clear colorless to pale yellow liquid | [Uses]
L-Menthone is used in perfumery and cosmetics for its characteristic aromatic and minty odor. And it is also used in synthesis of agrochemicals, and dyestuff. | [Definition]
ChEBI: (-)-menthone is a menthone that is cyclohexanone substituted by a methyl and an isopropyl group at positions 5 and 2 respectively (the 2S,5R-stereoisomer). It is an enantiomer of a (+)-menthone. | [General Description]
(-)-Menthone is a monoterpenoid compound found in the essential oil extracted from the maturing peppermint (Mentha piperita L.) leaves. | [Biochem/physiol Actions]
Taste at 50 ppm | [Synthesis]
1) Preparation of the chiral catalyst [RuCl₂(S)-XylBINAP(S)-DAIPEN].
2) Selective hydrogenation: D-Pulegone is hydrogenated at 70°C under 100 atm H₂ pressure for 23 h in the presence of the catalyst. After removing solvents, levomenthol is obtained by |
