Investigation of the products of the ozonolysis of neoabienols

The ozonolysis of a mixture of 13Z- and 13E-neoabienols (I and III) leads, depending on the conditions, either to 8-hydroxy-14,15-bis-norlabd-11-en-13-one (IV) or to 8-hydroxdriman-11-oic acid (VI) or to driman-8,11-diol (VII). Compound (IV) undergoes hydrogenation smoothly with the formation of a mixture of 8-hydroxy-14,15-bisnorlabdan-13-one (X) and sclareol oxide (XI).Institute of Chemistry, Academy of Sciences of the Moldavian SSR, Kishenev.
