説明

Treatment of abietic acid with a catalytic amount of iodine at higher temperatures produced several novel resin acids and unsaponifiable matters along with dihydroabietic acid and dehydroabietic acid which were reported previously. These products were separated and the structures were determined on their spectral data. When abietic acid was treated with 0.5 mol% iodine at 250°C for 30 min, the products were secodehydroabietic acid (24%), podocarpatrienoic acid (6%), demethyldehydroabietic acid (10%), octahydroretene (6%), hexahydroretene (1%), and tetrahydroretene (1%). Possible reaction mechanisms were suggested on the basis of results under various reaction conditions.
