TL;DR: In this article, Schistostephium species were used to identify 43 new compounds, including isocomene, bisabolene, eudesmane and nerolidol derivatives, and a prostaglandin-like acid.
TL;DR: In this paper, the arene-olefin meta-photocycloaddition is shown to provide the basis for an effective and general approach to polyquinane natural products as demonstrated by the synthesis of (±)-isocomene ( 5 ) in five steps based on Z-2bromo-2-butene and 2-bromotoluene.
TL;DR: In this paper, the authors investigated 11 South African Helichrysum species and established the structures of several phloroglucinol derivatives by synthesis, including nine diterpenes, a derivative of isocomene and an α-pyrone derivative.
