Abstract :
Two procedures to introduce an oxygenated function into the C-14 of abietane diterpenes with complete regioselectivity have been developed. Utilizing these, the synthesis of the antileishmanial quinone (−)-12-deoxyroyleanone (1) and a formal synthesis of antitumour and immunosuppressant (−)-triptonide (7) and (−)-triptolide (8) from (+)-abietic acid (13) have been carried out.
