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.
