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.
将8,11,13-松香三烯-18-油酸酯(1b)和7-氧代8,11,13-松香三烯10和15转化为15-氢过氧-7-氧代-8,11,13-松香三烯13和16,通过催化的需氧氧化ñ -hydroxyphthalimide(NHPI)联合2,2'-偶氮二(4-甲氧基-2,4-二甲基戊腈)(V-70)在室温下,和几个松香烷和萜podocarpane从合成13和16。
