oleanane triterpenoids isolatedfrom Fatsia polycarpa Hayata were synthesized through chemical transformations. Acetylation was effected by reaction with aceticanhydride in pyridine to afford compounds 1-5, while compound 6 was obtained using 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (EDC·HCl) in CH2Cl2. The others derivatives 7-9 were obtained in reactions of the corresponding triterpenoids
