Abstract
New processes have been developed which allow the stereoselective synt heses of the ambergris ketals 8 alpha,13;13,17-diepoxi-14,15-dinorlabd ane 1 and 8 beta,13;13,17-diepoxi-14,15-dinorlabdane 2, through select ion of the appropriate catalyst for the delta,epsilon-epoxycarbonyl re arrangement of the key intermediate 3, which is, in turn, obtained by controlled oxidation of anticopalic acid 6.
