Abstract
(+)-Juvabione (I) and two new analogs (III and IV) were isolated, together with trans-4-hydroxycinnamic acid (XIII) and vanillin (XIV), from the wood of Abies sachalinensis MAST. (Pinaceae). The structures of III and IV were established to be cis-4-[3 (S)-hydroxy-l (R), 5-dimethylhexyl] cyclohexane-l-carboxylic acid and trans-4-[3 (S)-hydroxy-l (R), 5-dimethylhexyl] cyclohexane-l-carboxylic acid, respectively, on the basis of chemical and spectral evidence.
