| 2-Pentyl-3-methyl-2-cyclopenten-1-one Usage And Synthesis |
Chemical Properties | 3-Methyl-2-(n-pentanyl)-2-cyclopenten-1-one has a fresh, fruity, jasmine odor with woody and herbal nuances. | Chemical Properties | 2-Pentyl-3-methyl-2-cyclopenten-1-one is a colorless,
slightly viscous liquid with a typical jasmine odor, resembling that of the naturally
occurring (Z)-jasmone. Dihydrojasmone is produced by an acid-catalyzed
rearrangement of 4-methyl-??-decalactone, which is readily obtained by
radical addition of 2-octanol to acrylic acid.
Dihydrojasmone is used in perfumery in jasmine bases and, more generally, in
floral and fruity fragrances. | Occurrence | Has apparently not been reported to occur in nature. | Preparation | Hexyl bromide plus levulinic ester yields a lactone, which is reacted with polyphosphoric acid or phosphorus pentoxide
to produce hydrojasmone. | Definition | ChEBI: 3-methyl-2-pentylcyclopent-2-en-1-one is a cyclic ketone. | Taste threshold values | Taste characteristics at 10 ppm: sweet, floral, green, herbal with a citrus nuance. | Synthesis Reference(s) | Canadian Journal of Chemistry, 56, p. 2301, 1978 DOI: Journal of the American Chemical Society, 92, p. 7428, 1970 DOI: |
