Oxidative degradations of the side chain of unsaturated ent-labdanes. Part I

Molecules. 2007 Mar 6;12(3):318-27. doi: 10.3390/12030318.

Abstract

A selective route for the degradation of the unsaturated side chain of ent-labdanes has been devised, giving two useful synthons: 2beta-acetoxy-14,15,17-trinor-ent-labdane-8,13- dione (5) and 2beta-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.
