General description

(-)-Menthone is a monoterpenoid compound found in the essential oil extracted from the maturing peppermint (Mentha piperita L.) leaves.

(-)-Menthone can undergo hydrogenation to yield a mixture of (-)-menthol and (+)-neomenthol.

Application

(-)-Menthone may be used to synthesize chiral neomenthyl derivatives, optically pure α-ferrocenylalkylamines and optically active polyalkylcyclohexanones.
