化学的特性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.
