摘要

Abstract New olean-18 (19)-ene triterpenoids were effectively synthesized by the interaction of allobetulin or its acetate with phosphorous oxychloride in refluxing pyridine. The structures of the synthesized 17-chloromethyloleane-18 (19)-enes were confirmed by NMR spectroscopy and X-ray analysis.
