Substituted and dehydro derivatives of 4-piperidinone are intermediates in alkaloid syntheses. [1] The N-protonated derivative is typically isolated as the hydrate (HO) 2 C(CH 2) 4 NH + 2. [2] It is a List I chemical in the United States as it is a precursor to fentanyl. Fentanyl synthesis using the Gupta method starting from 4-piperidone
1-Boc-4-AP (tert-butyl 4-(phenylamino)piperidine-1-carboxylate) is a compound used as an intermediate in the manufacture of fentanyl, as well as various related derivatives such as butyrylfentanyl, furanylfentanyl, benzylfentanyl and homofentanyl, among others.
The same is true for certain derivatives: N-formylpiperidine is a polar aprotic solvent with better hydrocarbon solubility than other amide solvents, and 2,2,6,6-tetramethylpiperidine is a highly sterically hindered base, useful because of its low nucleophilicity and high solubility in organic solvents.
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 .
The synthesis of 6-acetyl-1,2,3,4-tetrahydropyridine, an important bread aroma compound, starting from 2-piperidone was accomplished using t-boc anhydride. [14] See Maillard reaction ). The first step in this reaction sequence is the formation of the carbamate from the reaction of the amide nitrogen with boc anhydride in acetonitrile using DMAP ...
CAS Number. 108-96-3 ... 4-Pyridone is an organic compound with the formula C 5 H 4 NH(O). It is a colorless solid. ... 4-Piperidone; Dehydroacetic acid; References
The tert-butyloxycarbonyl protecting group or tert-butoxycarbonyl protecting group [1] (BOC group) is an acid-labile protecting group used in organic synthesis. The BOC group can be added to amines under aqueous conditions using di- tert -butyl dicarbonate in the presence of a base such as sodium hydroxide :
