Abstract
The structure and stereochemistry of abiesonic acid — a new triterpenoid with a modified 3,4-secolanostane carbon skeleton isolated in the form of the dimethyl ester from the oleoresin of the Siberian fir — has been established with the aid of x-ray structural analysis. On irradiation with UV light, this ester is converted reversibly into its 24Z- isomer.
