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.
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 ).
Piperidine is widely used to convert ketones to enamines. [23] Enamines derived from piperidine are substrates in the Stork enamine alkylation reaction. [24] Upon treatment with calcium hypochlorite, piperidine converts to N-chloropiperidine, a chloramine with the formula C 5 H 10 NCl.
It is advised to check the references for photos of reaction results. [1] Reagent testers might show the colour of the desired substance while not showing a different colour for a more dangerous additive. [2] For this reason it is essential to use multiple different tests to show all adulterants.
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 ...
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]
[1] It consists of a piperidine ring with a carboxylic acid moiety in the iso position (and as such is also known as "4-piperidinecarboxylic acid"). References
4-Amino-2,2,6,6-tetramethyl-4-piperidine is an organic compound with the formula H 2 NCH(CH 2 CMe 2) 2 NH (where Me = CH 3). Classified as a diamine, it is a colorless oily liquid. The compound is an intermediate in the preparation of Bobbitt's salt, an oxidant used in organic synthesis. It is prepared by the reductive amination of the ...
