[Synthesis of new olean-18(19)-ene derivatives from allobetulin].
Effective synthesis of new olean-18(19)-ene triterpenoids based on interaction of allobetulin or its acetate with phosphorous oxychloride in pyridine under reflux is described. The structures of the synthesized 17-chloromethyl-oleane-18(19)-enes have been established with the help of NMR-spectroscopy and X-Ray analysis.
