Add to ORKGp. 261-266,May/June.Relative stereochemistry determination of pimaradienes through oxidative products. 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
