2-Piperidone Chemical Properties,Usage,Production

Chemical Properties

white to yellowish low melting crystalline mass

Uses

δ-Valerolactam is a useful synthetic intermediate. It is an intermediate used to synthesize Cenicriviroc (C256550), an experimental drug candidate for the treatment of HIV infection. It is also a starting material for a new route to hexahydrojulolidines, using intramolecular 1,4-cycloaddition.

Definition

ChEBI: 2-Piperidone is a delta-lactam that is piperidine which is substituted by an oxo group at position 2. It has a role as an EC 1.2.1.88 (L-glutamate gamma-semialdehyde dehydrogenase) inhibitor. It is a member of piperidones and a delta-lactam.

Preparation

2-Piperidone can be obtained from cyclopentanone as raw material by a two-step reaction.
