摘要：

The heartwood of the Fijian species Euphorbia fidjiana has yielded three new ent-pimaren-3-ones, a new ent-abietadienolide, as well as the known compounds jolkinolides A and E. The structures and relative stereochemistry of the ent-pimaren-3-ones have been determined from high field NMR studies. The structures of the γ-lactones were assigned on the basis of NMR data and an X-ray structure analysis. The structures of the previously reported pseudojolkinolides have been revised. © 1990.
