The first enantiospecific synthesis of the cholesteryl ester transfer protein (CETP) inhibitor wiedendiol-B (1) is described. The drimanic synthon was prepared from (-)-sclareol (4) and (+)-cis-abienol (13) by two alternative routes. The key steps of the reaction sequences are the chemo- and diastereoselective hydrogenation of the C8-C9 double bond of enal 6 and the stereoselective cationic hydrogenation of the hydroxyl group of 13, respectively, and the selective reduction of benzyl groups of 15.
