title: [A one-step approach to the synthesis of germanicane triterpenoids from allobetulin].
abstract: A new triterpenoid of the germanicane series 3S,19R-diacetoxy-17-iodomethylenoleanane has been synthesized by treating allobetulin with acetyl chloride and sodium iodide in acetonitrile. The structure of the compound obtained has been corroborated by X-ray analysis data.
