Oxidative Degradations of the Side Chain of Unsaturated Ent-labdanes. Part II
A route for the degradation of the side chain of ent-labdane derivatives has beendevised, giving the useful synthon 2β,12-dihydroxy-13,14,15,16,17-pentanor-ent-labdane-8-one (8). The use of this compound in the preparation of terpenylquinone derivatives shallbe reported elsewhere. In addition we...
