Abstract
A biogenetically unexpected diterpenoid, teubetonin, has been isolated from the aerial parts of Teucrium betonicum (Labiatae). Its structure [(12S)-6 alpha,19;15,16-diepoxy-6 beta-hydroxy-7 18)abeo-neo-cleroda- 4,13(16),14-trien-20,12-olide] was established by spectroscopic means, including an X-ray diffraction analysis. Teubetonin possesses a new 7 beta-homo-19(5-->18)abeo-neo-clerodane skeleton, the biogenesis of wh ich is briefly discussed.
