Formal synthesis of (+)-grandisol from levoglucosenone

(+)-Grandisol, which is a component of the male-produced pheromone of the boll weevil, Anthonomus grandis, was synthesized from levoglucosenone. The key steps in the synthesis are the intramolecular diastereoselective four-membered ring construction and t
