    An epoxy-trinoreudesmane sesquiterpene from the liverwort Lophocolea bidentata
    摘要:
    A new epoxy-trinoreudesmane sesquiterpene, (+)-(4S,4aS,5R,8aS)-trans-4,8a-dimethyl-4a,5-epoxy-decalin, 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.

    presented from the readily available optically active Wieland−Miescher ketone. This novel synthesis of this sesquiterpene lactone features the following as key stereoselective transformations: (i) the ring contraction reaction of a octalone mediated by thallium(III) nitrate (TTN); (ii) a hydrogenation to create the cis-fused junction; and (iii) the formation of the C7 quaternary center through an enolate intermediate

    Cultures of the myxobacterium Chondromyces crocatus on agar plates were analysed by closed-loop-stripping analysis or solid phase micro extraction. The odour profiles consist mainly of pyrazines, sesquiterpenoids and some aromatic compounds, summing up to more than 50 components. Several new pyrazines as 2-(1-hydroxy-1-methylethyl)-3-methoxypyrazine (9), 2-(1-hydroxy-1-methylpropyl)-3-methoxypyrazine

    Synthetic routes to geosmin and its enantiomer are well established, but the enantioselective synthesis of stereoisomers of geosmin is unknown. Here a stereoselective synthesis of all stereoisomers of geosmin is reported, yielding all compounds in high enantiomeric purity. Furthermore, the stereoselective synthesis of a geosmin derivative isolated from a mangrove associated streptomycete was performed,
