Hazard Information	Back Directory
[Description] 4-Piperidinone is a derivative of piperidine with the molecular formula C5H9NO. 4-Piperidone is used as an intermediate in the manufacture of chemicals and pharmaceutical drugs. 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. This multicomponent reaction is related to the Hantzsch pyridine synthesis.
[Uses] 4-Piperidone monohydrate hydrochloride was used in the generation of compound libraries based on sub-reactions of an Ugi multicomponent reaction (MCR).
[Synthesis] A method for synthesizing an intermediate 4-piperidone, comprising the following steps: (1) adding β-alanine methyl ester to ethanol, placing it in a reaction kettle, adding ethylene, mixing it well, lowering the temperature to 0°C, adding PS-AlC
