Description and Uses
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].
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.
