Nitrogenous Sesquiterpenoids from the South China Sea Nudibranch Hexabranchus sanguineus and Its Possible Sponge-Prey Acanthella cavernosa:Chiral Separation,Stereochemistry and Chemical Ecology
文献摘要：
A detailed chemical investigation of the South China Sea nudibranch Hexabranchus sanguineus,as well as its possible sponge-prey Acanthella cavernosa,led to the isolation of fifteen new nitrogenous sesquiterpenoids,namely ximaocavernosins A-O,including seven cadinanes (1-7),seven spiroaxanes (12-18) and one aromadendrane (19),together with thirteen known related compounds (8-11 and 20-28).Compounds (±)-1-9 (except for 4 and 6) were further separated by chiral-phase HPLC to their corresponding unequal enantiomers,respectively.Their structures and absolute configurations were determined by a combination of extensive spectroscopic data analysis,quantum mechanical nuclear magnetic resonance (QM-NMR) methods,Mosher's method,X-ray diffraction analysis and/or time-dependent density functional theory/electronic circular dichroism (TDDFT-ECD) calculation.The commonly existed ni-trogenous sesquiterpenoids in these two animals are suggested to be chemical markers for their prey-predator relationship.
