Cyclopentanone is common precursor to fragrances, especially those related to jasmine and jasmone. Examples include 2-pentyl- and 2-heptylcyclopentanone. [4] It is a versatile synthetic intermediate, being a precursor to cyclopentobarbital. [5] Cyclopentobarbital, a drug made from cyclopentanone
Cyclopentanone: Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). ...
2-Cyclopentenones can be synthesized in a number of ways. One of the routes involves elimination of α-bromo-cyclopentanone using lithium carbonate [2] and Claisen condensation-decarboxylation-isomerization cascades of unsaturated diesters as shown below. [3] Industrial synthesis of cyclopentenone
Sigma Advanced Genetic Engineering (SAGE) Labs is a division within Sigma-Aldrich that specializes in genetic manipulation of in vivo systems for special research and development applications. It was formed in 2008 to investigate zinc finger nuclease technology and its application for disease research models.
The compound is prepared by base-catalyzed condensation of 1-hydroxyhexane-2,5-dione, a derivative of hydroxymethylfurfural. [2]The structure has been confirmed by X-ray crystallography. [2]
Cyclopentenone prostaglandins are a subset of prostaglandins (PGs) or prostanoids (see Eicosanoid §§ Classic eicosanoids and Nonclassic eicosanoids) that has 15-deoxy-Δ12,14-prostaglandin J2 (15-d-Δ12,14-PGJ2), Δ12-PGJ2, and PGJ2 as its most prominent members but also including PGA2, PGA1, and, while not classified as such, other PGs. 15-d-Δ12,14-PGJ2, Δ12-PGJ2, and PGJ2 share a common ...

For instance, the reaction of cyclopentanone with diazomethane forms cyclohexanone (shown below). The Büchner ring expansion reactions utilizing diazoalkanes have proven to be synthetically useful as they can not only be used to form 5- and 6-membered rings, but also more unstable 7- and 8-membered rings.
