Tobacco Chemistry. 73. 4,6,8-Trihydroxy-11-Capnosene-2,10-dione, a Cembrane-Derived Bicyclic Diterpenoid from Tobacco.
摘要:
A new diterpenoid containing a rare carbobicyclic cembrane-derived skeleton, the capnosane skeleton, has been isolated from flowers of Greek tobacco. It has been identified as (1S*,3R*,4S*,6R*,7R*,8R*,11Z)-4,6,8-trihydroxy-11-capnosene-2,10-dione (1) by spectral methods and X-ray analysis of the corresponding benzoate (3). A full account of the X-ray work is given.
