Abstract
(-)-Xanthorrhizol (1) isolated from the rhizomes of Curcuma xanthorrhiza has been transformed to several bisabolane-type sesquiterpenoids, in a stereoselective manner. 10R- and 10S-10,11-dihydro-10,11-dihydroxyxanthorrhizols (2, 3), (-)-curcuquinone (4), (-)-curcuhydroquinone (5), helibisabonol A (7) and allylic alcohol 8 have been prepared from xanthorrhizol in optically active forms. All the routes involved a Sharpless AD to introduce the stereogenic centre at C-10
