Methyl 8, 11, 13-abietatriene-18-oate (1b) and 7-oxo-8, 11, 13-abietatrienes 10 and 15 were converted into 15-hydroperoxy-7-oxo-8, 11, 13-abietatrienes 13 and 16 by aerobic oxidation catalyzed by N-hydroxyphthalimide (NHPI) combined with 2, 2′-azobis (4-methoxy-2, 4- dimethylvaleronitrile)(V-70) at room temperature, and several abietane and podocarpane terpenes were synthesized from 13 and 16.
