential oils. The available data indicate however, that the components present in the essential oils can be used in chemosystematic studies of these spore-forming plants. Compounds occurring in the essential oils constitute a powerful tool for studying chemical differences between or within liverwort species for which the characteristic components are mono-and sesquiterpenoids. Good results were obtained for the liverworts species from the genera Asterella,
