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.
[9] [10] [11] Both of them obtained piperidine by reacting piperine with nitric acid. Industrially, piperidine is produced by the hydrogenation of pyridine, usually over a molybdenum disulfide catalyst: [12] C 5 H 5 N + 3 H 2 → C 5 H 10 NH. Pyridine can also be reduced to piperidine via a modified Birch reduction using sodium in ethanol. [13]
20% piperidine in DMF (Fmoc group has an approximate half life of 6 seconds in this solution) [8] 5% piperazine, 1% DBU and 1% formic acid in DMF. This method avoids the use of strictly controlled piperidine. [9] No side product was observed for a peptide with 9 residues synthesized with this method. [10]
It is most efficacious as a releaser of norepinephrine, with an EC 50 of 109 nM (DA), 41.4 nM (NE), and 5,246 nM . [ 2 ] It also functions as a weak monoamine oxidase inhibitor (MAOI) ( IC 50 Tooltip half-maximal inhibitory concentration = 130 μM for MAO-A Tooltip monoamine oxidase A and 750 μM for MAO-B Tooltip monoamine oxidase B ).
4-Aminopyridine is also used under the trade name Avitrol as 0.5% or 1% in bird control bait. It causes convulsions and, infrequently, death, depending on dosage. [18] The manufacturer says the proper dose should cause epileptic-like convulsions which cause the poisoned birds to emit distress calls resulting in the flock leaving the site; if the dose was sub-lethal, the birds will recover ...
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 :
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 .
