4-Piperidone is an organic compound with the molecular formula OC(CH 2) 4 NH. It can be viewed as a derivative of piperidine. 4-Piperidone is used as an intermediate in the manufacture of chemicals and pharmaceutical drugs. Substituted and dehydro derivatives of 4-piperidinone are intermediates in alkaloid syntheses. [1]
N-Methyl-3-piperidyl benzilate (JB-336, BZ) Piperidine is also commonly used in chemical degradation reactions, such as the sequencing of DNA in the cleavage of particular modified nucleotides . Piperidine is also commonly used as a base for the deprotection of Fmoc - amino acids used in solid-phase peptide synthesis .
Hydrazone formation of 1-methyl-4-piperidone (1) with benzohydrazide (2) gives (3). Catalytic hydrogenation using Adams' catalyst gives the substituted hydrazine (6) after acid-catalyzed hydrolysis to remove the benzoyl group and neutralization.

N-Phenethyl-4-piperidinone (NPP) is a derivative of 4-piperidinone with the molecular formula C 13 H 17 NO. It is used as an intermediate in the manufacture of chemicals and pharmaceutical drugs such as fentanyl .
4-Hydroxy-1-methyl-4-(4-methylphenyl)-3-piperidyl 4-methylphenyl ketone is a dopamine transporter reuptake inhibitor used as a lead compound to find a DRI transporter site antagonist (i.e. a compound that fills the ligand binding site without inhibiting the flow of neurotransmitters to the degree that another ligand at its site would).
4-Pyridone exists a keto-enol tautomerism with its enol tautomer 4-hydroxypyridine. In solution, the keto tautomer is favoured, [4] and the enol tautomer only becomes important in very dilute solutions or solutions of non-polar solvents.
Piperidinones or piperidones are a class of chemical compounds sharing the piperidone skeleton. A classic named reaction for the synthesis of piperidones is the Petrenko-Kritschenko piperidone synthesis which involves combining an alkyl-1,3-acetonedicarboxylate with benzaldehyde and an amine. [1]
