The system I2/dimethyl sulfoxide mediates the one-step transformation of α-isopropylidene ketones into furan rings following a biomimetic approach. This methodology has been used for the synthesis of terpene furans such as mintfurane, curzerene, atractylon, and isoatractylon, all of them possessing interesting biological activities. The synthesis of linderazulene directly from 4,5-epoxygermacrone via a cascade reaction shows the potential of this protocol. Additionally, this compound proved to show significant ixodicidal activity.

The ethereal extract of the Antarctic gorgonian Dasystenella acanthina was found to contain three main nonpolar and relatively transient sesquiterpene metabolites (1-3), which were isolated and submitted to spectral analysis. Two of them were identified as the previously reported compounds trans-β-farnesene (1) and isofuranodiene (3), whereas the third metabolite, the furanoeudesmane 2, was unknown. The structure elucidation of this new sesquiterpene was solved mainly on the basis of its spectral properties and correlation with known compounds.

Tree novel sesquiterpene alcohols, shizuka-acoradienol (2), shizukafuranol (3) and shizukolidol (4), were isolated from Chloranthus japonicus Sieb. (Japanese name: Hitori-shizuka, Chloranthaceae).Their structures were elucidated on the basis of their physicochemical properties and some chemical reactions.Furanodienone (5), scopoletin (6a) and isoscopoletin (6b) were also isolated from this plant.
