3-Methyl-2-pentylcyclopent-2-enon Chemische Eigenschaften,Einsatz,Produktion Methoden

Chemische Eigenschaften

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.

synthetische

Hexyl bromide plus levulinic ester yields a lactone, which is reacted with polyphosphoric acid or phosphorus pentoxide to produce hydrojasmone.
