Kaurane succinates and prenylated aromatics from Odixia angusta and Ozothamnus obcordatus
摘要:
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.
