The relative and absolute configurations of an oxygenated bisabolane natural product, isolated from Ligularia lankongensis, were determined by synthesis. All four possible stereoisomers and their tiglate analogues were synthesized from R-(-)-carvone, and their 1H and 13C NMR spectra were compared to establish the 6R,8S,10S configuration. The stereoselective synthesis of the natural product was also achieved, featuring Brown allylation, vanadium-catalyzed epoxidation, and the Mitsunobu reaction.

The absolute configuration of (+)-2,7(14),10-bisabolatrien-1-ol-4-one, a peculiar sesquiterpenol in the Japanese cedar, Cryptomeria japonica, was determined as (1S,6R)-2,7(14),10-bisabolatrien-1-ol-4-one by comparing the specific rotation values of crypto
