Abstract
Methyl 3-O-acetylbetulinate (1) on refluxing with m-chloroperbenzoic a cid in a molar proportion in chloroform affords methyl 3 eta-acetoxy-3 0-hydroxylup-20(29)-en-28-carboxylate (3) and lupenyl acetate (2) furn ishes 3 beta-acetoxy-3O-hydroxy-lup-20(29)-ene (4). The structures of the compounds have been established on the basis of elemental analysis and spectral data.
