Unveiling the secret of vetiver's scent

Fragrance Chemistry
You may not have heard of vetiver oil, but your nose is almost certainly familiar with the characteristic woody fragrance that it lends to thousands of perfumes and colognes. Given the widespread use of this natural extract, it is surprising that the specific molecular component most responsible for the odor has remained ambiguous. List et al. report a total synthesis of the tricyclic vetiver constituent (+)-2- epi -ziza-6(13)en-3-one, which olfactometry supports as the most potent source of the woody-amber scent. An enantioselective Mukaiyama-Michael addition was key to setting the stereochemistry.
