Article abstract of DOI:10.1016/0031-9422(95)00355-B

A new epoxy-trinoreudesmane sesquiterpene, (+)-(4S,4aS,5R,8aS)-trans-4,8a-dimethyl-4a,5-epoxydecalin, was isolated from the liverwort Lophocolea bidentata, collected in northern Germany.The structure of this compound was elucidated by means of spectroscopic methods and by independent synthesis.The configuration was proved by enantioselective gas chromatography.The previously described olefinic precursor was also identified as a constituent. - Key words: Lophocolea bidentata; L. heterophylla; liverworts; sesquiterpenes; epoxy-trinoreudesmane; 4,8a-dimethyl-1,2,3,4,6,7,8,8a-octalin.
