Abstract
Khusimone (1). one of the main odor-donating compounds of vetiver oil, is subject of the following study on structure-odor relationship. The omittance of the methano bridge of the tricyclic khusimone should lea d to the bicyclic partial structure(-)-2. Unexpectedly, (-)-2 could no t be obtained since epimerization favored(-)-16. The stereochemical ke y step of the synthesis of the hydrazulene nucleus is based on a highl y diastereoselective conjugate addition to a chiral oxocyclopent-1-ene -1-carboxylate.
