Abstract
2,3-Seco-2,3-diacids of the 28-hydroxy-20(29)-lupene and 28-hydroxylup ane series (VIIa and VIIb, respectively) and their derivatives VIII - XIV were prepared from 28-acetoxy-20(29)-lupen-3-one (IIIa) and 28-ace toxy-3-lupanone (IIIb), respectively, by oxidation to diosphenols Va a nd Vb and subsequent oxidative cleavage of the C(2)-C(3) bond.
