2-Pentyl-3-methyl-2-cyclopenten-1-one Chemical Properties,Usage,Production

  • 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.
  • Chemical Properties 3-Methyl-2-(n-pentanyl)-2-cyclopenten-1-one has a fresh, fruity, jasmine odor with woody and herbal nuances.
  • 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.
  • Taste threshold values Taste characteristics at 10 ppm: sweet, floral, green, herbal with a citrus nuance.
