Cyclopentene is a chemical compound with the formula C₅H₈.^[1] It is a colorless liquid with a petrol-like odor. It is one of the cycloalkenes.

Cyclopentene is produced industrially in large amounts. It is used as a monomer for synthesis of plastics, and in a number of chemical syntheses.

It can be obtained from vinylcyclopropane in the vinylcyclopropane-cyclopentene rearrangement.

A highly stereoselective catalytic alkylation sequence for the synthesis of highly functionalized and versatile five-membered-ring compounds bearing all-carbon quaternary stereocenters was developed. Enantioselective desymmetrization of achiral cyclopentene-1,3-diones was thus executed by chiral Cu-
