Abstract
A novel one-step stereospecific synthesis of C-2-nor-1 beta-hydroxy-2- oxa-lupenone 3 is described through potassium hydroxide (KOH)-dimethyl sulphoxide (DMSO) mediated oxidation of lupenone 2. Formation of 3 is associated with an unusual oxidative skeletal rearrangement of ring-A in lupenone under the condition of oxidation.
