Heliangolides, Trachylobane, and Villanovane Derivatives from Viguiera SpeciesFrom the aerial parts of Viguiera cordata in addition to budlein A (3) and isoatripliciolide (5) two further heliangolides (6 and 7) were isolated. The aerial parts of V. pazensis afforded in addition to known compounds three trachylobane derivatives (17-19) as well as a further villanovane derivative (22). The structures were elucidated by spectroscopic methods and some chemical transformations.
Notes:
Aus den oberirdischen Teilen von Viguiera cordata werden neben Budlein A (3) und Isoatripliciolid (5) zwei weitere Heliangolide (6 und 7) isoliert. Die oberirdischen Teile von V. pazensis liefern neben bekannten Verbindungen drei Trachyloban-Derivate (17-19) sowie ein weiteres Villanovan-Derivat (22). Die Strukturen werden durch spektroskopische Methoden und einige chemische Umwandlungen geklärt.
