KAURANE SUCCINATES AND PRENYLATED AROMATICS FROM ODIXIA ANGUSTA AND OZOTHAMNUS OBCORDATUS

Article abstract of DOI:10.1016/0031-9422(91)85127-L

The aerial parts of Odixia angusta afforded five ent-kaurane succinates and a nor-derivative as well as diprenyl p-coumarate and a hemiacetal derived from the latter.Ozothamnus obcordatus gave five prenylated p-hydroxybenzoic acids probably formed by oxidative cleavage of the coumarates.The structures were elucidated by high field NMR techniques.Key Word Index - Odixia angusta; Ozothamnus obcordatus; Compositae; diterpene; kauranes; nor-kaurane; prenylated coumaric acids.
