Description

2-Methylcyclopent-2-enone is a bench-stable, electron-deficient enone featuring a conjugated C=C–C=O system. This cyclic ketone integrates readily into Diels-Alder reactions and serves as a key building block in natural product synthesis. Its sterically accessible carbonyl and alkene moieties facilitate selective functionalization under mild conditions.
