Abstract : Thunbergol is a monocyclic diterpene alcohol which occurs in the oleoresin of Douglas fir, Pseudotsuga menziesii (Mirb.) Franco. Spectroscopic studies and dehydration to thunbergene (cembrene) established the structure (1-isopropyl-4,8,12-trimethyl-2,7,11-cycloteradecatriene-4-o1) of thunbergol which is thus a new member of the diterpene series containing a fourteen-membered ring. The possible relationships between thunbergol and cembrol previously isolated from Pinus sibirica R. Mayr. are discussed. (Author)
