Abstract

A selective route for the degradation of the unsaturated side chain of ent-labdanes has been devised, giving two useful synthons: 2β-acetoxy-14,15,17-trinor-ent-labdane-8,13- dione (5) and 2β-acetoxy-14,15-dinor-ent-labd-8(17)-en-13-one (7), the use of which for the preparation of terpenylquinone derivatives shall be reported elsewhere.
Keywords: Ent-labdanes; selective degradations; unsaturated side chain Ent-labdanes; selective degradations; unsaturated side chain
