Summary: | <abstract language="eng">Pimaradienes, including isopimaradienes, with an endocyclic double bond between C-9 and C-11 are uncommon compounds in nature. The diterpenoid pimar-9(11),15-dien-19-oic acid (1) was isolated from Mikania triangularis (Asteraceae) and the correct stereochemistry of 1was established by ¹H and 13C NMR studies of several oxidative products, mainly epoxides, of this compound and its double bond isomers. |
