Studies aimed at a comparison of chemical, biomimetic (Gif system GoAggIII)and enzymatic (CHMO) transformations of natural ( )-10β,14-dihydroxy-allo-aromadendrane have led to preparation of an eight-member sesquiterpene lactone.

sesquiterpenes and total syntheses of (+)-dysodensiol F, (+)-10β,14-dihydroxy-allo-aromadendrane, and (−)-dendroside C aglycon starting from a versatile hydroazulene intermediate were accomplished. The key features of these synthesesinvolve late-stage carbene-mediated diastereoselective cyclopropanation, construction of an unusual cis-fused-hydroazulene skeleton via intramolecular Dieckmann condensation

sesquiterpenoids of the skeletal types caryophyllane, cadinane, oplopane, eudesmane, allo-aromadendrane and 4-epi-guaiane, were isolated from Pulicaria paludosa. Their structures were established mainly by NMR techniques and chemical transformations. Four of them are new natural products. Three flavonoids and some simple phenolic derivatives were also isolated.
