  Synthesis of wiedendiol-A and wiedendiol-B from labdane diterpenes

  摘要：

  Two efficient enantiospecific syntheses of wiedendiol-A (1) from (-)-sclareol (7), via 11-bromo-8-drimene (11) and 8-drimen-11-al (3), are reported. The first enantiospecific synthesis of wiedendiol-B (2), via 8S,9S-driman-11-al (26), by two alternative routes starting from 7 and (+)-cis-abienol (8) is also described. 21 prepared from protocatechualdehyde (17) was used as aromatic synthon for preparing 1 and 2.

  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 C-8-C-9 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.
