2-Cyclopenten-1-one Chemical Properties,Uses,Production
Description
2-Cyclopentenone contains two functional groups, a ketone and an alkene. It is a colourless liquid. 2-cyclopenten-1-one selectively induces the expression of the 70-kDa HSP (HSP70) in human cells through cycloheximide-sensitive activation of heat shock transcription factor 1 (HSF1). It is a natural product found in Perilla frutescens[1].
Chemical Properties
clear yellow liquid
Uses
2-Cyclopenten-1-one is a versatile electrophile employed in various addition reactions including conjugate addition of organocopper nucleophiles, Michael reaction with silyl enol ethers and siloxanes. It is also used in Diels-Alder cycloadditions and phosphoniosilylations.
Preparation
2-Cyclopentenones can be synthesized in a number of ways. One of the routes involves elimination of α-bromo-cyclopentanone using lithium carbonate and Claisen condensation-decarboxylation-isomerization cascades of unsaturated diesters as shown below.
The acid-catalyzed dehydration of cyclopentanediols affords cyclopentenone.
As a functional group, the synthesis of 2-cyclopentenones is accomplished in a variety of other ways, including the Nazarov cyclization reaction from divinyl ketones, Saegusa–Ito oxidation from cyclopentanones, ring-closing metathesis from the corresponding dienes, oxidation of the corresponding cyclic allylic alcohols, and the Pauson–Khand reaction from alkenes, alkynes, and carbon monoxide.
