2-N-PENTYLCYCLOPENTANONE is a colorless liquid with
a complex floral, aromatic, fruity odor and a lactonic undertone.
2-Pentylcyclopentanone and its higher homolog 2-heptylcyclopentanone are prepared by aldol condensation of cyclopentanone with the
corresponding aliphatic aldehydes to give 2-alkylidenecyclopentanone and subsequent
hydrogenation of the double bond. The aldol reaction can be performed
efficiently by using N-containing bases such as proline and piperidine, in the
presence of acid. The (R)-enantiomers of 2-alkylcyclopentanones
can be prepared in high optical purity from 2-alkylcyclopentenol esters or
2-alkylidene cyclopentanones by using enzymatic methods.
2-Pentylcyclopentanone is used in jasmine, herbal, and lavender compositions. | [Flammability and Explosibility]
