Sclareol is oxidised with ozone, followed by treatment with alkaline hydrogen peroxide to give sclareol oxide. The sclareol oxide is then oxidised with an organic hydroperoxide, preferably tert-butyl hydroperoxide, to give 12-acetyl-norlabdane oxide. The 12-acetyl-norlabdane oxide is converted to 12-acetoxy-norlabdane oxide by oxidation with an organic peracid, preferably peracetic acid. The 12-acetoxy-norlabdane oxide is then reduced to norlabdane oxide with sodium borohydride in the presence of a transition metal salt. The reaction scheme of EP 0882191A may be represented as follows:
