Synthesis of wiedendiol-A and wiedendiol-B from labdane diterpenes
AF Barrero, EJ Alvarez-Manzaneda, R Chahboun - Tetrahedron, 1998 - Elsevier
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.
