| Abstract: | A mixture of diastereomeric 3-acetoxy-(2,3),(19β,28)-diepoxyoleananes was prepared via reaction of 3-acetoxy-19β,28-epoxyolean-2-ene
with m-chloroperbenzoic acid. Directed rearrangement of these formed 2β-acetoxy-19β,28-epoxyolean-3-one whereas heating of
them in amines produced oleanane-type enamines.
