Synthesis of wiendendiol-A and wiedendiol-B from Labdane diterpenes

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 85.95- driman-11-al (26), by two alternative routes starting from 7 and (+)-cis- abienol (8) is also described. 21 prepared from protocatchhualdehyde (17) was used as somatic synthon for preparing 1 and 2.
