- The organic compound primarily responsible for the characteristic odor of musk is muscone.
- Civetone is closely related to muscone, the principal odoriferous compound found in musk.
- The chemical structure of muscone was first elucidated by Lavoslav Ru ~ i ka.
- Isotopomers of muscone have been used in a study of the mechanism of olfaction.
- Muscone has been synthesized as the pure ( " )-enantiomer as well as the racemate.
- Since obtaining natural musk requires killing the endangered animal, nearly all muscone used in perfumery today is synthetic.
- (a ) Asymmetric addition of alkenylzinc to aldehyde in the total synthesis of muscone . ( b ) Detailed steps for the reaction.
- Natural muscone is obtained from musk, a glandular secretion of the musk deer, which has been used in perfumery and medicine for thousands of years.
- Although muscone, the primary macrocyclic compound of musk was long known, it was only in 1926 that Leopold Ruzicka was able to synthesize this compound in very small quantities.
- Several related derivatives are also important in the fragrance industry, especially those with alkene group in the backbone such as civetone, muscone, and velvione ( 5-cyclohexadecenone ).
- Here, with a group of his doctoral students, he proved the structure and existence of the compounds of muscone and civet, the scents derived from the musk deer and the civet cat.
- However this claim has been challenged by another report that the human musk-recognizing receptor, OR5AN1 that robustly responds to cyclopentadecanone and muscone, fails to distinguish isotopomers of these compounds in vitro.
- Specifically, Block et al . report that the human musk-recognizing receptor, OR5AN1, identified using a heterologous olfactory receptor expression system and robustly responding to cyclopentadecanone and muscone, fails to distinguish isotopomers of these compounds in vitro.
- Macrocyclic lactones ( cyclopentadecanolide, 15-pentadec-11 / 12-enolide ) have odors similar to macrocyclic ketones of animal origin ( muscone, civetone ), but they can be prepared more easily, for example, by depolymerization of the corresponding linear polyesters.
- In response to the 2013 paper on cyclopentadecanone, Block et al . report that the human musk-recognizing receptor, OR5AN1, identified using a heterologous olfactory receptor expression system and robustly responding to cyclopentadecanone and muscone ( which has 30 hydrogens ), fails to distinguish isotopomers of these compounds in vitro.
- For example, the key cyclization step in the total synthesis of ( R )-(-)-Muscone was an intramolecular asymmetric addition of a vinylzinc derivative to an aldehyde using a chiral amino-isoborneol ligand ( Figure " ( a ) Asymmetric addition of alkenylzinc to aldehyde in the total synthesis of muscone " ).

- In response to Turin's 2013 paper, involving deuterated and undeuterated isotopomers of the musk cyclopentadecanone, report that the human musk-recognizing receptor, OR5AN1, identified using a heterologous olfactory receptor expression system and robustly responding to cyclopentadecanone and muscone ( which has 30 hydrogens ), fails to distinguish isotopomers of these compounds in vitro.
- Global replacement of all hydrogens in muscone was achieved by heating muscone with Rh / C in D 2 O at 150 �C . It was found that the human musk-recognizing receptor, OR5AN1, identified using a heterologous olfactory receptor expression system and robustly responding to muscone, fails to distinguish the so-prepared isotopomers of muscone in vitro.
