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-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 .

Piperidine is an organic compound with the molecular formula (CH 2) 5 NH. This heterocyclic amine consists of a six-membered ring containing five methylene bridges (–CH 2 –) and one amine bridge (–NH–).
4-Benzylpiperidine is a drug and research chemical used in scientific studies. It has been encountered as a designer drug. [1] Pharmacology
Two early syntheses of this compound are those of Leonard and Hauck, [5] and Hall. [4] These are very similar in principle: Leonard and Hauck reacted phorone with ammonia, to produce 2,2,6,6-tetramethyl-4-piperidone, which was then reduced by means of the Wolff–Kishner reduction to 2,2,6,6-tetramethylpiperidine.
Piperidione (trade name Sedulon) is a sedative drug, structurally related to methyprylon and pyrithyldione.It used to be marketed by Roche as a cough medicine available in liquid form.
Therefore, the product of the reaction is not a bicyclic structure (see tropinone and pseudopelletierine) but a 4-piperidone. The synthesis of tropinone can be seen as a variation of the Petrenko-Kritschenko reaction in which the two aldehyde functions are covalently linked in a single molecule.
