We have demonstrated that different enantioenriched 2-arylpropylsufonylbenzene derivatives are very useful building blocks for the synthesis of aromatic bisabolane sesquiterpenes. Their preparation and the exploitation of their chemical reactivity have been comprehensively investigated. Accordingly, the naturally occurring bisabolane sesquiterpenes (-)-curcuphenol, (-)-xanthorrhizol, (+)-glandulone A, (+)-curcudiol, (+)-turmerone and (+)-curcudiol-10-one were synthesized in high enantiomeric purity. It is worth noting that the compounds (+)-curcudiol-10-one and (+)-glandulone A were prepared in enantioenriched form for the first time. Through the proposed synthetic approaches, we were able to confirm both chemical structures and the absolute configurations previously assigned to the two aforementioned sesquiterpenes.

The enantioselective total synthesis of heliannuols D and A, which exhibits allelopathic activity, was discussed. The enantioselective total synthesis included base-mediated intramolecular cyclisation of phenolic epoxide. The analysis showed the preparation of configurationally defined enantiopure epoxide whose intramolecular aryl ether-forming reaction provided heliannuol D and/or heliannuol A.
