Tobacco chemistry. 27. The structures of four stereoisomeric 8, 12x1-epoxylabd-14-en-13xl-ols isolated from Greek Nicotiana tabacum L.
The structures of four stereoisomeric 8,12x1-expoxylabd-14-en-13x1-ols** obtained from Greek tobacco were determinedby spectroscopic means and by conversion to 12-norambreinolide. Plausible routes for the formation of the new labdanols and related tobacco constituents from a common precursor, abienol, are discussed.
